In coffee brewing, the coarseness of the grind directly affects the extraction result, yet how to describe and judge grind size has long lacked a unified standard. Some people use fine granulated sugar as an analogy, some rely on the grinder's settings, and others, like Front Street Coffee, quantify it through sieving rate. Each of these methods has its pros and cons, but the ultimate goal is the same: to help us adjust the grind into the right range before brewing. This article will systematically sort through three common ways of expressing grind size—the setting reference method, the visual analogy method, and the sieve calibration method—analyze their respective limitations and applicable scenarios, and explain in detail the No. 20 standard sieve procedure used by Front Street Coffee, helping you find the most suitable grind parameters with fewer beans.

Many coffee enthusiasts feel confused after getting coffee beans: which grinder setting should they actually use? In reality, the burr designs and setting standards of grinders from different brands vary greatly, and the same number on different devices can produce dramatically different particle sizes. Therefore, when Front Street Coffee performs daily grind calibration, it uses the Chinese No. 20 standard sieve (0.85 mm aperture) to measure the passing rate as a unified reference. This article will start with the specific steps for sieve calibration, combine different roast levels and brewing methods to give grinding recommendations, and share how to judge whether the grind is appropriate based on brewing time and the settling state of the coffee bed, helping you build a grind assessment system that does not rely on grinder settings.

Grind size is the key variable that determines the success or failure of coffee extraction, and different brewing devices have significantly different requirements for particle diameter. This article systematically sorts out the corresponding grind settings from French press to espresso machine, introduces the industry-recognized cupping standard and the No. 20 sieve pass rate as calibration references, and provides specific scale references for the EK43s grinder. Whether you prefer immersion or pour-over, you can find suitable grind parameters here. The article also specifically reminds readers that coffee bean density and roast level will affect the actual particle coarseness at the same setting, so it is recommended to repeatedly confirm with the same beans. Several Front Street Coffee beans are also used as examples throughout to help readers understand the logic of grind adjustment more intuitively. [more…]

Grind size is the key variable that determines the direction of coffee flavor, but how coarse counts as coarse and how fine counts as fine has always lacked a unified standard. This article uses the industry-recognized cupping grind as a baseline, and with the help of the passing rate through a No. 20 standard sieve, quantifies the grind requirements for French press, pour-over, cold brew, ice drip, and even espresso machines one by one, and also includes reference settings for the EK43s grinder. The article also specifically reminds readers that differences in coffee bean density and roast level will cause the same setting to produce different particle sizes, and finally provides Front Street Coffee's espresso extraction plan as a debugging example to help enthusiasts turn grinding from an empirical judgment into a reproducible data-driven operation.

Grind size is one of the key variables determining coffee flavor. The finer the particles, the larger the contact area between hot water and coffee grounds, and the greater the resistance to extraction, which tends to prolong extraction time and increase the extraction yield; the coarser the particles, the opposite is true, and underextraction becomes likely. Different brewing devices have significantly different grind requirements, ranging from the flour-like extremely fine powder for a Turkish pot to the coarse particles for a French press, a very wide span. This article systematically sorts out the relationship between grind size, extraction time, and extraction yield, gives reference grind ranges for espresso and pour-over coffee, and, combined with Front Street Coffee's production experience, explains how to find a grind setting that suits you according to roast level and bean hardness, while also reminding you of the importance of daily maintenance of the grinder burrs.
