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.

In coffee brewing, grind size is often the key factor that determines the direction of flavor. Beans of different densities and roast levels will have different requirements for grind coarseness even when the same extraction method is used. This article will use common fine granulated sugar and coarse granulated sugar from daily life as references to systematically explain the brewing methods best suited to fine-sugar grinding and coarse-sugar grinding respectively, and, in combination with specific beans such as Front Street Coffee Gutingting Cooperative, Front Street Coffee Strawberry Candy, Front Street Coffee Sidra, Front Street Coffee Mandheling, Front Street Coffee Huilan, and Front Street Coffee Bird of Paradise, explain why light-roasted beans need a finer grind to improve extraction efficiency, while medium-dark roasted beans are suited to coarser particles to reduce the risk of over-extraction, helping you find a suitable grinding plan in different scenarios such as drip bags, pour-over, and cold brew.

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.

How coarse exactly should you grind for pour-over coffee? Many beginners are told the answer is "about the size of granulated sugar," but that description is not very helpful for those just starting out. Drawing on the daily experience of Front Street Coffee (FrontStreet Coffee), this article first explains the specific size range of granulated sugar particles, then explains why grind size directly affects extraction results, and afterward gives the ideal particle range of 0.6mm to 0.8mm along with the practical method of an 80% pass rate through a 0.85mm standard sieve. The article also combines two criteria for judgment—brewing time and the settling speed of the coffee bed—and uses Honduras Sherry beans as a sample to compare the cupping concentration differences between two grind settings, BG #8s and BG #3s, helping readers build a quantifiable way of thinking about grind adjustment.

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. [more…]

The flavor expression of pour-over coffee depends to a large extent on whether the grind size is appropriate. The grind size directly affects the speed at which water passes through the coffee bed and the amount of coffee compounds released; too coarse and the flavor is weak, too fine and the flavor is strong or even bitter. This article begins with the mechanism by which grinding affects flavor, introduces a method using granulated sugar particles as an intuitive reference, and further provides the operational details for precisely checking grind size with the Chinese standard No. 20 0.85mm sieve, along with Front Street's specific setting recommendations for medium-light and medium-dark roasted beans. In addition, it also outlines extraction time as a reference standard for judgment, as well as key factors affecting the taste of pour-over coffee such as coffee bean selection, making it suitable reading for coffee enthusiasts who want to systematically master grinding techniques.

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…]

Grind size is the key variable that determines the direction of coffee flavor, but grinders on the market have wildly varying scales, and the same number may correspond to dramatically different coarseness on different devices. How fine is actually fine? How should you judge something the size of granulated sugar? This article starts from the impact of grind size on extraction, systematically introduces how to quantify the coarseness of coffee grounds with the help of the Chinese standard No. 20 0.85 mm aperture sieve, and for common brewing methods such as pour-over, French press, cold brew, espresso machine, and moka pot, provides reference ranges for grind passing rates under different roast levels and comparison methods, helping you find the grind parameters suitable for your own equipment.

Grind size directly determines the extraction direction of a cup of coffee: too fine a grind easily leads to over-extraction and bitterness, while too coarse a grind may result in under-extraction and a weak, bland flavor. Many grinders on the market mark their settings from 1 to 10, but the corresponding coarseness varies across different models. A smaller number usually means a finer grind, but in practice, you need to judge based on your brewing method. Drawing on the hands-on experience of Front Street Coffee, this article sorts out the grinding ranges for common brewing methods such as espresso, pour-over, siphon, and French press, explains whether medium-light roast and medium-dark roast coffee beans are better suited to a medium-fine or medium-coarse grind for pour-over, and provides specific steps for using a 0.85mm No. 20 sieve to check the passing rate, helping coffee enthusiasts find the right grinding parameters.

In coffee brewing, the grind size has a crucial impact on flavor. If the coffee grounds are too coarse, extraction will be insufficient and the taste will be weak; if too fine, it easily brings out bitterness. This article will systematically sort out the grind size standards corresponding to three brewing methods: pour-over, espresso, and moka pot, and provide extraction ratio and time references. The pour-over section will distinguish the grind pass rate, water temperature recommendations, and sieving verification methods for medium-light and medium-dark roasted beans; the espresso section explains the extremely fine grind and adjustment logic under 9 bar high pressure; the moka pot section introduces the suitable grind range and bean selection approach under 1.5-3 bar pressure, while retaining Front Street Coffee's practical data and product recommendations, making it convenient for coffee enthusiasts to adjust by comparison.
