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.

What Is Golden Honey Process Coffee? Specialty Coffee Processing Explained (White, Yellow, Red & Black Honey)

 Just recently, while attending a coffee tasting event—what we often call a “coffee cupping banquet”—I happened to hear the term “Golden Honey Process.” Most of us are already familiar with names like White Honey, Yellow Honey, Red Honey, and Black Honey when it comes to coffee processing methods. But what exactly is Golden Honey?

For a moment, it made me reflect on how new terminology constantly appears in certain industries today. These new terms often make people both curious and cautious. Are they the result of genuine technological innovation, or simply clever marketing? It struck me that this phenomenon is actually worth discussing within the specialty coffee world. So today, I’d like to share some of my observations and thoughts—and of course, feel free to join the conversation in the comments.

The charm of specialty coffee lies in its spirit of innovation and continuous learning. To some extent, the appearance of new professional terms and vocabulary in the industry is a good thing. After all, it means people are trying new ideas. These terms are often the result of both technical experimentation and marketing needs working together. That said, we should also approach them with a certain level of critical awareness rather than accepting everything at face value. My reflections today are simply based on this personal experience, and coffee processing methods are far from the only area where new terminology keeps emerging.

At its core, coffee processing is fundamentally about fermentation. During this stage, there are countless variables involved—temperature, humidity, time, microorganisms, shade, stirring frequency, and more. A farm or processing station might make subtle adjustments to traditional methods such as honey processing or anaerobic fermentation. For example, they might change the duration of anaerobic stages, alter the percentage of mucilage left on the beans, or modify the materials used in drying beds. In order to distinguish these slight variations from standard terminology, producers sometimes give the process a more specific and appealing name.

The coffee I encountered at the event was a Geisha from Costa Rica’s Finca La Bandera, processed using what they call the Golden Honey method. However, it’s important to understand that “Golden Honey” is not a globally standardized processing term. Instead, it is more of a marketing-level name proposed by a particular farm, processing mill, or green coffee trader. To truly understand what this means, we need to briefly revisit what honey processing itself actually is—and what the color labels added before the term represent.

Honey processing is a method that sits somewhere between natural (dry) processing and washed processing. The key step involves removing the outer skin and pulp of the coffee cherry while leaving some of the sticky, sugar-rich mucilage attached to the bean. The beans are then fermented and dried with this mucilage still present.

Different honey processes are categorized based on how much mucilage is retained and how the beans are dried:

• White Honey: Most of the mucilage is removed. Drying happens quickly, and the flavor profile is closest to washed coffee—clean and bright with crisp acidity.

• Yellow Honey: Some mucilage is retained. Beans are dried in the sun and turned regularly, producing moderate sweetness and body.

• Red Honey: More mucilage remains. Drying occurs slowly under shade or reduced sunlight, with less frequent turning, resulting in stronger sweetness, fuller body, and more noticeable fermentation notes.

• Black Honey: Nearly all mucilage is left on the beans. Drying happens extremely slowly under heavy shade with minimal turning. This produces the most intense flavors and body, often with dark fruit and spice notes—but it also carries the highest risk during processing.

  

So where does Golden Honey fit in?

In terms of technique, it can be understood as a finely calibrated point somewhere between Yellow Honey and Red Honey. Essentially, the farm has chosen to define what they consider an “ideal balance” within that range and has given it a distinctive name. By creating a new term within a familiar framework, producers can communicate the idea that their process represents a more refined and carefully controlled version of honey processing. In other words, they are signaling to consumers that this coffee is crafted using more meticulous techniques to achieve a particularly clean, sweet, and high-quality cup.

Golden Honey typically implies a more elegant sweetness and a cleaner fermentation profile, aiming to locate a superior or distinctive flavor point within the traditional honey-processing spectrum. At the moment, the term is almost exclusively associated with Finca La Bandera in Costa Rica. When people mention Golden Honey, they are very likely referring to beans from this particular farm.

Interestingly, I’ve also seen producers in Yunnan, China use terms such as “Golden Robe Honey Process,” which functions in a similar way. These names are essentially designed to create memorable branding and differentiation. In today’s highly competitive specialty coffee market, terms like natural, washed, and honey processing have already become basic vocabulary. When a new and distinctive name appears, it can instantly capture consumers’ attention and help a coffee stand out during green bean auctions or retail sales.

