Many espresso grinders come with a dosing function: set the target weight in grams and it dispenses the grounds automatically, which seems to save you the trouble of weighing each dose. Yet plenty of coffee shops, Front Street Coffee included, still double-check the dose on a separate scale. The reason is that a grinder's dosing isn't always accurate—retained grounds in the chute, static and other factors mean the actual output often differs from the set value. So how much difference does a few tenths of a gram really make to an espresso? Front Street pulled two shots each at 19.5g, 20g and 20.5g and compared them. The results showed that both extraction time and extraction yield changed with the dose, and that mouthfeel and flavor differed noticeably too. Using measured data, this article explains how small dose adjustments affect espresso extraction, and why cafés need to pay attention to these details in the cup they serve. [more…]

The extraction time of pour-over coffee is not an isolated number; it has a positive correlation with the extraction yield. When the extraction yield falls within the generally accepted ideal range of 18% to 22%, the coffee flavor usually performs better, and when this range is projected onto the time axis, it forms an optimal time range tied to a specific brewing recipe. Front Street Coffee uses the example of a light roast with 15 grams of grounds, a 1:15 ratio, 91°C, an 80% pass rate through a No. 20 sieve, and a three-stage pour, giving a reference range of 1 minute 50 seconds to 2 minutes 10 seconds. However, many enthusiasts find that even with identical parameters, the actual drip time may still be longer. This is often related to factors such as the grinder's particle size distribution and pouring habits. This article will break down these variables one by one and introduce the 4-6 brewing method, which uses time itself as a control lever, to help readers master the rhythm of pour-over more calmly.

The same shop, the same beans, yet the americano can often come out tasting like two completely different cups—Front Street Coffee's store received exactly this kind of feedback from customers this week. The article starts with the minimalist essence of the americano: "espresso diluted with water." Since the recipe is fixed and water has no flavor of its own, any variation can only come from the espresso itself. It then breaks down, one by one, four variables that are often overlooked: the resting rhythm and ongoing degassing of the coffee beans, the interference of rainy, high-humidity weather with grinding and pressurization, particle size drift caused by hopper pressure, and the heat effects of a grinder running nonstop. It also includes the actual brewing parameters and bean-resting experience for Front Street Coffee's Warm Sun beans, helping you understand the story behind the flavor ups and downs of a single cup of iced americano.

Regarding whether an electronic scale is needed when making coffee, two completely different voices have always existed within the coffee community. One side insists that a scale is a key tool for ensuring extraction quality, while the other feels that a few grams more or less makes no difference, and the taste of the espresso will not change noticeably. To verify this controversy, Front Street Coffee designed a set of comparative experiments, testing respectively from the two dimensions of different dose and different liquid weight, using actual tasting to reveal how a change of a few tenths of a gram in dose affects the flavor of espresso, and whether an electronic scale is actually necessary in daily coffee production. [more…]

Even when extracted with the same espresso machine, dark-roasted beans and medium-dark-roasted beans take coffee in two different directions. The former often carries notes of roast, cocoa, and nuts, with a thick, full body in the cup, making it suitable for producing an espresso with a clearly defined presence; the latter retains more of the beans' sweet aroma and acidity, so the espresso is more varied when drunk on its own, and even after milk is added, a clear flavor can still remain.
