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.

The Miniature World of Coffee: Unboxing My Kalita x BANDAI Gashapon Collection

 I’m back with another installment of my "Coffee Aroma Journey" gashapon series! Before I knew it, my collection had grown into a massive stash—I’ve easily got dozens of these little capsules by now.

I’ve always felt that gashapon culture captures the very essence of Japanese craftsmanship (shokunin). It’s more than just a toy; it’s a tiny, interactive world that offers a moment of inner peace. Through these miniatures, you get to trace a brand’s history and feel the timeless charm and evolving role of coffee culture across different eras and countries.

Today, I’m unboxing the Kalita Miniature Collection by BANDAI. This 8-piece set features Kalita’s most iconic gear: various hand grinders, the signature three-hole trapezoid drippers, filter papers, and that gorgeous copper pour-over kettle. Honestly, even without the logos, the silhouettes alone scream "Kalita." That’s the definition of a true classic.

So, let’s dive into these capsules while chatting about the stories and design brilliance behind them. I’ve realized that the world of gashapon forces me to focus on details I usually overlook—it’s a fun way to have a "self-dialogue." I guess I really am a total "gashapon head," haha!

The Kalita Legacy: Bringing Professional Coffee Home

The Kalita story began in 1958. Back then, coffee in Japan was something you only found in specialized cafes and restaurants. Kalita’s breakthrough was simplifying professional techniques so regular people could enjoy great coffee at home, quickly becoming a household name.

Many of their products are still handcrafted by Japanese artisans—take the metalwork from Tsubame City in Niigata, for example. The brand has a strong "craftsman DNA." Since their designs are often inspired by professional baristas, they strike a perfect balance between being "down-to-earth" and highly functional. They are masters at using the physical properties of copper, ceramic, and cast iron to enhance extraction flavors.

The "Origin Story": The Three-Hole Trapezoid Dripper

In this 8-piece set, the first highlight is the classic three-hole trapezoid (or fan-shaped) dripper. I’d call this Kalita’s "bread and butter." Launched in 1959, it practically defined the home-brewing style in Japan.

The trapezoid shape was originally designed to fit the coffee carafes common in Japanese homes at the time. The three small holes at the bottom ensure even water distribution, allowing for a uniform extraction of the coffee bed. Meanwhile, Kalita’s signature "ribs" create channels between the filter paper and the dripper, preventing the paper from sticking and ensuring a smooth flow.


Including this dripper in the gashapon set is a nod to Kalita’s roots. It’s the "National Design" that brought coffee into the living room. The miniature even comes with a classic Kalita coffee scoop on a metal chain, making it a super cute accessory. Between the red and white versions, I think I’m partial to the white one!

Note: These three holes are usually 2-3mm in diameter—a precise measurement that dictates a moderate flow rate, perfect for the rich, full-bodied extraction of medium-to-dark roasts.

The "Nokia" of Coffee: Vintage Hand Grinders

Another heavy hitter in this collection is the replica of two iconic hand grinders: the Diamond Mill and the Classic Mill BR. They just ooze vintage vibes.

The Diamond Mill is a beast. The real version features a heavy cast-iron body and a signature wooden drawer. There’s something so romantic about the "functional aesthetics" of that drawer. It’s not just a part of the structure; it’s part of the ritual. Pulling it open to find neatly ground powder and that hit of fresh aroma is pure magic.

Actually, the wooden drawer isn't just for decoration; it’s part of the "original DNA" of 19th-century German "Solida" patent designs. Think of it as the "Nokia" of the coffee world—indestructible and classic. The grinding mechanism is completely separate from the catch bin, which was a huge leap forward from the early days when you had to brush grounds out from the bottom.

In the gashapon version, the handles actually turn and the drawers really open! The level of interactivity is incredible. While these vintage grinders might not match the precision of modern gear, they usually feature an adjustment nut that lets you switch from a coarse French Press grind to a fine pour-over. Plus, because they can be fully disassembled for cleaning, they often produce a more consistent grind than many later, "simplified" models.

The set also includes two versions of the Classic Mill, including the oak-body model. In the early days of specialty coffee, this was the gateway to "freshly ground" happiness for many. Though the fixed central shaft wasn't the stablest—leading to some unevenness and "fines"—modern versions have optimized the craftsmanship. (I even tucked a Kenya PB bean inside the tiny drawer of mine, haha!)

The Perfection is in the Details: Filter Paper & The Copper Kettle

One of the standalone capsules features the Kalita Trapezoid Filter Papers. It’s a three-piece set: a coffee scoop, a single filter paper (they even captured the texture of the crimped edges!), and a box of filters that looks exactly like the real packaging. This kind of attention to detail is why Japanese gashapon are so satisfying to collect. It’s actually my favorite piece in the whole set.

Finally, we have the Classic Kalita Copper Kettle—the brand’s aesthetic condensed into one object. In the world of Kalita, copper is the "holy grail."

