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…]

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.

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.

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.

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. [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.

Grind size has a decisive influence on the final flavor of a cup of coffee: if the grounds are too fine, over-extraction is likely; if too coarse, under-extraction may occur. Faced with the 1-to-10 settings on a grinder, many coffee enthusiasts don't know how the numbers correspond to coarseness, nor are they clear about what grind level to choose for different brewing methods. Drawing on the practical experience of Front Street Coffee, this article systematically sorts out the standards for coffee grind size, the appropriate grind levels for common brewing methods, and the reference values for the EK43 grinder. It also explains in detail how to use a 0.85mm No. 20 sieve for sieve verification, helping you accurately judge and adjust grind size at home, so that every cup of coffee can consistently present its ideal flavor. [more…]

There are many factors that affect the taste of coffee. During the brewing process, the factors that influence coffee include the coffee-to-water ratio, grind size, water temperature, etc. Among them, grind size can be said to be very important. There is a saying in the industry: "You can buy a cheaper coffee machine, but the grinder must be the best." It has to be said that grinding really has an [more…]

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.

The choice of coffee grind size directly determines the success or failure of a cup of coffee. From the ultra-fine powder for Turkish coffee to the coarse particles needed for a French press, every brewing device has its corresponding grind standard. The finer the grind, the higher the extraction rate and the slower the water flow; the coarser the grind, the opposite. There are assembly tolerances between different grinders, so even the same setting may not produce coffee grounds of the same coarseness. This article systematically sorts out eight grind levels from finest to coarsest, matching them one by one with devices such as espresso machines, AeroPress, siphon brewers, pour-over, moka pots, cold brew, and French presses, and combines Front Street Coffee's brewing examples to help coffee lovers find a grind plan that suits them.

Grind size is one of the core variables that determines the direction of coffee flavor, yet many who are just getting into pour-over brewing still feel unclear about its principles and practical application. Using five grind levels as a thread, Front Street Coffee systematically sorts out the logic linking everything from extra-fine powder to coarse powder with different brewing devices, and draws on hands-on cases such as espresso, drip bags, pour-over, siphon, and French press to explain how grind size affects extraction resistance, flow rate, and the final flavor. The article also weaves in the brewing parameters and flavor descriptions of several coffees currently sold by Front Street Coffee, emphasizing that the numerical grind setting itself has limited reference value—what truly matters is the ability to flexibly adjust coarseness and fineness according to different bean characteristics and brewing devices.

Grind size is the key variable that determines the success or failure of a cup of coffee extraction. If the grounds are too fine, they tend to over-extract and become bitter; if the grounds are too coarse, the extraction is insufficient and the flavor is weak. Starting from the practical experience of Front Street Coffee, this article systematically explains the mechanism by which grind setting affects extraction efficiency, sorts out the grind ranges corresponding to different brewing methods such as espresso, pour-over, and French press, and focuses on explaining the setting of the EK43s grinder in the pour-over scenario—medium-light roast beans are recommended at 10, and medium-dark roast beans at 10.5. It also introduces the specific operation of using a 0.85mm No. 20 sieve for sifting verification, helping coffee enthusiasts quickly judge and correct the grind size, so that every cup of coffee can consistently present the ideal flavor.

Beginners in pour-over coffee often come to FrontStreet Coffee and ask how to determine the grind size for each coffee bean, what effect grind size has on coffee extraction, how to tell the coarseness of coffee grounds at home, and so on. In this article, Front Street will talk about [more…]

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…]

Which grind size from 1 to 10 is the finest for coffee beans? In most cases, the smaller the number, the finer the grounds. The grind size of coffee beans plays an important role in extracting a cup of coffee. For example, if the coffee grounds are too fine and used for pour-over coffee, it will result in over-extraction, while if they are too coarse, it will result in under-extraction. Secondly, factors such as the beans from each producing region [more…]

Grind size is one of the core variables that determines the direction of coffee flavor. If the grounds are too coarse, flavor compounds are under-extracted and the coffee tastes thin as water; if the grounds are too fine, bitterness and off-flavors are over-released, throwing the cup out of balance. It is often said in coffee circles that "the grinder is more worth investing in than the coffee machine," which shows just how critical grinding is. This article systematically covers the medium-fine and medium-coarse grind standards for pour-over coffee, the practical method of sifting grounds with a 0.85mm sieve, the ultra-fine grind required for espresso under 9 bar of pressure, and the grind range for the moka pot that falls between the two. It also draws on Front Street Coffee's brewing experience to offer water temperature recommendations for different roast levels and espresso blend bean recommendations. [more…]

The grind size for pour-over coffee has always been a problem that puzzles many enthusiasts—the same description of "coarse sugar size" can be understood very differently by different people, and communication deviations directly lead to flavor differences. To solve this problem, Front Street Coffee adopted a "sieve calibration method," using a No. 20 sieve to quantify the grind level. This article will introduce the operating steps of this method in detail: how to choose a sieve, how to measure the pass-through rate, why it is recommended to control it at 80%, and when the grinder quality is poor, how to use brewing time and coffee bed state to assist in judging whether the grind is appropriate. No matter what grinder you use, this method can help you find a relatively stable grind reference. [more…]
