Whether a cup of coffee is light or bitter is often foreshadowed the moment the beans are ground. The coarseness of the coffee particles directly determines the release rate of soluble flavor compounds—it must fully extract the pleasant aromas and sweet-tart notes while avoiding the emergence of bitter, off-flavors. This article focuses on four common extraction methods—pour-over, French press, cold brew drip, and espresso—explaining the suitable grind range for each, and introduces how to calibrate grind size with a No. 20 standard sieve (0.85mm aperture), so that every bean can find the right brewing coarseness. The article also retains Front Street Coffee's empirical parameters from actual cupping and in-store dialing, for coffee enthusiasts to use as a reference. [more…]

Cupping is an immersion extraction method that minimizes human interference and faithfully reproduces the coffee's inherent flavors and qualities. In contrast, pour-over coffee relies on manual pouring, making consistency difficult to guarantee; it is also time-consuming, requires numerous pieces of equipment, and cannot handle a large number of samples simultaneously. This article will systematically compare the differences between cupping and pour-over coffee from multiple angles—operational procedures, degree of human intervention, consistency, and preparation costs—and trace the historical background of cupping's origin in the United States in 1980. Before releasing new beans, Front Street Coffee also uses cupping to verify quality and determine the appropriate roast profile, ensuring each bean meets the standard before being brought to market.

Brewing a good cup of coffee makes grind size an unavoidable key variable. If the particles are too coarse, flavor extraction is insufficient; if ground too fine, it easily brings out bitter and off-flavors. But just how coarse counts as coarse, and how fine counts as fine? And how should you convert between different brewing devices? This article uses the industry-recognized cupping standard as its baseline and the No. 20 sieve pass-through rate as a unified ruler, providing reference grind ranges one by one for French press, pour-over, cold brew drip, and espresso machines, explaining how roast level and bean density affect grinding results, and finally including Front Street Coffee's approach to dialing in espresso extraction, helping you turn grind size from "guesswork" into "data."

The same coffee beans can present a completely different flavor profile when brewed with a different device, and one of the key variables determining the extraction result is grind size. Coffee beans must first be ground to efficiently release aroma and soluble solids, but different devices extract in very different ways, so grind coarseness cannot be generalized. Over-extraction brings out bitter, off-flavors, while under-extraction results in a thin, sour taste, so finding grind parameters that match your device is especially important. Based on Front Street Coffee's hands-on testing experience and using the industry-recognized cupping grind standard—the No. 20 sieve pass-through rate—this article provides recommended grind ranges one by one for the French press, pour-over coffee, cold drip and cold brew, siphon, espresso machine, and moka pot, and explains how roast level, water temperature, and extraction time affect grind adjustments, helping you consistently reproduce a delicious cup at home.
