No grinder is perfect. Every "setting" produces a mix of large particles (boulders) and tiny dust-like particles (fines). the physics of filter coffee epub updated
Smaller grind sizes increase total surface area and decrease the distance water must travel to reach the center of a particle, speeding up extraction. 2. Fluid Dynamics: The "Percolation" Effect You are likely looking for the work of
One of the most overlooked aspects is heat loss. If your slurry (water + coffee) drops below 190°F (88°C), extraction slows exponentially. Smaller grind sizes increase total surface area and