Of course, we can reasonably assume that a process like Golden Honey probably does involve more refined control within the existing honey-processing framework. For instance, the producer may aim to keep the mucilage at a precise “sweet spot,” implement strict drying management, and use slower drying at lower temperatures to prevent overly rapid sugar fermentation that could produce harsh acidity. The goal would be to develop a cleaner, more structured sweetness.

There may also be greater attention to even drying, including careful timing and frequency when turning the beans.

From a consumer’s perspective, however, it’s important to maintain a stable framework of knowledge. With solid fundamentals in mind, we can better evaluate any new terms that appear in the market. This helps prevent us from falling into certain consumerism traps. While innovation can certainly spark curiosity and encourage exploration, new terminology can also confuse consumers, making it difficult to determine whether something represents real innovation or simply old wine in a new bottle.

When tasting coffee, we should always remember that the most reliable judge is our own palate. When encountering a new term like “Golden Honey,” we can ask ourselves:

• Does this coffee truly taste different from other honey-processed coffees I’ve had?

• Is its sweetness, acidity, body, or clarity genuinely distinctive?

  

On the one hand, we should recognize that the industry is evolving rapidly and welcome innovation supported by transparent information. Such innovation reflects progress in coffee farming and provides new ways to communicate flavor experiences. On the other hand, we should remain cautious of names that are overly poetic, difficult to trace, or unwilling to explain their processing details. True innovators are usually happy to share the specifics of their techniques because they want people to appreciate and spread the value of their work.

After all, the definition of Golden Honey can vary from farm to farm, and there is no absolute standard. What we can develop instead is our own standard: no matter how beautiful the name sounds, let the flavor in the cup be the final judge. There’s no need to mythologize the terminology—always trust your taste buds to verify the most authentic experience.

What Makes a Great Coffee Roaster? A Deep Dive into the Art & Science of Coffee Roasting

 Among coffee professionals, there is a group of true “behind-the-scenes heroes.” They may not be great talkers, many of them lean toward being introverts, and they tend to work with rigor, precision, and an almost obsessive attention to detail and data. In my eyes, they are among the most technically skilled people in the coffee industry: coffee roasters.

If I had to sum up their work in one sentence, it would be this:
“I am not the creator of flavor—I am a carrier of flavor.”
They are the ones who allow every coffee drinker to experience the unique character and terroir of different origins. In that sense, roasters play an irreplaceable role.

Looking back, I’m surprised that despite nearly ten years of daily writing, I’ve never written a dedicated piece about coffee roasters. Recently, as I’ve been testing beans from different roasters, I’ve found that I can genuinely sense their thinking through their roasting styles. This quiet, almost invisible form of dialogue has deepened my appreciation and respect for roasters—and that’s why I want to share my personal definition of what makes an outstanding one.

In the early years, whenever I attended coffee expos, I loved wandering through different halls to watch competitions. I’d marvel at the complexity of latte art designs, or cheer for the confident performances in barista championships. The atmosphere was always intense and electrifying. But when it came to roasting competitions, the scene was entirely different—almost silent. Roasters stood quietly by their machines, roasting beans, surrounded only by the rich, toasty aroma of freshly roasted coffee. Sometimes I couldn’t help but think: roasters are truly a group of people who can endure solitude.

They must integrate technical skill, sensory acuity, scientific thinking, and artistic creativity. Among all coffee-related roles, roasting may be the one that demands the most comprehensive set of abilities.

From my perspective, a solid foundation of technical knowledge is essential for any roaster. They need to be deeply familiar with the flavor profiles of different origins, varieties, and processing methods, and understand how physical characteristics such as green bean density and moisture content affect roasting outcomes. At moments like this, the old saying “Master math, physics, and chemistry, and you can go anywhere” suddenly feels very real—haha.

Roasters must also have a strong grasp of heat transfer (conduction, convection, radiation), the Maillard reaction, caramelization, and other physical and chemical processes. They need to adjust heat curves according to bean characteristics and master the logic and behavior of different roasting machines, whether direct-fire, semi-hot-air, or electric.

