The particle size distribution of the coffee grounds affects the porosity of the coffee bed and the flow rate of the brewing water.

Extracting flavor compounds from solid coffee matrix into water relies on two consecutive physical phenomena: dissolution and diffusion. The Two-Stage Extraction Mechanics the physics of filter coffee pdf full

Temperature is a primary driver of extraction kinetics. The diffusion coefficient ( The particle size distribution of the coffee grounds

As water flows downward, microscopic fines migrate with the current and settle at the bottom of the filter. This plugs the pore spaces, reduces permeability, and slows down or stalls the flow ( the physics of filter coffee pdf full
