Many coffee enthusiasts are intimately familiar with latte art and equipment, yet when it comes to espresso extraction, they often overlook dosing, puck management, and tasting judgment. In fact, dose control is just as critical as grind size adjustment—fluctuations in dose mean that even the most beautiful latte art cannot mask an imbalance in the coffee itself. Starting from the TDS and extraction yield formulas, and drawing on a 2.3-gram dose difference measured on a Mazzer Robur grinder, this article uses charts and data to illustrate the specific effects of dose on concentration, extraction yield, and the balance between acidity and bitterness, and explores approaches to dosing for light-roast espresso. Front Street Coffee also emphasizes the importance of dose consistency in its daily output, and we hope this article offers practical reference for your extraction adjustments. [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 coarseness of coffee grounds directly determines the resistance and contact area when hot water passes through the coffee bed, which in turn affects the flavor direction of the final cup. A short extraction time requires finer particles to increase surface area; a longer time requires larger particles to avoid over-extraction. Grind size and extraction time need to form a proportional relationship to balance acidity, sweetness, and bitterness. Light and dark roasts also have different requirements for grind size: light roasts favor slightly finer grinds, while dark roasts favor slightly coarser ones. In addition, coarseness is also a key lever for controlling bitterness: too fine and all the astringent, bitter compounds are released; too coarse and the sweet aromatics remain trapped in the grounds. This article will systematically review how grind size affects extraction yield, flavor, and equipment compatibility, and offer practical directions for adjustment. [more…]

Grind size selection is a key factor determining coffee extraction quality. Because espresso uses high-temperature, high-pressure, short-time extraction, its requirements for particle fineness and uniformity are far higher than those of other brewing methods.

Cold brew coffee is often served in limited quantities at cafés, precisely because its production cycle usually exceeds eight hours. This type of coffee, which originated in Europe and gets its name from the Dutch invention of a distillation apparatus, is also called Dutch Coffee, distilled coffee, or water-drip coffee. It relies on condensed natural osmotic water pressure to let cold water drip through the coffee grounds one drop at a time, continuously extracting at a low temperature of about 5°C for several hours. The flavor of the finished product varies depending on the roast level, water volume, water temperature, drip rate, and grind coarseness. It has a rich, smooth, and refreshingly icy taste, making it the foundation for drinking straight in summer or for making iced coffee. Front Street Coffee's cold brew recipe also emphasizes the coordination between drip rate and grind. Below, we'll break down its extraction principles and time control. [more…]
