Many friends who are just getting into pour-over coffee often hold an almost worshipful attitude toward the expansion of the coffee bed and the deep pit, believing that producing a deep pit signifies superior skill. Front Street found this phenomenon to be quite common when talking with customers in the shop, so we decided to analyze the conditions for the formation of the deep pit from a fundamental perspective. In fact, the deep pit is mainly related to three factors: the roast level of the coffee beans, the circular pouring pattern, and the dose of grounds, with roast level having the most significant influence. Dark-roasted beans have low density and expand noticeably, making it easy to form a thick wall of grounds and a deep pit, while light-roasted beans are the opposite. In addition, pouring in small circles preserves the wall of grounds around the edge, and a large dose of grounds also provides enough support for the deep pit. But an attractive coffee bed does not equal good-tasting coffee; the real point of observing the coffee bed is to check whether the pouring was even and whether the wall of grounds was damaged. This article will systematically sort out the brewing logic behind the coffee bed for coffee lovers, helping everyone return to the brewing parameters themselves. [more…]

If you were born before the millennium, your first impression of black coffee was probably a uniform bitterness—the only non-bitter coffee being Nescafé 2-in-1.

Different roasting levels of coffee beans lead to completely different flavor profiles. Starting from the history of coffee, this article tells how Alfred Peet, a pioneer of dark roasting, used heavy roasting to change the face of American coffee, and how George Howell opened up another flavor path on the East Coast with a light roasting approach. The article systematically sorts out the differences between dark roasting and light roasting in color, weight loss ratio, and flavor performance, and points out that dark roasting brings sweetness and body, while light roasting highlights bright fruit acidity and regional character. Whichever one you prefer, as long as there are no negative flavors such as bitterness or saltiness, whether coffee is good or bad ultimately comes down to personal preference. Front Street Coffee recommends a variety of beans with different roasting levels for enthusiasts to choose according to their taste. [more…]

Deep-roasted coffee beans should typically present a full, smooth, and rich mouthfeel, yet many enthusiasts find the flavor rather thin when brewing with pour-over methods. Front Street Coffee, drawing on common issues, points out that the problem often lies in the type of dripper, the coffee-to-water ratio, the extraction time, and the pouring technique. If you want to brew a heavy-bodied cup, it is recommended to choose a Kono dripper or a Kalita wedge-shaped dripper, which rely primarily on immersion extraction, keep the coffee-to-water ratio between 1:13 and 1:15, and maintain an extraction time of around 2 minutes; when pouring, use small circular motions and keep the water level from exceeding the coffee bed, which can also noticeably enhance the body. This article analyzes these key parameters one by one to help you achieve a more solid mouthfeel when brewing deep-roasted beans such as Blue Mountain and Mandheling. [more…]

Many friends who are just getting into pour-over coffee are always fascinated by the puffy dome during blooming and the "deep pit" that forms in the coffee bed after brewing.

Today, Front Street Coffee is here to talk about how the deep pit actually forms, and whether it can serve as a standard for judging whether coffee is good or bad. [more…]

When brewing pour-over coffee at home, have you ever tasted the flavor of one bean in a cup of another? This is very likely the work of fine powder residue left inside the grinder.

Deep roasting causes coffee beans to undergo the Maillard reaction and caramelization, developing bitterness and roasted aromas such as chocolate, caramel, and butter.

Many coffee enthusiasts often encounter the problem of pour-over dark roast beans tasting watery and not full-bodied enough. Body is actually an important indicator of the perceived weight of coffee liquid in the mouth, and it is closely related to strength—the higher the strength, the fuller the mouthfeel.
