Some coffee enthusiasts might think: since a grinder can grind coffee beans into fine powder, grinding already-ground coarse powder finer again should not be a problem, right?

Many coffee enthusiasts are often puzzled when tasting pour-over: why are fruity notes like citrus and pineapple easy to identify, while the sweet aromas of strawberry and peach always seem veiled? Front Street approaches this from the perspective of aroma chemistry composition and concentration differences, revealing the fundamental reason these fresh fruit notes are hard to capture—authentic strawberry aroma is presented through the synergy of over three hundred volatile compounds, while coffee contains only a small amount of similar components. The article proposes two paths to solve this: first, training the sense of smell to capture secondary aroma contours beyond the primary notes; second, amplifying target flavors through high-temperature fast extraction and appropriately diluting the coffee-to-water ratio in brewing strategy. Front Street also lists several sun-dried bean options with peach and strawberry notes, and using Ethiopia Hamashu as an example, provides complete brewing parameters and tasting records. [more…]

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.
