Bourbon Ají Coffee Explained: The Rare Colombian Variety That Tastes Nothing Like Chili

 Has anyone else noticed that we haven’t heard much about “Bourbon Ají” lately? In fact, I’m sure plenty of coffee drinkers still have no idea what it is. Looking back at my previous posts, I usually only mentioned Bourbon Ají in café visits or in a dedicated flavor review, but I never really wrote about its background in detail. Recently, though, I found myself thinking about it again, so I figured it was finally time to dedicate an entire article to this “coffee aristocrat” whose name has seriously held it back.

Bourbon Ají had a brief moment in the spotlight a few years ago, largely thanks to its impressive performance in the 2021 COE (Cup of Excellence), where it placed sixth. I still remember having the chance to taste some of the competition samples before the event itself. During a blind cupping session, Bourbon Ají immediately stood out to me and left a lasting impression.

So where exactly does this strange name come from? And does it actually have anything to do with chili peppers?

Well, not really. The coffee isn’t “spicy” at all. It’s simply a coffee variety that resembles chili peppers. In Colombia, growers noticed that the cherries were long and pointed, much like ají peppers, and even the green beans carried a faint spicy-herbal aroma. That’s how it earned the name “Bourbon Ají.”

What makes it even more interesting is that despite the word “Bourbon” in its name, recent genetic testing has confirmed that Bourbon Ají is not actually part of the Bourbon family. Instead, it’s an ancient Ethiopian landrace variety, genetically much closer to the legendary Geisha.

Honestly, when I first evaluated Bourbon Ají myself, the dry fragrance immediately revealed a noticeable spice character — something reminiscent of lightly charred peppers. But once brewed, the cup settles back into a much more familiar and elegant coffee profile. I often find juicy notes of apricot and peach layered together with bright, refreshing acidity that makes your mouth water. Some Bourbon Ají lots also carry delicate hints of ginger, lemongrass, or Earl Grey tea-like spice. Overall, it’s best known for its refined florals and remarkable complexity.

That said, have you noticed how little people talk about Bourbon Ají these days?

It reminds me of varieties like Sidra or Pink Bourbon, which were once considered trendy and exotic but have gradually become more common everyday specialty coffees. Coffee varieties, in many ways, follow trends just like fashion. Different years bring different obsessions.

A couple of years ago, Bourbon Ají exploded on social media and within the specialty coffee scene thanks to its unusual name and fascinating backstory. It quickly became a highly sought-after “internet-famous” bean. But once the excitement of novelty faded, it naturally returned to a smaller niche audience of dedicated specialty coffee enthusiasts, and demand dropped accordingly.

There’s also a more practical reason behind its disappearance from the spotlight: Bourbon Ají is still an extremely rare variety. Although ancient in origin, it was only relatively recently rediscovered and is currently grown in limited quantities within specific micro-regions of Colombia. Production volumes are incredibly small. For most roasters, it’s more of an occasional limited-release gem rather than a consistently available staple coffee.

From a farmer’s perspective, planting high-yield, disease-resistant varieties simply makes more economic sense. Bourbon Ají produces lower yields and is more difficult to cultivate. Without strong enough market prices, there’s very little incentive for farmers to switch over to large-scale production.

And then there’s the name itself — both its greatest advantage and its biggest weakness.

The word “ají” helped the coffee go viral in the beginning, but it also created confusion among consumers. Many people naturally wondered, “Wait… is this coffee actually spicy?” Once the novelty wore off, the unusual name may have even become a barrier preventing repeat purchases.

So to clarify once again: the “spice” in Bourbon Ají does not refer to the burning heat of capsaicin. That’s exactly why I always emphasize that it isn’t actually spicy. Instead, it carries a gentle herbal sweetness and aromatic spice character somewhat reminiscent of green peppers, bell peppers, and fresh herbs.

If you’re interested in exploring rare coffee varieties with unique flavor profiles like this, keep an eye on limited releases from specialty coffee roasters. Finding a great Bourbon Ají often requires a little luck — but when you do, it’s absolutely worth the experience.

Why Highly Sensitive People Make Exceptional Coffee Tasters | The Hidden Gift of HSPs

 Today, I want to share something a little more niche and deeply personal. It touches on certain traits that define who I am, and in many ways, this piece is about connecting psychology with sensory experience. Before I begin, I need to talk about a group known as Highly Sensitive People (HSPs). I myself am a very typical HSP.

People like us often grow up hearing things like, “You’re too sensitive,” or “You think too much.” Over time, this can create a lingering feeling of being fundamentally different from everyone else. But what many fail to realize is that this trait is actually an incredibly refined gift system. And in the world of coffee tasting, it almost feels like a playground specifically designed for HSPs.

I wanted to write this piece for those of you who are both highly sensitive and passionate about coffee. Through this screen, I hope to offer a sense of resonance, understanding, and recognition. I truly believe that highly sensitive people are misunderstood talents within the coffee world. Our nervous systems were never meant simply to endure the chaos of the world — they were also built to detect the most delicate shifts in flavor.

