Pu’er Coffee

 The first time I tried a Dirty coffee served in an ultra-low-temperature ice cup was back in 2023, at UNCLE SHU Coffee in Binjiang, Hangzhou. It was my first real encounter with that striking “hot-meets-cold” contrast, and the experience left a strong impression. Dirty coffee is something most coffee lovers in China are already familiar with. It’s fairly common in cafés across Asia, yet you’ll rarely find it in Europe or the U.S. At its core, a Dirty is simple: ice-cold milk topped with hot espresso. This collision of temperatures creates a dramatic, almost theatrical drinking experience that many people love. In recent years, however, a new trend has taken things to the extreme—using ice cups chilled to −86°C to make Dirty coffee. Compared with a traditional Dirty, which usually uses milk and a cup chilled to around 4°C, a −86°C ice cup paired with espresso at roughly 65–70°C creates a temperature difference of more than 150°C. This extreme contrast delivers a sharper, more int...

 Coffee and protein powder—perfectly normal on their own. But when you mix them together, things start to feel… a little strange. Still, for people who want both energy and nutrition , “protein coffee” has become the ultimate hybrid drink. By blending coffee with protein powder or ready-to-drink protein shakes, this viral combo promises three major benefits: energy + protein + weight control . With all these buffs stacked together, it quickly took over social media. But is this trendy drink really as magical as people claim? Who should drink it—and how do you drink it correctly ? Let’s break down protein coffee from a scientific perspective so you can avoid mistakes and maximize benefits. 1. First Things First: Why Do People Drink Protein Coffee in the Morning? Protein coffee became popular because the “energy boost of coffee” perfectly matches the “nutritional benefits of protein,” especially for busy individuals. 1. Protein at Breakfast: Controls Appetite + Protects Muscle ...

 Do you still remember CLR CFF, the colorless, crystal-clear coffee that went viral nearly a decade ago? I was lucky enough to actually try that “internet-famous” product back then. For so long, we all believed coffee could be reddish-brown, brown, or even red—but it never crossed our minds that coffee could exist as something completely transparent. When CLR CFF was first released, it immediately caught the attention of coffee lovers. It became the world’s first colorless coffee drink, and its production process was always described in a vague, mysterious way—“made with methods never used before.” It sounded almost mythical, and no one ever seemed to crack the secret behind it. Today, the brand’s social media accounts have gone silent, its official website is no longer maintained, and similar products have essentially vanished. So how did they manage to make coffee completely clear? Let’s talk about this “mysterious” technology. Simply put, the core idea is to keep the flavor and ...

 A new “edible coffee cup” has quietly gone viral across social platforms, becoming a must-try item for young consumers. On Xiaohongshu alone, over 38,000 users have posted about it, and total views have reached nearly 10 million—and the number keeps climbing. So, what exactly is an edible coffee cup? It’s an innovative concept emerging from the specialty-coffee scene: a cookie-like cup made from oat flour and other grains, baked into shape and coated with a layer of chocolate on the inside to prevent leakage. The cup can hold coffee for more than 30 minutes, making it fully functional while also fun and delicious. With both novelty and practicality, it perfectly hits consumers’ curiosity and has sparked a trend across multiple cities in China. ACOC Specialty Coffee in Chongqing is one of the first to ride this wave, and its signature drink, the Black Sesame Vienna , has become a viral sensation. Served in a crispy oat-cookie cup and topped with fluffy black-sesame cream, the drin...

 Every morning in office buildings you’ll see coworkers clutching a cup of coffee — like they can’t function without it. But things have flipped: some Silicon Valley folks are actually using coffee to help them nap . As life speeds up, more young people have joined the “I’m exhausted, coffee is my steel” club. Over time, many develop a kind of caffeine immunity : they can drink coffee in the afternoon or evening and still fall asleep at night. Now cue concerned relatives and a chorus of wellness accounts: “Just take a nap! Napping is better than coffee!” True — a short nap is a proven way to shake off sleepiness. But what if you combine coffee and a nap? Turns out, that combo can work even better. How Caffeine Keeps You Awake Caffeine wakes you up by blocking adenosine , a chemical in the body that promotes sleep. Adenosine binds to receptors in the brain and reduces neuron activity, which makes you feel drowsy. Because caffeine’s molecule looks similar to adenosine, it can bin...
