The coarseness of coffee grounds directly determines the contact area between water and coffee and the extraction time, which in turn affects the final taste. But grind size is also the most headache-inducing step for many enthusiasts. Starting from Front Street's practical experience, this article systematically explains how to determine the resting time based on the roast date, the actual impact of grind coarseness on flavor, and how to calibrate the grind size for different brewing methods using a No. 20 sieve. The article also compiles the suitable equipment for five particle sizes, from extra-fine to coarse, helping you roughly judge the grinding direction even without a professional sieve and find the grinding parameters that suit your own taste.

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.

In the coffee grinding process, the production of fines is almost an unavoidable phenomenon, regardless of whether one uses expensive professional-grade grinders or entry-level manual grinding equipment. However, the proportion of fines directly affects the stability of brewing and the final flavor presentation. Choosing a suitable grinder can, to a certain extent, help us reduce the troubles caused by fines. Front Street Coffee specifically conducted a comparative test on the differences in fines generation between manual coffee grinders and electric coffee grinders, analyzing the differences in grinding performance between the two from the perspective of burr structure, helping coffee enthusiasts more clearly understand the characteristics of different devices in grinding function, so as to make choices that better suit themselves.

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.

How coarse or fine you grind your coffee directly affects the contact area between water and coffee particles and the extraction time, and it is also a key variable that determines whether a cup of coffee tastes good or not. But grind size is precisely the part that many enthusiasts are least sure about. Starting from Front Street Coffee's practical experience, this article first explains the prerequisite effects of fresh roasting and bean resting on grinding results, then analyzes the different flavor directions of fine and coarse grounds, and afterward gives a specific method for calibrating the pass rate with a 0.85mm cupping sieve. It also lists reference ranges for light, medium, and dark roast beans, and finally includes a practical summary for judging coarseness by brewing device when you do not buy a sieve. [more…]

Coffee beans need to be freshly ground to fully appreciate their aroma, which shows how important grinding is for coffee beans. When grinding, many people have a misconception—namely, which setting they should choose. Generally, the largest number means a coarser grind, and the smallest number means a finer grind. However, every coffee machine, during assembly, transportation, and [more…]

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.

Grind size is the key variable that determines whether pour-over coffee can produce good flavor. Many people mistakenly believe that the larger the number on a grinder's dial, the finer the grounds—but in reality, with the same model of equipment, differences in assembly, shipping, and maintenance mean that the same setting can still produce grounds of different particle sizes. Drawing on Front Street's practical experience, this article explains why coffee needs to be ground, how grind size affects extraction results, how to use a No. 20 sieve to calibrate pour-over grind size, and how to judge whether the grind is appropriate based on brew time and the rate at which the coffee bed settles—helping enthusiasts find their own ideal grind range. [more…]

In an era where filter brewing devices are highly popular, Turkish coffee still insists on being consumed with the grounds, powder and all. This is not backwardness or laziness, but rather something shaped jointly by its sand-brewing extraction method, extremely fine grind size, and deep cultural tradition. From the perspective of Front Street, this article explains why Turkish coffee is not filtered: just how fine its grind really is, how it differs from espresso grounds, how the coffee powder quickly settles in a short time and gives the coffee a rich mouthfeel, and the fortune-telling custom that has arisen from keeping the grounds, helping you fully understand the logic behind this unique coffee culture. [more…]

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.
