In coffee competitions, double grinding was once seen as a means of precisely controlling particle size, but the actual practice is far from simple. Sending coffee grounds through the grinder again not only multiplies the amount of fines, but also worsens the "retention" problem—especially in electric grinders, where it can leave a large amount of grounds behind, making cleanup time-consuming and laborious. This article uses Front Street's experimental data to analyze in detail the impact of double grinding on the grinder, compares the differences between electric and hand grinders in this process, and offers alternative extraction adjustment solutions to double grinding, helping you improve extraction efficiency without disassembling your machine.

When ordering at a coffee shop, have you ever noticed the filter basket the barista uses? A single basket typically holds 9–11g of coffee grounds for pulling a single espresso; a double basket can hold 18–22g for a double espresso.

If you accidentally grind your coffee too coarse while making pour-over, can you pour it back into the grinder and grind it finer? This is what's known as re-grinding. Although it's used in professional competitions to improve particle uniformity, it also brings two major problems: an increase in fines and grinder retention. Through experiments, Front Street Coffee found that after re-grinding, nearly 20 grams of grounds might be reduced to only about 13 grams—a shocking loss. If you don't have tools like a bellows, you might want to try a different approach: directly adjust parameters such as water temperature and pouring method, and use the coarser grounds to brew a good cup of coffee. This article uses Panama Elida Anaerobic Natural Catuai as an example to share a specific brewing plan, so you can handle unexpected situations with ease. [more…]