A sensitive palate is not a weakness. In a single cup of coffee, it can feel as though seven hundred different emotions are living inside me. When coffee meets sensitivity, it isn’t pickiness — it’s precision. In fact, I’d even say that for highly sensitive people, your sensitivity is the best cupping tool you could ever have. The transformation from “someone easily overstimulated” into a “hunter of flavor nuances” can be profoundly healing.

Highly sensitive people tend to process stimulation — including taste, aroma, and even caffeine’s physical effects — much more deeply than others. We also become overloaded more easily. Yet the very traits that exhaust you in daily life can become superpowers when it comes to coffee tasting. That’s one of the biggest reasons why I love coffee so much. In this world, my natural sensitivities feel amplified in the best possible way, turning something that once drained me into something that feels deeply empowering.

The mind of an HSP naturally connects every experience to layers of background, memory, detail, and meaning. We process information with unusual depth, which often shows up as slow decision-making and chronic overthinking. At the same time, this also explains why many highly sensitive people struggle with superficial socializing or large gatherings. Most of us prefer solitude, quiet reflection, or conversations with lifelong friends. A rich inner world matters far more to us than social performance.

Our thinking tends to be expansive and multi-threaded rather than strictly linear. Perhaps that’s why highly sensitive people are often perceived as intelligent. And this same mental wiring allows us to process coffee on multiple levels at once: flavor complexity, texture, temperature, aftertaste, and memory associations all simultaneously. Even without formal sensory training, many HSPs instinctively capture and remember flavors they’ve experienced. In everyday life, we unconsciously build an enormous internal archive of sensory references that sharpens our perception over time.

When highly sensitive people receive more stimulation than they can process, exhaustion or emotional overwhelm can follow. Emotional responses tend to run deep — both joy and discomfort are felt intensely. But the upside is extraordinary empathy. For many friends, HSPs feel almost like a source of light. Of course, that same empathy can also make us vulnerable to absorbing the emotions of others. Loud environments, bright lights, and multitasking can quickly become emotionally draining.

Yet this sensitivity also gives us an extraordinary awareness of the emotional texture of flavor. We can sense whether a coffee feels “bright and joyful” or “muted and heavy.” We notice tiny details others overlook: subtle sounds, faint aromas, slight temperature shifts, and delicate textural differences. We can even distinguish subcategories within a single flavor note — separating raspberry from blueberry, or blackcurrant from generic “berry.”

Whenever I visit a café, I always record my immediate flavor impressions and emotional reactions in my private social feed. I call these entries my “café journals” and “flavor notes.” Capturing those fleeting moments helps me preserve the emotional truth of the experience so I can later express it clearly in a calmer state of mind.

Sometimes friends leave comments like, “Your palate is unbelievable.” But honestly, I’ve never gone through systematic sensory training, nor have I ever been particularly interested in certifications like Q Grader. I believe that simply drinking widely, paying attention, and consistently documenting flavors naturally leads to dramatic sensory growth. Though I’ll admit — perhaps there really is a bit of talent involved.

When most people taste a coffee, they might simply think: “acidic.” But for a highly sensitive person, the brain instinctively breaks that sensation down into dimensions. What kind of acidity is it? Is it bright and sparkling, or soft and rounded with sweetness underneath? What accompanies the acidity? Is there sweetness balancing it, or bitterness supporting it? How does the acidity evolve over time — in the first second, the middle palate, and the lingering finish?

This isn’t a learned technique. It’s simply the brain’s default operating system. Our neural pathways automatically expand a single sensation into a multidimensional map.

What’s even more fascinating is that many of the most beautiful flavors in specialty coffee are fragile, fleeting, and easily overshadowed. Because highly sensitive people have lower sensory thresholds, we don’t need intense stimulation to perceive these nuances. That makes this trait incredibly valuable in coffee tasting. While others may need deliberate training and intense focus to occasionally detect such details, HSPs often receive them effortlessly and automatically. That’s also why highly sensitive tasters tend to describe flavor with extraordinary precision and structural detail.

Many HSPs also naturally experience cross-sensory associations while tasting coffee. This isn’t poetic exaggeration — it’s a genuine form of sensory blending. For example, whenever I drink Yemeni coffee, it feels wild, untamed, and strangely seductive. Coffees brewed through flannel filters or extreme extraction methods often feel incredibly velvety, as though the liquid glides softly across the tongue and slips effortlessly into the mouth.

Because of this, my tasting notes never feel like dry lists of flavor descriptors. They become miniature narratives filled with warmth, imagery, and emotion. And I think that’s why many people who read my reviews say they feel as if they’ve personally tasted the coffee themselves. In the world of specialty coffee, this kind of emotional tasting language is actually one of the highest forms of communication.

Highly sensitive people also tend to compare and archive every new sensory experience against a vast database of past memories. Taste a “berry note,” and the brain instantly retrieves every berry you’ve ever eaten. Taste sweetness, and the mind doesn’t stop at the word “sweet.” Instead, it differentiates: the transparent sweetness of sugarcane juice, the floral sweetness of honey, the bittersweet depth of caramel, or the juicy sweetness of ripe fruit balanced by acidity.

To be honest, I’ve never intentionally memorized a flavor wheel. Sometimes I feel like my brain itself is already a highly sophisticated sensory dictionary.

