The coarseness of coffee grinding directly affects the efficiency of extraction and the final flavor performance, making it one of the key variables that determine whether a cup of coffee is good or bad. From extremely coarse cold brew grinding to Turkish grinding as fine as flour, seven different particle sizes each correspond to the most suitable brewing equipment and methods. This article systematically sorts out the appearance characteristics of each grind size, the applicable scenarios, and why grinding fresh at home preserves flavor better than buying pre-ground coffee powder. It will also explain the taste problems that may arise from improper grind size selection, helping you quickly find the appropriate grinding parameters based on the equipment you have on hand, so that every cup of coffee can present the ideal layering of flavor.

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…]

It also introduces emergency grinding methods such as mortar and pestle, hammer, rolling pin, and blender, as well as Front Street Coffee's product recommendations. Whether you are a beginner or an enthusiast, you can find a grinding solution that suits you, making every cup of coffee rich and delicious. [more…]

Grinding is crucial to coffee extraction—one could say that the coarseness of the coffee grind directly affects the flavor of a cup of coffee. And for different extraction methods, the coffee grind size also needs to be adjusted. The coarseness of the coffee grind directly affects the length of extraction time and the level of extraction yield. Coffee grind [more…]

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.

Grind size is the key variable that determines the success or failure of a cup of coffee's flavor. Facing the 1 to 10 settings on a grinder, which number actually represents the finest? And how should different brewing methods match grind coarseness? Starting from Front Street Coffee's hands-on experience, this article systematically sorts out the mechanisms by which grind size affects extraction efficiency, compares the grind standards for common brewing methods such as espresso, pour-over, siphon, and French press, and focuses on explaining grind recommendations for medium-light and medium-dark single-origin beans in pour-over scenarios, water temperature pairing, and how to use a 0.85mm No. 20 sieve to precisely calibrate grind size, helping coffee enthusiasts establish clear adjustment logic.

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.