Beyond these technical foundations, roasters also need skills similar to those of baristas—most importantly, sharp sensory evaluation abilities. Through cupping—assessing dry and wet aroma, acidity, sweetness, body, and more—they must accurately judge roasting results and build a reliable flavor memory library.

Roasting one good batch doesn’t mean much. True mastery lies in consistency—producing good results batch after batch. We often judge a roaster by whether different batches of the same coffee taste noticeably different, which can even affect brewing parameters downstream. This shows just how critical roasting consistency really is. Developing standardized roast profiles that ensure stable flavor across batches while meeting commercial production demands is one of the core competencies of an excellent roaster.

If everything above represents “hard skills,” then the following are the “soft skills” that truly differentiate roasters at a higher level. Whether baristas or roasters, when working with a non-standardized product that people consume, the ability to flexibly apply knowledge in real-world situations becomes crucial. Being overly dogmatic or ignoring the relationships between variables can turn an inherently exploratory craft into something rigid and stagnant.

Many outstanding roasters seem to enjoy solitude—or at least quiet focus. They must possess patience and deep concentration, enduring repeated testing and adjustment. It may take dozens of trials to find the optimal roast profile for a single coffee. They spend long hours monitoring the roaster, remaining highly sensitive to details such as first crack sounds and color changes.

Whenever I visit roasting facilities and happen to see a roaster at work, even watching through a glass wall, I can’t help but feel that the end of roasting is… loneliness. It’s truly demanding work.

That said, roasters also need strong communication and collaboration skills. Some younger roasters may fall into the trap of working in isolation—focusing solely on roasting without engaging with the outside world or paying attention to industry trends. That’s a dangerous path.

Data-driven decision-making—using roast curves and cupping scores—combined with the courage to experiment with new processing methods and blending strategies is essential. With innovative processing techniques constantly emerging, roasting faces new challenges all the time. Staying informed about industry trends and understanding shifts in consumer taste preferences should be a conscious, ongoing habit.

Another crucial scenario is custom roasting. Many roasters work closely with partners to create tailored roast profiles. This customization isn’t just about exclusive blends or unique roast curves—it’s about understanding brand positioning, target flavor profiles, and balancing cost, efficiency, and flavor. In commercial roasting, profitability must also be considered. Creating a distinctive roasting style that gives a brand a recognizable identity requires roasters to be adaptable, business-aware, and committed to continuous learning.

In fact, many roasters are also “coffee hunters,” traveling to origin countries, working directly with farms, and participating in quality control from cultivation through processing.

An outstanding coffee roaster is both a scientist and a craftsman. They connect producers and consumers, serving as a core creator within the coffee value chain. Roasting is never just about making beans “done.” It is a long-term pursuit that demands dedication, passion for flavor, and a commitment to constant refinement.

This piece reflects only my personal perspective and appreciation. I can’t possibly list all the qualities that make roasters exceptional. But I do know this: they deserve far more recognition. When we taste a cup of coffee, we should try to sense the quiet effort and unspoken care of these behind-the-scenes heroes.

To all the coffee roasters out there—you are truly amazing. Thank you for being here, for filling my life with good coffee, and for enriching it in ways that often go unseen. 

Why Coffee Cups Matter: Rethinking Large vs Small in Specialty Cafés

 When we order coffee in cafés, it’s common to see certain drinks on the menu offered in “large” and “small” sizes (and let’s not bring up that brand that contradicts itself). But in reality, most espresso-based drinks already come with a naturally fixed serving size by design. Those so-called size options are often nothing more than a blunt, convenience-driven modification for consumption scenarios. I’ve long felt that cafés perhaps shouldn’t think in terms of “large” or “small” at all, but rather in terms of purpose-specific coffee cups. Today, I want to talk about where this idea comes from.

This isn’t the first time I’ve thought seriously about this topic. Early last year, when a certain brand launched an 8-ounce cortado, it sparked plenty of discussion within the industry. In the world of specialty coffee, the idea of using a purpose-designed cup for each drink reflects a deep respect for coffee culture and the consumer experience. It shifts thinking away from the purely practical logic of “big vs. small” and toward a coordinated design that balances ritual, function, and flavor. That alone makes it something worth serious consideration—and practice—within the industry.