It may sound a little mystical, but within the language of specialty coffee, coffee feels alive — and highly sensitive people are often the ones capable of sensing that life most clearly.

As for daily coffee habits, I personally believe that highly sensitive people shouldn’t drink coffee merely for energy or social belonging. Coffee should offer a controllable, warm, layered, and non-aggressive sensory experience. Ideally, it’s best enjoyed in the morning, giving the body an entire afternoon and evening to metabolize even small amounts of caffeine.

And above all, trust your own feelings.

If a certain coffee leaves your mind buzzing, your stomach tight, or your finish bitter and drying, that doesn’t mean you “don’t understand coffee.” It simply means your nervous system is helping you choose what truly suits you.

And to all the “angels” scattered quietly throughout this world — yes, I genuinely believe highly sensitive people are the ones repairing the cracks of the world — you deserve a cup of coffee that feels like a peaceful afternoon: gentle, profound, and never rushing you.

Take your time.

You’re doing beautifully.

Why “Coffee Milk” Is Taking Over Cafés: The Hidden Science Behind 4.0 Milk and Better Lattes

 Have you noticed an interesting trend lately? More and more dairy brands are launching what they call “milk for coffee.” In many ways, this reflects the growing segmentation of the modern food industry — moving away from the old idea of “one milk fits all” toward highly specialized categories like coffee milk, milk tea milk, kids’ milk, fitness milk, and beyond. The dairy industry’s aggressive move into the coffee space is far from accidental imitation; it’s a strategic convergence driven by deep market insight. When coffee meets milk, it creates a sensory experience that feels almost destined, and throughout that process, the quality of the milk can dramatically shape the flavor and texture of the final cup.

Whenever I visit coffee shops, there’s one detail I always pay close attention to: the milk they choose for espresso drinks. Setting aside plant-based alternatives designed for lactose intolerance or niche flavor profiles, today I want to focus purely on traditional dairy milk. If you really observe carefully, you’ll realize that the evolution of coffee flavor is deeply tied to the upgrading of milk products themselves. From both personal observation and a broader market perspective, I want to talk about this invisible battle happening behind the scenes — a quiet revolution of liquid protein competing to redefine mouthfeel.

I’d like to explore this topic from both sides: the perspective of coffee professionals and that of dairy manufacturers. Once you understand the bigger picture from this third-person perspective, every latte you drink starts to feel different. You begin to realize how much product innovation and extraction refinement are hidden behind a single cup. Maybe after reading this article, the latte in your hand will taste even better — who knows? Haha.

If you search for “coffee milk” on Chinese e-commerce platforms, you’ll quickly notice that many dairy products prominently advertise a “4.0” concept in bold lettering on their packaging. So what exactly does “4.0” mean, and why is it so closely connected to coffee applications?

This isn’t just marketing hype. It’s actually a form of technical product adaptation. The “4.0” refers to the core nutritional metrics of milk: protein and fat content. Traditional fresh milk typically contains around 3.0–3.3g of protein and 3.5–3.8g of fat per 100ml. Under high-temperature steaming and when combined with espresso, this type of milk can produce coarse foam that dissipates quickly, negatively affecting texture integration and creating a rougher mouthfeel.

Milk with protein and fat levels above 4.0g, however, behaves very differently. During steaming, it creates finer, more stable microfoam with a texture closer to cream. The higher fat content also enhances sweetness and smoothness, helping balance the bitterness of dark roasts or the acidity of lighter roasts, ultimately creating a more harmonious cup of coffee.

From the perspective of coffee professionals, this shift makes perfect sense. As specialty coffee culture continues to grow, consumers have become increasingly capable of distinguishing whether “the milk in a latte is good or not,” and many are willing to pay a premium for better texture and flavor. Since profit margins on coffee beans themselves have gradually narrowed, cafés have started upgrading milk quality as a way to increase average ticket prices — such as charging an extra few yuan for premium “ice blog” milk substitutions.

From the dairy industry’s point of view, the logic is equally clear. Traditional white milk markets have become highly competitive, with slowing growth and intense price wars. Coffee, on the other hand, represents a high-margin, fast-growing niche market. This has created an interesting shift: coffee shops are no longer passive buyers of dairy products. Instead, they’ve become collaborative partners helping define product standards together with dairy companies. In that sense, the emergence of “4.0 milk” is the direct result of highly targeted industry specialization meeting real consumption scenarios.

At the same time, consumer habits themselves are undergoing a major transformation. People aren’t necessarily drinking less milk — they’re simply consuming it differently. The milk may now come through bubble tea or a latte instead of a glass at breakfast. In some ways, it almost feels like dairy brands adopted a “if you can’t beat them, join them” mentality. Rather than being displaced by trendy beverages, they repositioned themselves upstream in the supply chain as an essential component of those drinks.

In a typical latte, milk accounts for nearly 80% of the beverage. That means dairy is no longer just a supporting ingredient; it has become one of the core variables determining flavor, texture, quality, and even cost. Since café consumers are predominantly female, and lattes consistently rank among the highest-selling menu items, milk has become more important than ever.

