Pu’er Coffee

 Among all espresso-based drinks, if someone asks which one contains the most milk, most of us would instantly answer: the latte. And lattes come in two main forms—iced (or cold) lattes and hot lattes. Even though the recipe is technically the same, the methods differ to bring out the best flavor in each version, which leads to many detailed variations in preparation. For iced lattes, the ratio between espresso and milk directly determines the overall strength of the drink. But when it comes to hot lattes, flavor isn’t only affected by ratios—milk temperature also plays a crucial role. What Temperature Should the Milk Be for a Hot Latte? The end point of steaming milk is mainly based on whether the temperature is high enough. Generally, in a specialty coffee shop, milk for a hot latte is steamed to around 55–65°C (or at least kept under 70°C). Many people may wonder: why this specific range? Next, we’ll walk through two sets of experiments to understand the reasons behind it. ...

 Finally! With the arrival of chilly air, we can truly feel the crispness of autumn — even if it’s only for a short while, it’s still something to celebrate. As temperatures drop, coffee behaves a little differently. And this change doesn’t just affect brewing — it also affects the coffee you’ve already made. Once a cup of coffee is brewed, it cools down much faster in cold weather than it would at room temperature. The greater the temperature difference, the faster the heat escapes. This rapid cooling shortens the coffee’s ideal drinking window , since we all know that hot coffee just doesn’t taste as good once it’s gone cold. But not everyone can finish a cup quickly. That’s why many coffee shops have started experimenting with ways to extend coffee’s “flavor life” — in other words, slowing down the cooling process. The Temptation to Make It Hotter Naturally, one simple idea is to start with a hotter drink. By brewing with slightly hotter water for an Americano or steaming mil...
