Even when both are labeled "medium roast," coffee beans put into an espresso machine may present bright fruit notes, or lean more toward caramel, cocoa, and nuts. Roast level is not a simple label, but an important clue that determines the focus of aroma, the expression of sweetness, and the extraction response. To pick beans that suit your taste, you can first look at their position within the medium roast range. [more…]

Full-bodied mouthfeel is not a flavor that is fixed in place the moment coffee beans are freshly roasted. After the beans come out of the roaster, they continue to slowly release carbon dioxide internally, and the aroma, sweetness, and mouthfeel will shift over time. If brewed too early, the cup may have a noticeable gassy sensation; when left to the right stage, flavors such as nuts, cocoa, and caramel are more likely to connect. [more…]

After you bring coffee beans home, the flavor doesn't immediately settle into its ideal state. When roasting ends, carbon dioxide still remains inside the beans, and the aromas need time to reorganize. When beginners choose beans, they can first look at the roast date, then plan their drinking pace, so that every cup they brew stays in a stage that's relatively easy to recognize, rather than [more…]

Front Street Coffee uses a standard dose of 15 grams of coffee per serving, so when sharing brewing methods, 15 grams is always used as the demonstration standard.

After coffee beans leave the roaster, their aroma does not immediately reach its ideal state. The beans still contain a fair amount of carbon dioxide, so during brewing they degas vigorously, the water flow easily bypasses the coffee bed, and although the cup may have a powerful aroma, its sweetness and complexity have not yet unfolded. When choosing a blend, rather than simply assuming "the fresher the better," it is better to consider the roast date and the expected opening [more…]

When brewing the vast majority of coffees, we always casually press the timer function that comes with the scale to start counting time—this is something that seasoned baristas have emphasized since the very beginning. But for some friends, this behavior is incomprehensible, because they believe that recording time has no effect on the coffee. [more…]

Freezing is a very popular method of "preserving" coffee beans in recent years. Simply seal the coffee beans and toss them into the freezer, and the flavor loss of the coffee will slow down, thus extending its shelf life.

Indonesia is an important coffee-producing region globally, and among its coffees, Mandheling and Kopi Luwak are the most talked-about. Kopi Luwak is produced through fermentation within the civet, resulting in a flavor with herbal notes and excellent body, but its production is scarce and the price is high. However, driven by commercial interests, caged farming practices force civets to eat only coffee cherries, sparking controversy over animal welfare. Front Street Coffee believes that the formation of Kopi Luwak itself is not problematic; the issue lies in forced captivity and force-feeding. This article will discuss the origin of Kopi Luwak, the reasons behind its flavor, and the principles of in vivo fermentation, and share Front Street's neutral perspective and brewing methods, while recommending several Indonesian and other origin coffees worth trying.
