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…]

Many coffee enthusiasts are familiar with using a moka pot and the brewing techniques involved, but how to properly clean and maintain it afterward is often overlooked. Although Front Street Coffee has shared a great deal of content related to moka pots, it has never systematically covered the topic of cleaning, and as a result, the back office keeps receiving requests for help with pots that have "turned black."

Over time, a moka pot can develop dark spots or patches on its body, and this is usually caused by improper cleaning methods. Many people focus only on how to brew coffee with a moka pot, but overlook that cleaning and maintenance are equally important. With proper care, a moka pot can stay with you for many years; with improper care, not only will its lifespan be shortened, but it will also absorb odors and affect the flavor of your coffee. Moka pots on the market are mainly divided into two types: aluminum and stainless steel, and different materials require very different cleaning methods.
