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.

How should you determine the grind size for pour-over coffee? This is the first challenge many coffee enthusiasts encounter when getting started. This article systematically introduces three methods for judging grind size—visual analogy, grinder setting reference, and sieve calibration—analyzing the pros, cons, and applicable scope of each, and further introduces the advanced concept of "particle size distribution" to help understand how grind uniformity affects extraction. At the same time, Front Street Coffee, drawing on its own brewing framework, shares how to combine visual observation, data, and brewing tests to find the pour-over grind size that suits you in a more practical way.

Among the many variables in pour-over coffee, grind size is often the hardest to describe precisely in words. Every enthusiast uses a different grinder, so when baristas communicate with customers, they usually have to rely on everyday seasonings as analogies. Although this approach has its limitations, it is an effective way to quickly establish a brewing framework. This article will systematically sort out the applicable scenarios for four grind reference points—fine salt, fine granulated sugar, coarse granulated sugar, and sea salt texture—and, using a natural-process red cherry coffee as an example with the MAVO Wizard 2.0 manual grinder, demonstrate how to gradually "blind-test" your ideal setting when faced with an unfamiliar grinder by observing the bloom pattern, drawdown time, and coffee grounds condition, helping you find your own cup of good coffee.

There is no unified quantitative standard for coffee grinding, so enthusiasts often use everyday ingredients as analogies to quickly convey the concept of particle size. Common reference points like fine granulated sugar, coarse granulated sugar, sea salt, fine salt, and flour each correspond to different brewing methods and roast levels. This article goes through the particle size characteristics and suitable scenarios for each of these analogous grinds one by one: fine granulated sugar is mostly used for light-roast pour-over, coarse granulated sugar suits medium-dark roast beans, sea salt-like texture is suitable for immersion extraction methods like the French press, fine salt-like texture serves the fast-paced extraction of the moka pot, and flour-like texture is divided into two categories: espresso and Turkish coffee. The grind size described by each analogy is a range, not a single fixed value, and understanding this point helps with more flexible grind adjustment. [more…]

Bought Starbucks coffee beans but feel puzzled by the grinder settings? Grind size directly determines the success or failure of a cup of coffee. This article uses common everyday items like fine granulated sugar, coarse granulated sugar, sea salt, fine salt, and flour as analogies to help you quickly find the right grind size for pour-over, French press, moka pot, and espresso machine. Beans of different roast levels have different densities, so the same extraction method requires different grinds. Front Street Coffee will guide you through understanding the particle size range corresponding to each grind state, and why light-roasted beans need a finer grind while dark-roasted beans need a coarser grind, so you no longer have to agonize over grind size. [more…]

Slurping is a common tasting action in coffee cupping. By rapidly drawing the coffee liquid into the mouth, it becomes atomized, allowing a richer array of aromas and flavors to be captured through retronasal olfaction. This article will analyze slurping from several angles: its underlying principle, specific operating methods, practical effectiveness, and whether it is necessary to perform it in a café. At the same time, the article will use an analogy to everyday soup drinking to aid understanding, and explore the potential impact on mouthfeel and the social awkwardness that slurping may cause in a quiet café. Whether you are a beginner just getting into coffee or an enthusiast looking to refine your tasting skills, you will find practical reference here. [more…]

When brewing pour-over coffee, the vast majority of brewers choose to pour in a circular motion rather than a single-point pour or stirring. Behind this lies a key consideration regarding extraction uniformity and the risk of over-extraction. Starting from actual tests by Front Street Coffee, this article uses an analogy of instant powder particles to explain why the coffee bed needs agitation, analyzes why a single-point pour leads to uneven extraction, and further explains how circular pouring, compared with other agitation methods, can better reduce turbulence and avoid bitterness, thereby becoming the most fault-tolerant and practical pouring technique. [more…]