We all know that every classic coffee drink carries an implicit functional logic in its cup design. As the specialty coffee world becomes more refined, we’re seeing more niche, highly specific products emerge to meet the needs of segmented markets. Take the cortado as a simple example. Traditionally, a cortado is served in a cup of around 130 milliliters. This volume precisely matches an espresso-to-milk ratio of roughly 1:1 to 1:2, ensuring that each sip delivers both the richness of espresso and the smoothness of milk. The drink isn’t diluted by excess volume, nor does it lose heat too quickly due to overly thick cup walls. To achieve this balance, a dedicated cortado cup is essential—it best represents the drink as intended. After all, the cup itself is one of the factors that influences flavor and presentation.

If you serve a cortado in a large cup, the extra milk or water disrupts that precise ratio. What you end up with—like an 8-ounce “cortado”—is essentially a latte, and the original design intent of the drink becomes completely blurred. A purpose-specific cup also acts as a kind of “silent language.” When I order a cortado in cafés abroad, one of my main reasons is to evaluate the shop’s level of professionalism through how the drink is presented: the cup, the integration of espresso and milk, and the resulting flavor. When the right cup is used, it often signals to me that the café truly knows what it’s doing—grounded in coffee tradition and attentive to the overall quality of the experience.

At the same time, serving coffee in dedicated cup designs guides customers toward the most appropriate way to enjoy each drink. Coffee is a multisensory experience, engaging sight (presentation), touch (how the cup feels in the hand and its temperature), smell (how aromas are concentrated), and taste (how temperature and texture evolve). The thickness of the rim affects how the liquid meets the lips; the shape of the cup influences aroma release and the stability of milk foam. Material matters too—ceramic retains heat better, while glass highlights visual layers. That’s why many cafés choose glass cups for cortados: to let customers see the beautiful interaction between milk and coffee. In fact, cortado in Spanish literally means “cut,” referring to this very interplay.

Some might argue that using purpose-specific cups for every drink would require owning an overwhelming number of different cups. For small cafés, storing and managing a dozen or more specialized cups can indeed be a significant cost and logistical burden. But this can be approached selectively or in stages. Start with the core classics—espresso, cappuccino, cortado—drinks where cup volume truly matters. Many independent cafés already think deeply about this. You can feel the care they put into matching drink volumes with the right cups. These choices go far beyond whether a cup simply looks good; they reflect careful consideration. This is a sign of specialty coffee culture maturing and becoming more refined.

One drink, one cup—much like using the proper glass for a specific wine. It’s an extension of flavor and a vessel of culture. It represents not just serving a coffee beverage, but presenting a complete coffee work. When I drink a cortado, what I taste isn’t only the precise balance of espresso and milk, but also the sense of ritual and intention behind it. And isn’t that exactly where the true appeal of professional coffee lies?

Gold Washed Coffee Explained: What Is Gold Washed Processing & Why It Tastes So Sweet

 When shopping for coffee, you may have come across a processing method labeled “Gold Washed.” We’re all familiar with one of the classic processing methods—washed—but what does the addition of gold actually mean? How is it different from traditional washed coffee? Today, I’d like to dedicate this article to exploring exactly what the Gold Washed process is.

I wanted to write this piece because I recently encountered an outstanding roaster from Kyoto at a coffee festival. They were showcasing a Red Bourbon from the Popayán region of Cauca, Colombia, processed using the Gold Washed method. That coffee left a deep impression on me—it was simply too good. Naturally, it sparked my curiosity to dig deeper into this processing style. (I’ll be sharing a full tasting review of that coffee later. I couldn’t resist and ordered two bags on the spot—no hesitation at all.)

When it comes to “Gold Washed,” there is a certain degree of producer-specific ownership to the method. By that, I mean that while the process can be learned and replicated, most of the Gold Washed coffees currently available on the market come from Santuario Project. Santuario is a professional coffee producer and exporter with farms and processing facilities in Colombia, Costa Rica, Brazil, Mexico, Ethiopia, and El Salvador.

