Many friends who originally used hand grinders have purchased an electric coffee grinder to grind coffee beans, with the aim of freeing their hands and no longer needing to go through the tedious grinding process. However, electric grinders are different from hand grinders, and there are many details to pay attention to when using them. If you are not careful, it is easy to shorten the life of the grinder and affect the grinding quality. [more…]

Many coffee enthusiasts, before brewing pour-over coffee, hear experienced baristas emphasize the step of "seasoning the grinder." But seasoning actually comes in two forms: one is the daily deep cleaning of the grinder, and the other is the "pre-grinding" done before each grind. The two serve different purposes and should not be confused. This article explains in detail why a small amount of beans from the same batch should be used to season the grinder before grinding coffee beans, how residual coffee powder and burr oils affect the flavor of the next cup, and why an air blower cannot replace bean seasoning. At the same time, Front Street Coffee will also offer recommendations on the amount of beans to use for seasoning, helping you present the true flavor of each bean in a purer way. [more…]

Coffee beans cannot be eaten directly after roasting; they must be ground into powder and extracted with equipment before they can be consumed. This article compiles for coffee enthusiasts the complete key points for home-brewing roasted coffee beans: when selecting beans, look at color uniformity and aroma; grinding is divided into coarse, medium, and fine levels, corresponding to different equipment; water temperature must be controlled below 96 degrees Celsius, and the best drinking temperature is 85 degrees; it also explains in detail the chewing test for choosing fresh beans, the resting period after roasting, and how to distinguish single-origin beans from blends. Finally, it recommends Front Street Coffee's high-cost-performance freshly roasted Arabica beans, with a cost as low as five or six yuan per cup, making it easy to drink good coffee at home. [more…]

Coffee grinding equipment is mainly divided into two categories: manual and electric. Different brands and price points not only affect appearance and grinding performance, but also determine differences in burr structure and particle size distribution. Regardless of which grinder you use, daily cleaning and regular maintenance of the burrs are key to extending the life of the equipment. The static electricity generated during grinding causes fine particles to stick to the metal burrs and the grounds bin. The more frequently it is used, the more residual grounds accumulate, and the oil released by dark-roasted beans worsens the buildup of oily residue. If not cleaned for a long time, old grounds not only produce a rancid oil smell, but also taint new grounds and clog the grinding path. This article will introduce grinder maintenance methods and precautions in detail across three levels: daily quick cleaning, cleaning without disassembly, and regular deep cleaning. [more…]

The first step in coffee brewing often begins with grinding. Different extraction methods have different requirements for coffee grounds: a French press needs coarse particles visible to the naked eye, while a Turkish pot requires a grind as fine as flour. At the same weight, the finer the grind, the greater the number of cuts and the larger the surface area, and the more opportunities water has to contact the coffee grounds, so flavor compounds are released faster. To move away from vague descriptions like "as coarse as granulated sugar," Front Street Coffee uses standard sieves to calibrate particle size: generally, pour-over coffee particles are between 600-850 microns; when tested with a 0.85 mm (No. 20) sieve, the pass rate is about 80% for light roasts and about 65-70% for medium-dark roasts. This article will also compare the pass rates of common methods such as cold drip, siphon, moka, American drip filter, cupping, and French press, and introduce the effects of conical burrs, flat burrs, and ghost teeth burrs on grinding results, as well as recommendations for choosing between hand grinders and electric grinders.

When grinding coffee beans, have you ever encountered powder splattering everywhere or clinging stubbornly to the grinder or portafilter? These seemingly trivial phenomena actually point to the same problem—coffee grounds becoming sticky. Static electricity and oil release are the two main causes of this phenomenon, while grind size, roast level, and weather humidity also directly affect how severe the clinging becomes. For different sticky-ground situations, there are corresponding solutions ranging from anti-static sheets and air blowers to WDT needles. Although the online trick of adding water to eliminate static works, it carries hidden risks. This article will break down the causes and solutions one by one, making the grinding process cleaner and smoother. [more…]