Coffee bean flavor itself is constrained by factors like origin, terroir, roasting, and extraction. To be honest, some aspects are simply “genetically determined” by the bean, leaving limited room for adjustment. Dairy products, however, offer tremendous flexibility. By modifying protein and fat content, incorporating enzymatic processing, or adding functional ingredients, milk can evolve from simply “tasting good” into a highly engineered flavor and texture tool.

In certain niche applications, even subtle differences in milk composition can dramatically change the foam structure and integration within a latte. To some extent, major dairy brands are now actively defining the texture standards of modern milk-based coffee.

One of the most memorable examples I encountered happened while visiting a café in Hangzhou not long ago. I noticed the owner had a clever little trick for making flat whites: he used Wei Chuan Rich Milk 4.0 combined with about 15 grams of rice milk. It was an unexpectedly elegant idea. The result was a subtle boost in sweetness that complemented darker roasted beans beautifully, yet it remained incredibly delicate — nothing felt overpowering or artificial.

That experience really highlighted just how influential milk can be in shaping both the flavor and tactile experience of milk coffee.

At the same time, I’ve also visited cafés where the balance wasn’t handled properly. If the cup size, milk ratio, and foam structure aren’t carefully controlled, the drink can easily become overwhelmingly rich or “milky,” almost to the point of feeling greasy. Unless you’re specifically making a flat white with tighter foam and smaller volume control, there’s definitely a risk of overdoing it.

Some of the “4.0” milk products on the market achieve their higher protein levels through membrane filtration or evaporation concentration techniques, which can create a heavier, denser mouthfeel that easily overshadows the flavor characteristics of the coffee beans themselves.

UFO Coffee Dripper Review: The 80° Cone Design That Boosts Sweetness & Clarity

 This UFO-shaped dripper might look like a gimmick at first glance, but its design is anything but superficial. It actually rethinks the fundamental logic of the classic conical dripper—and that genuinely caught my attention. I’m planning to dive deeper into its design principles and extraction benefits before deciding whether to pick one up and share my hands-on experience with you all.

At its core, the UFO dripper still follows a conical structure. However, both its opening angle and overall form differ significantly from most standard cone drippers. The most notable shift? It moves from what we typically think of as a V60 to something closer to a “V80.” Yes—an 80° cone angle. This steeper angle accelerates water flow. On top of that, instead of the usual raised internal ribs, it features recessed ribs. The combination of an 80° cone and concave ribbing works like a double boost: it concentrates water flow, reduces channeling, and ultimately leads to a more even extraction—bringing out brighter acidity and more expressive aromatics in the coffee.

Let’s break it down further.

At first glance, the dripper appears short and wide. If you look closely at the walls, you’ll notice it’s made of thick ceramic—but not with uniform thickness. The upper wall is actually about 23.7% thinner than the lower section. The rim flares outward like a flying saucer, creating a wide lip. This isn’t just aesthetic—it serves a functional purpose. During brewing, heat naturally rises. The space formed between the wide rim and the top of the filter paper allows steam to escape more efficiently, preventing it from accumulating and condensing back into the brew. This helps maintain airflow above the dripper, stabilizing extraction temperature and avoiding overheating in the upper coffee bed—which can otherwise lead to a “steamed” or overcooked taste.

Now, consider this: when the base diameter and dose remain constant, increasing the cone angle spreads the coffee bed wider and reduces its vertical height. This shortens the distance water travels through the grounds, increases the surface area for flow, and lowers resistance per unit area—resulting in a faster overall flow rate. The outcome? A cup that leans toward higher sweetness, lower bitterness, and a cleaner, more refreshing profile.

But there’s a trade-off. A shallower bed combined with faster flow can lead to under-extraction if left unchecked. That’s where the recessed ribs come into play. They prevent water from taking shortcuts along the edges and ensure it passes through the coffee bed. In other words, they act as a forced flow-guidance system, compensating for the reduced contact time caused by the shallower bed.

This type of concave rib design isn’t entirely new—it has appeared in several classic drippers—but compared to the raised spiral ribs of a traditional V60, it offers some distinct advantages. The recessed vertical grooves create a physical buffer zone between the filter paper and the dripper wall. In conventional designs, water can easily slip along the wet filter paper and bypass the coffee bed (a phenomenon known as bypass flow). Here, those grooves “catch” the water and redirect it downward. By blocking edge channels, the design forces water to pass more evenly through the center of the coffee bed, significantly reducing channeling and improving extraction consistency.

This also means the dripper is more forgiving. Even if your pouring technique isn’t perfect—or if your stream hits the edges—the flow system helps guide the water back on track.

As a result, this dripper shows clear advantages when brewing light roasts or coffees with pronounced floral and fruity notes. Think Geisha or Yirgacheffe: you can expect lifted aromatics, lively acidity, and a clean finish with minimal bitterness or woody astringency—even toward the end of the brew.

That said, there’s one important caveat: this dripper is not compatible with standard filter papers. It requires specially designed UFO filters. Interestingly, these filters aren’t made from traditional paper pulp—they’re composed of a food-safe blend of lyocell and PLA. This means you can skip pre-rinsing without worrying about papery off-flavors.