Choosing copper wasn't just about the vintage look; it’s about physics. Copper’s thermal conductivity is 401W/m·K—about 16 times that of stainless steel. This means when you pour in hot water, the entire body heats up instantly, keeping the water temperature stable and preventing cold spots. For coffee extraction, stable temperature is key to a balanced flavor.


Because it conducts heat so well, it’s also sensitive to change. If you start with 92°C water, the temperature will naturally drop about 3-4°C during a 3-minute brew. This creates a "gradient extraction"—high heat at the start brings out the aroma and acidity, while the slightly lower temp at the end pulls out the sweetness and body. This "layered" flavor is exactly why veteran brewers are obsessed with copper.

It’s not a "perfect" all-rounder—it loses heat fast, has a specific flow rate, and requires high maintenance—but it remains the dream kettle for countless coffee lovers.

Ice Water Cold Brew Hack: Why This Method Tastes Sweeter, Smoother, and More Refreshing

 Cold brew, as the name suggests, is coffee made with cold water at low temperatures. The most common method is to soak ground coffee in room-temperature water, refrigerate it, and wait for the cold water to slowly pull out the flavors. After steeping, simply filter out the grounds and you’re done.

But here’s something fun: cold brew doesn’t have to be made with room-temperature water. You can actually make it with ice water—a mix of ice cubes and water brewed together with the coffee grounds. The big question is: Does it taste better?

Two Ways to Make Cold Brew

For this comparison, I made two batches of cold brew—one with room-temperature water and one with ice water. I kept all other variables as consistent as possible so I could really taste the difference.

1. Room-Temperature Cold Brew

I used my Colombian “Big Belly Button” beans, measured out 20g, and ground them to a coarse, sugar-like texture. Using a 20-mesh sieve, the grind had an 80% pass rate. (For reference: EK43s at 9.5, Comandante C40 at 24 clicks.)

Since this coffee has a fruity profile and doesn’t need a high concentration, I went with a 1:12 coffee-to-water ratio.

I added 20g coffee grounds and 240g filtered water to a clean, sealable container, stirred well, sealed it, and let it steep in the fridge for 12 hours. After that, I filtered out the grounds.

2. Ice-Water Cold Brew

Ice water extraction is just as easy. I again weighed out 20g of beans, but because ice water extracts more slowly at lower temperatures, I made the grind a bit finer—82% pass rate through the same 20-mesh sieve. (EK43s at 9, Comandante C40 at 22 clicks.)

Since the ice cubes I normally use are fairly large and melt slowly, I increased the proportion of liquid water and reduced the ice. My final ratio was:

1 : 8 : 4 (coffee : water : ice)
= 20g coffee, 160g water, 80g ice.

I combined everything, stirred, sealed, steeped for 12 hours, and filtered as usual.

Ice Water vs. Room Temperature—Which One Tastes Better?

Room-Temperature Cold Brew

  • Deeper color

  • Notes of blueberry, grape, and grapefruit

  • Medium fermentation aroma

  • Fuller body with a slightly bitter finish

Ice-Water Cold Brew

Because the ice didn’t fully melt during steeping, there were still small crystals left on the filter—which also meant the final yield was lower. Still, the result surprised me:

  • Bright flavors of grape, pineapple, orange, and cherry

  • Clean, sweet, juice-like body

  • Almost no bitterness

  • Refreshing and memorable, like a mixed fruit juice

Honestly, the ice-water version tasted shockingly good.

Why Does Ice-Water Cold Brew Taste So Different?

Temperature plays a huge role in coffee extraction. Higher temperatures speed up the release of soluble compounds; lower temperatures slow everything down. Compared to room-temperature water (around 18–27°C / 64–80°F), ice water sits between 0–10°C (32–50°F), making extraction noticeably slower. This means ice-water cold brew naturally contains fewer dissolved solids under the same steeping time.

But it’s not just about quantity—it’s about what gets extracted.

Coffee contains hundreds of compounds, all with different solubility characteristics. Some dissolve quickly, some slowly, and some only at certain temperatures.

In general, coffee flavors extract in this order:
acidity → sweetness → bitterness

Aromatic, fruity, and floral compounds tend to release first. Sweet caramel-like compounds follow. Bitter, heavier molecules usually come last.

When the steeping temperature drops close to 0°C, extraction becomes much slower—particularly for the larger, more bitter compounds. As a result, ice-water cold brew emphasizes bright, juicy, fruity notes while holding back harsher flavors. The result is a refreshing, sweet, almost juice-like cup.

No-Fail Pour-Over Coffee Guide for Beginners | Brew Café-Quality Coffee at Home

 Think pour-over coffee is only for “pros”? Not at all! You don’t need fancy equipment. With less than $30, you can get all the basic tools, follow a few simple steps, and brew coffee that tastes ten times better than instant. The secret lies in choosing the right beans, picking the right tools, and mastering three core techniques. Even beginners can easily get it right!

1. Essential Tools:

No need to splurge—five basics are enough.

The beauty of pour-over coffee is in its simplicity and purity. You don’t need high-end gadgets. With just these five essentials—costing around ¥100–300 ($15–40)—you’re good to go:

  • Grinder:

    • Manual: Affordable (under $20), easy to clean, and perfect for beginners on a budget.