In this article, we’ll focus on two things:

1. The overall workflow of the Gold Washed process

2. The specific advantages it brings to flavor expression

In simple terms, Gold Washed combines the strengths of both washed and natural processing. It does not strictly belong to the traditional washed category. Instead, it can be seen as a more refined, upgraded version of washed processing. The core goal is to retain the clean, bright flavor profile of washed coffees while introducing the enhanced sweetness, fruit complexity, and body commonly found in natural processing—through carefully controlled fermentation.

To better understand this, let’s compare it step by step with the traditional washed process.

The initial steps are exactly the same. First comes harvesting and flotation: only fully ripe red cherries are picked, then placed in water tanks to remove floaters, defects, and debris. Next, a depulping machine removes the outer skin and most of the fruit flesh. At this stage, the coffee beans are still coated in a sticky layer of mucilage.

Up to this point, the process is identical to traditional washed coffee. The key difference begins during the mucilage fermentation stage. In a classic washed process, mucilage-covered beans are submerged in water for underwater fermentation, typically lasting 12–36 hours. After fermentation, the mucilage is completely washed away with large amounts of clean water, followed by drying.

Gold Washed processing takes a different approach. Instead of fermenting underwater, the beans—still coated with mucilage—are placed in a dry or semi-dry environment (without full water immersion) for a longer, tightly controlled dry fermentation, which may last several days. During this time, temperature, pH levels, and humidity are closely monitored.

The reason for this method is to allow microorganisms—such as yeasts and bacteria—to interact more deeply with the mucilage, producing more complex sugars and flavor compounds. At the same time, the beans are not in contact with the full fruit mass as in natural processing, making the process more controllable and consistent in quality. This is a critical distinction: traditional washed processing prioritizes efficiency and cleanliness, often washing away much of the fermentation-driven flavor potential. Gold Washed coffees, on the other hand, manage to preserve the cleanliness of washed coffees while capturing the sweetness and expressive character typically associated with naturals.

Next comes the drying stage. In traditional washed processing, fully washed parchment coffee (still wrapped in its inner skin) is dried on patios or in mechanical dryers until moisture content reaches around 11–12%. With Gold Washed, after fermentation reaches its intended endpoint, the beans may be lightly rinsed with water, but not thoroughly washed as in traditional methods, before moving on to drying. (Perhaps this brief contact with water is why it still carries the “washed” name—just a thought.)

This gentle rinse is more important than it might sound. Its purpose is to halt fermentation, preventing over-fermentation and ensuring flavor balance in the final cup.

Because of the extended and carefully managed fermentation, Gold Washed coffees tend to develop higher sugar content, resulting in a pronounced sweetness. At the same time, they retain the hallmark bright acidity of washed coffees—often reminiscent of citrus, lemon, or green apple. The overall flavor profile is clean and well-defined, yet layered with notes of stone fruits (such as peach or apricot), berries, and sometimes even subtle tropical fruit nuances. The mouthfeel is rounder and smoother. (Honestly, I found almost all of these characteristics in the coffee I tasted—and it was incredibly satisfying.)

I really enjoy sharing these less common but thoughtfully designed processing innovations—methods that push boundaries without resorting to extreme or gimmicky techniques. Gold Washed is a great example of a modern processing approach that uses precise fermentation control to optimize flavor. It doesn’t aim to overthrow tradition, but rather to refine it.

If you appreciate the cleanliness of washed coffee but wish for more sweetness and fruit complexity, then the next time you see a coffee labeled Gold Washed, don’t hesitate. It’s absolutely worth trying.

Why You Shouldn’t Brew Small Coffee Doses with a Large Dripper (V60 Brewing Tips)

 We all know that coffee drippers usually come in two sizes—large and small. Some people assume that if a large dripper can handle a big dose of coffee, it should naturally work just fine for a smaller dose as well. So why not just buy one large dripper and call it a day?

In reality, that way of thinking isn’t ideal. Today, let’s talk about why using a large dripper to brew a small dose of coffee is generally not recommended. Hopefully, this will be helpful—and if it is, feel free to share it with your fellow coffee friends.

First, let’s clarify two concepts: how big is a “large” dripper, and how small is a “small” dose?

Let’s use the V60 as an example. A V60 labeled 02 is considered a large dripper, designed for brewing coffee for 1–4 people. A “small” dose, in this context, refers to using around 15 grams of coffee, typically brewed at a 1:15 coffee-to-water ratio.

