Pu’er Coffee

 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 pr...

 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 m...

 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 ...

 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 ...

 After talking with plenty of coffee enthusiasts, I’ve noticed that this seems to be one of the biggest curiosities people have about grinders: If it can grind coffee beans, can’t it grind other things too? And that’s usually when a few “mad experimenters” begin a series of questionable trials—only to fall into complete silence afterward… Let me put it plainly: please don’t use your coffee grinder to grind anything other than coffee beans , especially if you actually care about it. Seriously. 😄 To be honest, no matter which stage of my coffee journey I’ve been in, I’ve never even considered this question. To me, a grinder is a tool with a very clear, single purpose. Trying to repurpose it for other kinds of grinding just doesn’t make much sense. Sure, in theory , anything softer than the burrs might get crushed—but from a practical and safety standpoint, it’s a very bad idea. First, let’s be clear about one thing: the heart of any grinder is the burr set. Whether it’s flat burrs...

 While ordering a straight espresso isn’t all that common in many coffee shops in China, the scene looks very different abroad—especially in Europe. There, starting the morning with a single espresso is almost second nature. If you pay close attention, you’ll notice that an espresso is almost always served with a small glass of water and a spoon. This pairing has become an unwritten standard in cafés around the world. Today, let’s talk about why such a small cup of coffee comes with a glass of water and a spoon—and what roles they actually play. The Role of the Glass of Water Let’s start with the water, which is relatively easy to understand. No matter what kind of coffee you order, a glass of water is often considered an essential part of good café service. Beyond simply quenching your thirst, its most important function is to cleanse your palate. Espresso is intensely aromatic and concentrated. Taking a sip of water before your first taste helps wash away lingering flavors fro...

 Be honest—do you do this too? Every time you buy coffee beans, the first thing you look for is the roast date. As long as it’s fresh, you feel safe. If the “best before” date is still a month away, into the cart it goes. If there’s only two weeks left, doubt immediately kicks in. Stop. Put that bag down. Here’s a little secret: the date on the bag is just the coffee’s birth certificate . What truly determines whether a coffee will surprise you—or disappoint you—are several far more important details that most people overlook. Learn to read them, and your coffee-buying skills will instantly level up. Your wallet and your taste buds will thank you. 1. Origin & Processing Method Let me ask you something: Why does someone from Northeast China sound completely different from someone speaking Cantonese? Coffee works the same way. Its “accent”—in other words, its flavor—has already been shaped by where it comes from. That small line of text on the bag, like “Ethiopia ...

 If you often visit coffee shops for pour-over coffee and ask the barista whether a certain bean tastes better hot or iced, chances are they’ll recommend the hot version. Just yesterday, a friend buying beans complained about this and asked me, “Why do pour-overs have to be hot?” To be fair, the reason baristas recommend hot pour-overs isn’t because hot brews necessarily taste better than iced ones. As I’ve always emphasized, compared to iced pour-overs, hot pour-overs allow you to taste a more complete expression of a coffee’s flavors. Why does a hot pour-over offer more complete flavor? Most coffee shops — including mine — make iced pour-over using a flash-chill method. This means lowering the temperature by adding ice directly into the coffee so you can quickly get a cold cup of pour-over. But since the ice melts while cooling the coffee, the overall concentration inevitably becomes diluted. If we don’t want to end up with a watery cup, we need to increase the coffee concent...