There are two types of filters: Type A and Type F. “F” stands for fast, while “A” stands for average. Compared to A, the F filter is larger. Type A is designed to produce a brighter, more balanced cup, and is generally sufficient for standard use. Type F, on the other hand, enhances body and works well for hybrid immersion-drip brewing methods.

The manufacturer also provides recommended brewing parameters:

For Type F filters (baseline):

• Grind size: 800–1100 μm (Comandante C40: 22–27 clicks)
• Ratio: 15g coffee to 250g water (1:16.67)
  • For more body, increase dose to 16.6g (1:15)
• Water temperature: 92°C ±4°C
  • Dark roast: ~88°C
  • Very light roast: up to 96°C

Pouring structure:

• 00:00–01:00: 50g (circular pour)
• 01:00–01:30: 50g (circular)
• 01:30–02:00: 50g (circular)
• 02:00–02:30: 100g (center pour)

For Type A filters (baseline):

• Grind size: 1000–1300 μm
• Ratio:
  • 13.5g : 225g (lighter, tea-like body)
  • 15g : 225g (juicier mouthfeel)
• Water temperature: 92°C

Pouring structure:

• 00:00–00:30: 45g (circular)
• 00:30–01:00: 45g (circular)
• 01:00–01:30: 45g (circular)
• 01:30–02:00: 45g (center)
• 02:00–03:30: 45g (center)
• Total brew time: under 3.5 minutes

For iced pour-over (Type A):

• Grind size: 1100–1400 μm
• Ratio: 20g coffee : 200g water
• Water temperature: 92°C

Pouring structure:

• 00:00–00:30: 50g (circular)
• 00:30–01:00: 50g (circular)
• 01:00–01:30: 50g (circular)
• 01:30–03:00: 50g (center)

Brew hot, then pour directly over a glass filled with ice and enjoy.

They’ve also released a UFO Dripper V2 made from durable, heat-resistant Tritan, which is better suited for immersion-drip hybrid brewing with Type F filters. I won’t go too deep into that here.

The brand has also collaborated on various limited-edition releases, including filter papers with Spain-based SIBARIST and handmade ceramic drippers with multiple studios. One standout collaboration, in my opinion, is with MK Studio—a Copenhagen-based ceramics studio founded by Magdalena and Michal, a husband-and-wife team. Combining Michal’s background as a chef with Magdalena’s expertise in ceramics, they blend culinary sensibility with artistic craftsmanship. Their take on the UFO dripper is more expressive and artistic, with each color limited to just 60 pieces worldwide—though they’re likely sold out by now.

To wrap it up: from concept to execution, this dripper feels thoughtfully designed and logically consistent. It’s best suited for intermediate to advanced brewers who have some control over their technique. If you’re looking to highlight delicate notes like fruit acidity and florals—and push your pour-over experience to the next level—this might just become your new favorite brewing “toy.”

Smart Dripper Coffee Guide: Immersion vs Pour Over Brewing

 In recent years, we’ve seen a clear trend in professional coffee competitions: brewing methods that combine pour-over (percolation) and immersion extraction are becoming increasingly popular among competitors. It’s not uncommon to see contestants using what’s often called a “smart dripper”—a hybrid brewing device—on the competition stage. The two most iconic examples are the Hario Switch and the Clever Dripper.

We can group these devices under the umbrella term “smart drippers.” A few years ago, they had a moment of hype among coffee enthusiasts. But along with that popularity came skepticism—some people even argued that these “smart” brewers weren’t all that smart. So let’s take a deeper look: what exactly is a smart dripper, and why is it considered a hybrid brewing method? What is it really combining?

A smart dripper is essentially a filter brewer equipped with a valve system at the bottom. Its brilliance lies in the control it gives you over the flow of coffee. When the valve is closed, water and coffee grounds remain in full contact, creating an immersion-style extraction similar to a French press. When the valve is opened, the brewed coffee passes through a paper filter and drips down, much like a traditional pour-over such as the Hario V60.

This dual functionality is the essence of hybrid brewing: a seamless combination of immersion and percolation. It allows baristas to switch between extraction styles within a single brew, giving them precise control over flavor development.

So why are competition-level baristas putting their trust—and their scores—into these devices?

The answer comes down to solving two major pain points. In pour-over brewing, water flows through the coffee bed, extracting bright acidity, layered complexity, and delicate floral and fruity notes, resulting in a clean and light-bodied cup. Devices like the V60-style smart drippers are particularly good at highlighting these qualities.

However, when you introduce an immersion phase, the grounds stay fully saturated, leading to a more even extraction. This enhances body, smoothness, and sweetness, while also improving consistency. In other words, hybrid brewing captures the best of both worlds.

This method allows you to create a cup that is both clean and rich, both bright and sweet. For example, with naturally processed coffees—known for their complexity—baristas often design multi-stage brewing profiles. A common approach is to start with immersion to build sweetness and depth, then switch to percolation to increase clarity. The early pour-over phase extracts the bright aromatics, followed by a longer immersion phase to draw out deeper sweetness.