When a large dripper is designed, it’s meant to accommodate a larger amount of coffee grounds—usually 20–30 grams or more—which naturally creates a thicker coffee bed. If you only use 15 grams of coffee in such a dripper, the risk of uneven extraction increases significantly. The result is often a cup that tastes thin, sharp, overly acidic, or bitter.

Because a large dripper has a wider diameter, a small dose of coffee spreads out into a very thin coffee bed. During brewing, hot water passes through this thin bed much too quickly, making it difficult to evenly saturate and extract all the grounds. This leads to poor control over both water flow and temperature.

One of the most serious problems during extraction is channeling. Water naturally seeks the path of least resistance, and in a thin coffee bed, it’s very easy for fixed channels to form. Most of the water rushes through these channels, while other areas of the coffee bed barely get extracted at all.

The result is the worst of both worlds:

• The areas where water channels through become over-extracted, producing bitterness.

• The areas that don’t get enough water remain under-extracted, leading to sharp acidity and hollow flavors.

As you can imagine, the final cup is far from pleasant.

There’s also a secondary factor to consider: heat retention. Large drippers—especially ceramic or glass ones—have more mass and therefore require more hot water to preheat properly. If preheating isn’t sufficient, the cold dripper will quickly absorb heat from the brewing water.

On top of that, a thin coffee bed holds very little heat on its own. Combined with the large opening of a big dripper, which increases exposure to air, the overall brewing temperature drops too quickly. Unstable water temperature and excessive heat loss often lead to under-extraction, further increasing the chances of ending up with a disappointing cup.

With a large V60 like the 02, using a small dose also makes pouring much more difficult. The steep cone angle and wide interior space mean that water can easily hit the filter paper along the sides, washing away the coffee bed or disturbing its structure. This greatly increases the likelihood of channeling.

Even if you pour very gently and precisely, getting such a thin coffee bed to bloom and expand evenly requires a high level of skill. It’s not something most everyday coffee enthusiasts can easily pull off.

That’s why, in daily brewing, it’s important to match your coffee dose to the appropriate dripper size. If you usually brew around 15–18 grams of coffee, a small dripper is the better choice—whether that’s a V60-01, a Kalita 155, or another similar model.

With a small dripper, a small dose can form an ideal coffee bed thickness. Water is forced to pass more evenly through all the grounds, the dripper is easier to preheat, heat loss is slower, and the narrower opening naturally directs water toward the center of the coffee bed. All of this makes it much easier to achieve a balanced and even extraction.

Finally, there’s one awkward but very real question to address:
What if you already own a large dripper—and only a large dripper—and still want to brew small doses?

While the best solution is still to get a properly sized small dripper, here are a few compromise strategies you can try if a large dripper is all you have for now:

• Grind finer: A finer grind increases resistance, slows down the flow rate, and extends extraction time, allowing more flavor compounds to dissolve.

• Lower the water temperature: Try brewing at around 88–91°C (190–196°F). Slightly cooler water can help prevent overly rapid extraction of bitter compounds.

• Adjust your pouring technique: Use a thinner stream of water and pour more gently and slowly.

• Use multiple pours: After blooming with a small amount of water, continue brewing with several smaller pours. Wait for the water level to drop before each pour to extend the total extraction time.

These adjustments won’t fully replace the benefits of a correctly sized dripper, but they can help improve your results until you’re able to switch to one that truly matches your brewing needs.

Why Coffee Shops Serve Flavor Cards | Coffee Tasting Notes & Third Wave Coffee Culture

 If you enjoy café hopping, you’ve probably noticed this: when you order a coffee—whether it’s espresso-based or pour-over—the barista often serves it with a small card. This card usually lists details such as the coffee’s origin, processing method, varietal, roast level, and even the story behind the region. It’s almost like an “ID card” for the coffee bean, giving you a clearer picture of what you’re actually drinking.