    • Electric: Produces more consistent grounds with fewer fines, resulting in a cleaner taste. If you can, go electric from the start.

  • Gooseneck Kettle:
    A must for beginners! The thin spout gives you control over water flow, preventing you from disturbing the coffee bed. It greatly reduces the chance of over-extraction. Once you get more experienced, you can try a swan-neck kettle for finer control.

  • Dripper + Filter Paper:
    The most common drippers are flat-bottom (1–3 holes) and V60 cone-shaped.

    • Flat-bottom drippers drain more slowly (fewer holes = slower flow), making them beginner-friendly.

    • V60s have faster flow and require better pouring control.
      Always match your filter paper to your dripper’s shape and size, and rinse it with hot water before brewing to remove any papery taste.

  • Server (Sharing Pot):
    Ideal if you’re brewing for multiple people—it helps evenly distribute the coffee so every cup tastes the same. Brewing just for yourself? You can pour directly into your mug.

  • Optional Upgrades:

    • Digital scale: To control your coffee-to-water ratio.

    • Thermometer: To ensure ideal water temperature.
      If you like convenience, get a pour-over kettle with a built-in thermometer—it simplifies everything.

2. Choosing the Right Beans:

The single most important factor—responsible for 70% of the flavor.

The quality of your beans directly determines your coffee’s taste. Don’t blindly follow big “imported” brands—focus on two things: freshness and flavor compatibility.

1. Rule #1: Freshness Is Everything

  • The best flavor window is within two weeks after roasting—that’s when the aroma and body are most vibrant. Up to three weeks is acceptable; four weeks is the limit. After that, most of the fragrance fades.

  • Light roasts stay fresh a bit longer—maybe up to an extra week. Dark roasts oil out quickly, so finish them within 10 days and toss them after 3 weeks—they’ll just taste bitter.

  • Pro tip: Coffee loses most of its aromatic compounds within one minute of grinding! Avoid pre-ground coffee and so-called “imported, factory-roasted” beans that have been sitting for months. Always look for “recently roasted” beans and grind them fresh before brewing.

2. Beginner-Friendly Coffee Bean Recommendations

Each origin offers a different flavor profile. Pick according to your taste:

  • Love fruity, bright acidity?
    Try Ethiopian Yirgacheffe (vibrant orange and lemon notes, natural-processed ones even have winey aromas), Sidamo (citrus and berry sweetness with a chocolate finish), or Kenya AA (intense berry acidity—perfect for acid lovers).

  • Prefer smooth sweetness and lingering aftertaste?
    Go for Panama Geisha (similar to Yirgacheffe but with softer fruit acidity) or Panama Honey-Processed beans (rich sweetness with cocoa and honey notes, long aftertaste).

  • Hate acidity, love body and depth?
    Try Indonesian Lintong Mandheling (earthy and herbal with low acidity), Golden Mandheling (cleaner cup with caramel tones and bright fruit hints), or Aceh Gayo (balanced acidity with woody and fruity aroma, rich body like fruit juice).
    Brazilian coffees are also excellent for beginners—low acidity, nutty, mild, and very easy to drink.

  • Want a balanced, layered cup with lively acidity?
    Go for Guatemalan Huehuetenango—clean, crisp, and full of character.

3. Pour-Over Technique:

Master these 3 rules and you won’t fail.

The flavor of your pour-over depends mainly on three factors: grind size, water temperature, and brew time.
Remember these three rules, adjust through practice, and you’ll soon find your ideal taste:

  1. Grind Size:

    • Finer = More bitterness, less acidity.

    • Coarser = More acidity, less bitterness.
      (Tip: Start with medium-fine—like table salt.)

  2. Water Temperature:

    • Higher = More bitterness, less acidity.

    • Lower = More acidity, less bitterness.
      (Guide: 85–90°C / 185–194°F for light roast to preserve fruitiness; 90–95°C / 194–203°F for dark roast to enhance body.)

  3. Brew Time:

    • Longer = More bitterness, less acidity.

    • Shorter = More acidity, less bitterness.
      (Guide: For 200ml of coffee, total brew time should be around 1.5–2 minutes. Don’t exceed 2.5 minutes, or it’ll taste harsh.)

There’s no absolute standard for pour-over coffee. Adjust based on your own taste:

  • Like it brighter? Use coarser grind, lower temp, shorter brew.

  • Like it bolder? Use finer grind, higher temp, longer brew.

Try this starter recipe:
15g coffee (medium-fine grind) + 225ml water (1:15 ratio), 90°C water.
Bloom with a small amount of water for 30 seconds, then pour in 2–3 slow pulses. Total brew time: about 2 minutes.


Final Thoughts

The joy of pour-over coffee lies in the process itself—experimenting, adjusting, and discovering how every detail affects flavor. From bean selection to grind to water flow, every step brings you closer to your ideal cup. You don’t need to chase “professional” standards—if it tastes good to you, that’s the perfect coffee.
