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…]

Drip bag coffee has become the top choice for many people during business trips, office work, and travel thanks to its convenience—no need to grind beans or use professional equipment.

Many people believe that as long as they buy good-quality coffee beans, it will not taste bad no matter how they brew it, but this is not the case. Pouring water itself is an extremely critical extraction variable; it determines whether the coffee grounds can be extracted evenly and also directly affects the flavor performance in the final cup. Just as a chef constantly tosses food in the wok to heat it evenly when cooking, the pouring motion in pour-over brewing also requires different flow rates and strength at different stages to regulate the process. Starting from the fundamental purpose of pouring water, this article will explain why pour-over coffee requires attention to the pouring method, and specifically analyze the difference between a strong flow and a gentle flow, helping you understand how to achieve even extraction through flow control while avoiding the extraction of unpleasant substances.