Sometimes, when I’m sitting in a café, I pay attention to whether other guests read these cards—or whether they take them with them when they leave. Unfortunately, most of the time, people barely notice them. Some glance at them briefly and then set them aside; almost no one takes them home. Maybe it’s because I’m a bit of an “origin nerd,” but I always want to learn as much as possible about the coffee in my cup. Occasionally, some cafés—especially when it comes to espresso—don’t disclose much information. In those cases, I’ll taste the coffee first, form my own conclusions, and then chat with the barista. If my guesses turn out to be right, it’s genuinely exciting. It feels like proof that my palate is getting sharper, and that kind of interaction is incredibly fun.

More than a decade ago, when I first started exploring cafés, I loved collecting business cards. These days, most cafés don’t bother printing them anymore, so I’ve started keeping flavor cards instead. If you look closely, many of these cards are beautifully designed and clearly made with care—the cost per card is not low at all. Taking one home as a keepsake also feels like a small gesture of respect toward the café. That’s what inspired me to write this article: why are so many cafés willing to invest in this kind of “silent conversation”? And what’s the story behind coffee flavor cards in the first place? Let’s dive in.

Since the rise of the third-wave specialty coffee movement, one core value in coffee culture has become especially important: communication and education. These days, many café owners shy away from the word “education,” as it can sound a bit preachy or condescending. But in reality, it’s a fairly neutral concept. It’s not about telling customers what they must do. As consumers, if we’re only paying for coffee to satisfy a basic craving, that feels like a missed opportunity. If we’re willing to explore the deeper culture and meaning behind it, coffee—and life—can take on much richer colors.

Flavor cards didn’t appear out of nowhere. During the second-wave coffee era, represented by brands like Starbucks, most people were drinking dark-roasted commercial coffee. The flavor profiles were largely limited to bitterness, smokiness, and chocolatey notes—fairly one-dimensional. With the third wave, however, professionals and enthusiasts began focusing on origin flavors. Different regions, varietals, and processing methods produce dramatically different profiles: floral aromas, bright fruit acidity, tea-like textures, and more. The challenge then became how to describe and communicate these complex, nuanced flavors to consumers. Simple phrases like “tastes good” or “smells great” were no longer enough. More precise language was needed.

So where do the flavor descriptions on these cards come from? And what logic do they follow? The answer lies in cupping and the flavor wheel. Cupping is the industry-standard method for systematically evaluating coffee quality. In simple terms, it involves forcefully slurping coffee with a cupping spoon so the liquid spreads across the entire palate. Throughout the process, tasters record details such as dry aroma, wet aroma, flavor, acidity, body, and aftertaste. The flavor wheel, meanwhile, was created to standardize tasting language. It organizes a wide range of aromas and flavors—from negative to positive—into a structured system. In this sense, the flavor card you receive is a simplified, practical, and personalized version of the flavor wheel. Café owners distill cupping results and flavor-wheel terminology into a small, easy-to-understand card, often using familiar, everyday flavor references to help you immerse yourself more deeply in the experience.

Why, then, are cafés willing to spend the time and money to create a specific flavor card for each coffee? One major reason is to build a bridge of communication and lower the barrier to choice. For people unfamiliar with origins and terroir, talking purely about regions and varietals can sound abstract and confusing. But words like “jasmine,” “lemon,” or “peach” immediately create a clear, intuitive image of what the coffee might taste like. Flavor cards also invite personal participation. For more advanced coffee lovers, I actually recommend tasting the coffee before looking at the card. Try to identify the flavors on your own, then check the card and see how closely your impressions match. You can even discuss it with the barista—this back-and-forth is part of the fun.

Many cafés roast their own beans, and some even source coffee directly from origin. These cafés often embrace professionalism and transparency. Using flavor cards, they share stories about the growing regions, explain the characteristics of specific varietals, and sometimes even disclose roasting curves and color values for the bean’s surface and core. In this sense, the flavor card becomes a “knowledge card,” offering as much information as possible so you truly understand what’s in your cup.

As I mentioned at the beginning, there’s also a reason cafés no longer print traditional business cards: flavor cards now serve both branding and marketing purposes. A well-designed card is a powerful branding tool, featuring the café’s logo, roast date, and origin story, all of which strengthen brand recognition. For collectors like me, this only deepens that connection. So next time you receive a flavor card at a café, think of it as the “identity code” to your coffee. Follow its guidance and embark on a small sensory adventure—and if the café allows it, don’t forget to take it home with you.