Another advantage, especially in competition settings, is forgiveness. The immersion stage makes extraction more even and tolerant of small variations in grind size or pouring technique, reducing the risk of inconsistency.

Some competitors even push this further with precise temperature profiling. For instance, they might begin with water at 96°C to maximize sweetness and aroma, then drop the temperature to around 80°C toward the end to tighten the finish and clean up the aftertaste. These profiles are often the result of extensive testing—sometimes dozens of iterations—where even small adjustments can define the final cup.

Others focus on time and extraction staging. One strategy is to use the first 40% of the water for percolation to quickly extract aromatics, then switch the remaining 60% to immersion, letting the coffee steep for over two minutes to build sweetness and body. This creates a cup with more distinct flavor layers.

For everyday coffee drinkers or café service, the real beauty of these hybrid brewers is accessibility. You don’t need to be a world champion to brew an 80+ point cup. What used to be complex technique is now simplified into a single switch—offering both consistency and the tactile pleasure of manual brewing.

Among these devices, the Hario Switch has seen a resurgence in popularity in recent years, especially with its expanded range of colors. It retains the iconic spiral rib design of the V60, which helps enhance flavor clarity. Available in glass and ceramic versions, it offers a premium feel, along with a silicone base, stainless steel ball valve, and a side lever that allows you to switch between immersion and drip modes with ease.

The Clever Dripper, on the other hand, features a plastic body with a conical design and a bottom-release valve that opens when placed on a cup. It’s typically more affordable and highly durable, though it doesn’t allow the same level of real-time switching during brewing as the Switch.

So how can you make the most of these hybrid brewers at home?

While they can be used purely for immersion or purely for pour-over, the real magic lies in combining both. One method I personally enjoy is the reverse-addition immersion approach: close the valve, pour in all the hot water first, then add the coffee grounds. After stirring, let it steep for about four minutes before opening the valve. This method promotes even extraction and enhances sweetness—especially effective for naturally processed African coffees, bringing out complex fruit and floral notes.

Another approach is a three-stage method: immersion → immersion → percolation. Start with a 30-second bloom, followed by a one-minute immersion phase, and finish with a final pour that drains through. This produces a smooth, juice-like cup with balanced sweetness and clarity—great for everyday beans.

The true charm of the smart dripper lies in how it breaks down the traditional divide between immersion and pour-over. It gives baristas the freedom to design brewing profiles based on the unique characteristics of each coffee.

Whether it’s a competition-level “recipe” or a beginner-friendly one-switch brew, these devices make it possible to create an excellent cup of coffee.

And that’s the point worth remembering:
great coffee isn’t reserved for experts—anyone can brew a delicious cup.

The Coffee Generation Gap: Gen Z is Brewing at Home—Who’s Even Going to Cafes Anymore?

 From the audience profile of Pu’er coffee, most consumers fall within the 25–35 age range. This group also represents a major driving force in the domestic consumer market. As coffee culture continues to spread and gradually becomes part of everyday life, home coffee equipment is constantly evolving and upgrading alongside it. With the growing accessibility of home setups—such as espresso machines with precise temperature control and high-quality grinders—as well as specialty coffee beans, recreating a cup at home that “rivals a café” has become entirely achievable. From my own observations, many coffee enthusiasts around me are not only café-goers, but also regularly brew coffee at home. Most of them own fairly complete brewing setups, and some have even installed commercial-grade equipment in their homes.

This leads us to an unavoidable question: when my “kitchen” understands my taste better than the café downstairs, and when AI can even pour latte art for you, how much is the “human touch” of a café still worth? When coffee machines begin to “think,” what exactly can cafés continue to sell? In reality, many people’s coffee consumption habits are already shifting—from “going out for coffee” to “making it at the table.” Data shows that Gen Z consumers aged 18–24 are particularly drawn to fruit-based and tea-infused coffee drinks. They are willing to pay premiums for collaborations, view home coffee as a form of “social currency,” enjoy DIY, and love sharing their creations on social media. They also tend to favor capsule machines and convenient solutions. Those aged 25–39, the backbone of the workforce, typically consume one to three cups per day and pay close attention to origin and roasting techniques. Among this group, home coffee users are growing rapidly, with a 45% increase in the adoption of fully automatic machines—reflecting a pursuit of balance between quality and efficiency. Consumers aged 35–49 tend to prefer low-caffeine and health-oriented products, often bringing their children along to experience coffee culture, and their average spending per order is about 20% higher than the market average. Meanwhile, among those over 50, around 70% prefer low-caffeine coffee, show strong loyalty to traditional espresso, and favor user-friendly smart machines.

It’s clear that many people are considering investing in home coffee setups. For coffee lovers, the demand for home equipment is essentially about an “externalized sense of satisfaction.” The emotional reward of making a cup yourself—of crafting a latte art design—is fundamentally different from simply buying a cup every day. Younger consumers, in particular, want to enjoy a café-level experience at home, prioritizing factors like refrigeration, convenience, customization, and craftsmanship. In the past, many of my colleagues would bring a bottle of homemade cold brew to the office during summer. Whatever they didn’t finish could be stored in the office fridge—because, quite simply, “what you make yourself just tastes better.”

