This physics principle describes the flow of a fluid through a porous medium. It tells us that the flow rate is determined by the pressure applied (gravity), the permeability of the coffee bed, and the viscosity of the liquid.
The coffee grounds themselves also play a critical role in the brewing process. The size and distribution of the grounds affect the flow of water through the filter, as well as the surface area available for extraction. A finer grind will result in a slower flow rate and a more even extraction, while a coarser grind will produce a faster flow rate and a less even extraction. The Physics Of Filter Coffee Pdf
Flow rate is directly proportional to the square of the particle size. If you double the grind size, the flow rate increases roughly four-fold. This physics principle describes the flow of a
“It means,” he said, pouring the rest down the sink, “that the physics of filter coffee is a one-time pad. You read it, you make it, you lose it. And all that’s left is the PDF’s ghost—a memory of perfection you can never replicate.” The size and distribution of the grounds affect
