As the water flows through the coffee grounds, it extracts flavors, oils, and other compounds through a process known as mass transfer. This process involves the transfer of mass from the coffee grounds to the water, driven by the concentration gradient between the two.

: Swirling or stirring disrupts the boundary layer to increase diffusion rates.

When channeling occurs, the water rushes through the channels, over-extracting the coffee along those pathways and leaving the rest of the bed under-extracted. This results in a bitter yet sour cup. 4. Thermodynamics: Energy and Solubilities

The Physics of Filter Coffee by Johnathan Gagne — Scott Rao

The extraction of flavors and oils from the coffee beans is a mass transfer process. The solutes in the coffee beans, such as sugars, acids, and solids, are transferred to the water through diffusion and convection.

In the case of filter coffee, the porous medium is the coffee grounds, and the fluid is the hot water. As the water flows through the coffee, it encounters resistance due to the friction between the water and the coffee grounds. This resistance can be described by the Darcy-Weisbach equation, which relates the pressure drop across the coffee grounds to the flow rate and the properties of the grounds. As the water flows through the coffee grounds,

To understand the physics inside the coffee bed, aiming to create a more consistent, efficient, and reproducible brew.

As water temperature rises, its viscosity decreases. "Thinner" water can penetrate the microscopic pores of the coffee grounds much faster, accelerating the internal diffusion phase. 5. The Mechanics of the Filter

The specific that proves which brewer is more consistent? The Physics of Filter Coffee w/ Jonathan Gagné | Ep 350

Gagné identifies extraction as the primary goal of brewing—drawing soluble matter (acids, sugars, and eventually bitters) from ground coffee into water.