Even so, what value do cafés offer today? For those who can already make a decent cup at home, are they still willing to walk into a café? Speaking for myself, while part of my motivation for visiting cafés is to gather material for writing, I still ultimately serve my own needs first. Even though I have a fairly complete commercial-grade setup at home, I still enjoy going to cafés. In fact, the value of cafés is evolving. You’ll find that most cafés have shifted from being purely functional places that “serve a good cup of coffee” to becoming experience-driven spaces that offer layered, multifaceted value.

From a product standpoint, although the number of home coffee users is growing, those willing to invest over $1,000 in a machine remain a minority. When it comes to espresso, the difference in equipment quality truly embodies the principle of “you get what you pay for.” Even high-end home machines struggle to replicate the results of top-tier commercial espresso machines worth tens of thousands of dollars, paired with premium grinders and supported by tightly controlled roasting and extraction environments. In this sense, cafés serve as the most accessible “laboratories of ultimate flavor” for the average person. By simply visiting a café, you can experience the synergy of these high-end tools—without having to invest in them yourself.

This is also why competition among cafés has become so intense. When home coffee can reach an “80 out of 100,” cafés must aim for “95 or higher”—especially given how many cafés there are. Another important factor is variety. Most home users are unlikely to invest in equipment like cold drip towers or complex cold brew systems just for one or two cups, nor can they realistically maintain a selection of a dozen different beans from various regions and processing methods. Cafés effectively offer a “low-cost gateway to exploration.”

There is, however, one core value of cafés that will never disappear: their role as a space of emotional and psychological belonging. This is not just an abstract concept—I deeply believe in it. My own journey began with a love for cafés, and only later did I start to explore and study coffee itself. A café is a place of escape and transition—a “third space.” Home is the “first space,” filled with responsibilities and daily routines; the office is the “second space,” defined by pressure and KPIs. The café, by contrast, offers a “bounded public environment.” Here, you can be surrounded by people without feeling lonely, while still maintaining anonymity and freedom. This kind of “loosely connected” social experience is something the home cannot provide.

Think of neighborhood cafés: after work on weekdays, waves of customers still come in. They’re not just there for coffee—they want to sit for a while before heading home. They might strike up conversations with strangers, unwind, or simply enjoy the sensory journey—from the chime of the doorbell upon entering, to the ambient music, to the sight of a barista behind the counter, to the delicate coffee cups. This entire sequence creates a subtle sense of “self-reward,” and that ritualistic feeling is a vital part of the consumption experience.

Another important function of cafés is their role as micro cultural hubs. Many café owners host cupping sessions, latte art workshops, or even small exhibitions, connecting local creative communities. This kind of real, human interaction is something that “online socializing” can never fully replace. Ultimately, a café’s core competitiveness no longer lies in whether its coffee tastes better than what you can make at home, but in whether the space itself draws you in—and whether the barista and the community atmosphere give you a reason to return.

From Estate to Producer: The Rise of Fidel Huancas and Peruvian Specialty Coffee

 For those of you who love “bean hunting” as much as I do, you may have noticed an interesting shift: many coffees are no longer defined primarily by the name of an estate, but instead by the individual producer behind them. One producer who left a particularly strong impression on me—and remains one of my favorites—is Pepe Jijón from Ecuador. I’ve previously written about his unique Wave Washed Geisha processing method, along with a detailed profile and tasting notes of his coffees.

This shift reveals something deeper within the specialty coffee industry. It marks a transition from emphasizing the “estate” to recognizing the “producer.” In a sense, the pursuit of terroir has evolved into a respect for human value.

Traditionally, a well-known estate signified excellent terroir, mature farming practices, and reliable processing capabilities. It served as a guarantee of quality and consistency—consumers trusted that any coffee from that estate would meet a certain standard. But as specialty coffee has matured, people have begun to realize that even within a single estate, different plots can produce dramatically different flavor profiles. Labeling all of them under one estate name can actually blur their individuality.

What truly determines the quality of coffee is the decisions and craftsmanship of the people involved—the growers, pickers, and processors. The estate is merely the stage; people are the soul.

You can see this clearly in high-end coffee competitions. Award lists now often highlight not just the estate, but also the producer’s name. When a smallholder farmer wins a top prize at the Cup of Excellence, their name becomes synonymous with quality. Emphasizing the producer is also a natural outcome of the specialty coffee industry’s push for traceability. Consumers want to know who grew their coffee. This recognition allows producers to receive the credit—and compensation—they deserve, while also enabling direct trade relationships.

In many cases, the producer’s name has become a more precise indicator of both quality and flavor. That’s why so many coffees today are marketed under the producer’s name rather than the estate.

Today, I want to talk about Peru as a coffee origin.

To be honest, Peru has always carried a bit of a “potential risk” in my mind. It doesn’t shine as brightly as neighboring countries like Brazil or Colombia. But when you come across a truly good Peruvian coffee, you’ll find a beautifully balanced and elegant cup.

Coffee production in Peru is dominated by smallholder farmers, most of whom cultivate less than two hectares of land. Due to economic constraints, many farmers cannot afford chemical fertilizers or pesticides—ironically making Peru a stronghold for organic cultivation. Around 70% of the country’s production is Typica, with smaller amounts of Caturra, Bourbon, Pache, and Geisha. Washed processing is the dominant method, resulting in clean cups with bright acidity.

