Last week, Front Street Coffee shared nine details about brewing coffee, among which it mentioned that the grinder needs to be cleaned regularly. So a reader followed up with the question: Can a grinder actually be washed with water? To answer this question, we first need to understand the necessity of cleaning the grinder. The common grinding equipment on the market falls into two categories: manual and electric. Regardless of which type, the daily upkeep and regular maintenance of the burrs directly affect the service life. Accumulated coffee grounds not only cause flavor cross-contamination, but may also clog the passage. This article will detail the cleaning methods for manual and electric coffee grinders across three levels: daily quick cleaning, cleaning without disassembly, and regular deep cleaning, and will also remind you of the applicable conditions and precautions for washing with water.

Once a grinder lacks regular maintenance, even the highest-end model will age faster. This article focuses on several practical problems most commonly encountered by coffee enthusiasts: how to safely handle a jammed grinder, whether a grinder can be rinsed directly with water, the correct way to remove the burrs, and, using the Ek43 as an example, the deep cleaning and daily maintenance process. The article also combines Front Street Coffee's equipment experience to offer actionable maintenance suggestions that help you extend your grinder's lifespan and keep output consistent. [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 the most difficult part of pour-over parameters to master. Front Street Coffee uses an 80% pass rate through a No. 20 sieve as a beginner-friendly calibration baseline, but different grinders vary enormously in performance, and the same sieve pass rate can produce drastically different flavor outcomes. This article centers on grind calibration: it first explains the limitations of the sieve method and the particle size distribution characteristics of uniform grinders such as the EK43s, then offers remedies for poor-quality grinders, including hand grinder RPM control, the pull-back technique for staged grinding, and the direction for adjustment when too many fines cause off-flavors. Finally, it discusses the criteria for deciding whether sieving is necessary and the practical technique of a single-pour flush to wash away fines, helping you find the grind parameters that suit you.
