Grind size is one of the core parameters determining the success or failure of coffee extraction, but the coarseness of coffee grounds is difficult to describe with intuitive numerical values, so sieve passing rate has become a more precise way to communicate. In this article, Front Street will systematically sort out the suitable grind levels for pour-over, cold brew (cold immersion and ice drip), French press, clever cup, moka pot, and espresso machine, and provide specific passing rate references for the No. 20 Chinese standard sieve. Whether you are a beginner who has just started or a veteran player looking to calibrate your grind, you can find corresponding parameter suggestions here. The article also specifically explains the differences between medium-light roast and medium-dark roast pour-over, adjustment methods for iced pour-over, and the reason why cold brew grind is not finer-is-better, helping you avoid common pitfalls and brew a full-flavored good cup of coffee.

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.

The coarseness of the grind in coffee directly affects the contact area between the coffee and water as well as the extraction time, and it will directly impact the taste of the coffee. But at the same time, the coffee grind size is also the most headache-inducing aspect for many people! In this article, Front Street will explain how to determine what the grind size should be for different coffee beans. First, [more…]

When faced with coffee beans processed in different ways, is it necessary to design a separate brewing recipe for each one? Front Street believes that rather than recording tedious parameters one by one and bearing the high cost of trial and error, it is better to categorize beans by processing method or roast level and use a single recipe with a broad coverage range. This article focuses on three processing methods—natural, washed, and anaerobic—explaining the differences in their flavor expression, as well as the targeted adjustments that can be made during brewing, including the thinking behind setting water temperature, coffee-to-water ratio, grind size, and extraction time. The article also specifically explains why anaerobically processed coffee drains faster, and how to ensure full extraction by grinding finer or switching to a slower-flow filter basket. All parameters are based on medium-light roasted beans, with adjustment suggestions for medium-dark roasted beans included. [more…]

Front Street Coffee believes that different roasting degrees will produce different flavor profiles, but many people have a misconception: is it enough to simply roast coffee beans to a certain roast color? Of course not—the flavor of coffee is not just about the roast degree, but also about the growing region. [more…]