Overall, Peruvian coffees may not be explosively vibrant at first sip, but the more you taste, the more you realize they have everything they need. There’s an understated elegance—refined acidity paired with a full, satisfying sweetness that reflects the terroir of the Andes. In higher-altitude regions especially, the flavor complexity becomes more pronounced, often revealing floral notes, tropical fruits, and melon-like sweetness. For many coffee enthusiasts, Peru is a hidden treasure waiting to be discovered.

Today’s coffee comes from Assembly Coffee in London, featuring beans produced by Fidel Huancas from Peru. Through this coffee, I’d like to share both his story and the flavor profile it delivers.

Fidel Huancas is a third-generation coffee producer from the Chirinos district in Cajamarca, Peru. He manages a 1.5-hectare farm called La Esperanza—“Hope”—a name that reflects his aspiration to produce exceptional coffee and become one of the region’s top producers. The coffee I’m discussing today comes from this very farm.

After graduating from high school in 2004, Fidel began his journey as a coffee producer, inheriting land from his father. By the age of 21, he had started his own family and, through hard work, purchased an additional two hectares of land. In 2017, he traveled to Costa Rica for an internship, where he learned new agricultural techniques that he later implemented on his farm with great success.

His dedication, passion, and attention to detail have driven significant progress in his coffee production. Like many farmers in the region, he represents a new generation of producers elevating coffee quality—supported by progressive cooperatives and local export organizations.

I noticed that his newer farm, Aroma del Corazón (purchased in 2022), ranked 21st in the 2024 Cup of Excellence Peru competition. Located at 1,900 meters above sea level, it shares a similar high-altitude environment with his original La Esperanza farm at around 1,950 meters. Clearly, his coffees are rooted in high-elevation terroir.

Over the past two decades, Fidel has relentlessly pursued quality, earning recognition along the way. Coffee has allowed him to provide a better life for his family, including funding the education of his three children. He is personally involved in every step of production—from hand-picking ripe cherries to overseeing processing at his farm’s washing station.

His process begins with careful hand selection, followed by flotation to remove defective cherries and debris. The beans are then fermented in small tanks, thoroughly washed to remove mucilage, and dried under controlled conditions. This meticulous washed process results in a clean, crisp, and juicy flavor profile.

The coffee I tasted is a blend of Caturra and Pache—two varieties commonly grown in Peru. Both are Arabica cultivars originating from Central and South America. Caturra, a natural mutation of Bourbon, is known for its high yield and adaptability, while Pache, a mutation of Typica, is prized for its exceptional flavor potential.

Together, they create a cup with bright acidity—often reminiscent of citrus and lemon—balanced by notes of nuts and chocolate. The overall profile is elegant and complex, with a rich mouthfeel. Caturra brings liveliness and structure, while Pache contributes a more subtle, refined sweetness. If Caturra is the expressive performer, Pache is the quiet master—less productive, but deeply captivating for those who appreciate its nuance.

As for the roaster, Assembly Coffee was born from the idea of “collective intelligence.” Back in 2014, a small team from Volcano Coffee Works gathered leading independent café and restaurant owners across the UK to explore a key question: how can a roaster best serve its role within the specialty coffee value chain?

After six months of in-depth discussions, they developed a blueprint for a customer-focused, innovative, and flexible roasting company—thus, Assembly was born.

Assembly Coffee represents the cutting edge of London’s specialty coffee scene. One line from their website stood out to me:

“The roastery would only source coffees that met the needs of its customers and never for its own gratification.”

Their roasting style reflects this philosophy. They favor light to medium roasts, aiming to precisely highlight origin characteristics, processing nuances, elegant acidity, and natural sweetness—rather than creating flavor through roast level.

If you ever visit London, I highly recommend stopping by their Brixton headquarters, housed in a converted 19th-century fire station. You’ll also find their beans served in many of the city’s top cafés.

As for the cup itself—

The dry aroma immediately reminded me of dried apricot, accompanied by subtle white floral notes. The overall fragrance is balanced, gently sweet, and very comforting.

After brewing, the flavor opens up into notes of stewed fruit, warm baking spices, and the juicy sweetness of blood orange. The wet aroma especially evokes something like a “fruit soup”—that slightly cooked, lightly oxidized fruit character. The profile leans bright yet structured, with a juicy texture and layered fruit aromatics.

To be honest, finding a Peruvian coffee at this level of flavor is already something special.

As I sat at home in Hangzhou, sipping this coffee roasted in London and grown by Fidel Huancas in Peru, I couldn’t help but feel that this kind of “global movement” is one of coffee’s most romantic expressions.

Coffee producers embody both human skill and spirit. They represent real individuals, families, and the result of hard work and accumulated wisdom. In today’s era of smallholder farming and refined processing, they have become the true core of both quality and storytelling.

When a coffee is named after its producer, it sends a clear message: this is not just a product of a place—it is the work of a real person, someone who has poured their life into it.

And that is something worth respecting—and appreciating.
