"How big of a difference can there be between coffee with a 30-second bloom and a 60-second bloom?" This was a question a friend asked Front Street Coffee yesterday. I have to say, this question is actually quite interesting! As we all know, blooming is a routine step in pour-over coffee. Specifically, before the official pour, we pre-pour [more…]

Recently, a friend came across a post online: "If the blooming time is too long, it's easy to brew coffee that is under-extracted." Obviously, this statement goes against our long-standing understanding of blooming. Because as everyone knows, the purpose of blooming is to release the carbon dioxide in the coffee grounds, allowing us to more easily extract the coffee. [more…]

As the saying goes: "Bloom well, and brewing is trouble-free." For pour-over coffee, blooming is a very important preparatory step. So-called blooming is the step where, before we formally extract the flavor compounds from the coffee, we use a small amount of hot water to pre-wet the coffee grounds and wait for a certain period of time.

So how can you brew a perfect-tasting pot of pour-over coffee? In the rest of this article, Front Street [more…]

What is the English for pour-over coffee? If translated literally, it could be rendered as "Hand coffee," but that term is definitely incorrect. Next, expressions like "Hand punch" are also common mistranslations. The correct term should be "Pour over coffee." Now, pour-over [more…]

Freshly roasted single-origin coffee beans are filled with a large amount of carbon dioxide inside. If they are ground and brewed immediately, the intense degassing reaction will form many bubbles in the coffee bed, preventing the hot water from fully contacting the coffee grounds. Giving the beans a period of steady resting time allows the gas to escape slowly, so that the internal aromatic compounds can be released during extraction. [more…]

Pour-over coffee is a process where flavor extraction and filtration happen simultaneously, with extraction occurring centered around the spot where water is poured, and the key lies in how to control and balance it. At Front Street, when adjusting pour-over coffee parameters, we usually consider the grind size of the coffee beans and the brewing water temperature first, but in fact the coffee-to-water ratio is also very important. During brewing, the water [more…]
