Extraction is the movement of solutes (sugars, acids, lipids, caffeine) from the solid coffee cell into the liquid water.

J=−DdCdxcap J equals negative cap D the fraction with numerator d cap C and denominator d x end-fraction is the diffusion flux. is the diffusion coefficient (temperature-dependent). the physics of filter coffee pdf full
The brewing process of filter coffee involves the flow of hot water through a bed of coffee grounds, which is a porous medium. The fluid dynamics of this process can be described by Darcy's law, which relates the flow rate of a fluid through a porous medium to the pressure gradient and the properties of the medium.

Brewing filter coffee involves a combination of physical processes that work together to extract the flavors and oils from coffee beans. The journey of coffee from bean to cup can be broken down into several stages: roasting, grinding, brewing, and finally, dripping.
For example, one PDF shows that a 10% variation in particle size distribution leads to a 4% variation in extraction yield—enough to move a coffee from "excellent" to "meh." is the diffusion coefficient (temperature-dependent)
For those seeking a more budget-friendly option, it is also available in many public and university library systems, often in both physical and digital (e-book) formats. Check your local library’s online catalog, or WorldCat to find a copy near you.

Once surface solubles are washed away, water must penetrate the intact pore structure of the coffee particle to dissolve the remaining trapped compounds. These dissolved solutes then migrate from areas of high concentration (inside the particle) to low concentration (the surrounding water).
The behavior of water as it flows through the coffee bed dictates how evenly the soluble materials are removed. Fluid Dynamics
