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…]

In the daily preparation of pour-over single-origin coffee, electric grinders are being chosen by more and more enthusiasts.

For example, the seemingly simple question of when to add beans involves the key principle of burr protection. In addition, cleaning an electric grinder has two levels: daily and periodic, and only good maintenance can effectively extend its service life. This article addresses these practical points one by one to help you grind single-origin coffee beans with greater ease. [more…]

If you love brewing pour-over coffee at home, have you ever noticed that your brewed coffee tastes like it's mixed with other beans? This is very likely the work of fine powder residue left inside your grinder. Over time, static electricity causes fine powder to cling to the burrs, and the oils from dark-roasted beans build up as well. Before long, this not only affects flavor but can also clog the chute and shorten the machine's lifespan. So how exactly should you maintain your grinder? How often should you clean it? What's the difference between cleaning a hand grinder and an electric grinder? Can the burrs be washed with water? Front Street Coffee has put together a complete process, from simple daily cleaning to deep disassembly, to help you resolve all your grinder maintenance questions. [more…]

Grind size is one of the key variables determining coffee flavor. The finer the particles, the larger the contact area between hot water and coffee grounds, and the greater the resistance to extraction, which tends to prolong extraction time and increase the extraction yield; the coarser the particles, the opposite is true, and underextraction becomes likely. Different brewing devices have significantly different grind requirements, ranging from the flour-like extremely fine powder for a Turkish pot to the coarse particles for a French press, a very wide span. This article systematically sorts out the relationship between grind size, extraction time, and extraction yield, gives reference grind ranges for espresso and pour-over coffee, and, combined with Front Street Coffee's production experience, explains how to find a grind setting that suits you according to roast level and bean hardness, while also reminding you of the importance of daily maintenance of the grinder burrs.
