Maintaining a stable thermal profile throughout the brew cycle is crucial. When water is poured onto a cooler coffee bed, energy is absorbed by the grounds and the brewing vessel (e.g., ceramic or glass drippers). If the temperature drops significantly, the extraction of sweetness and heavier sugars stalls, leaving the brew sour and under-extracted.

The brewing process can be broken down into several key stages:
During a pour-over brew, heat is constantly lost to the environment through radiation, conduction into the brewer material (glass, ceramic, or plastic), and evaporation. Plastic brewers actually exhibit the lowest thermal conductivity, meaning they retain heat within the coffee bed better than ceramic or glass, yielding a more thermally stable extraction. 4.

To understand why the is so valuable, you must understand the physics inside:
The flow rate is determined by the permeability of the coffee bed, the pressure drop across the bed, and the fluid viscosity. If the grounds are too fine, the spaces between particles shrink, permeability drops, and the water stalls, leading to over-extraction. 2.

Diffusion is the random movement of particles from an area of high concentration to an area of low concentration. In the case of filter coffee, the flavors and oils in the coffee grounds diffuse into the water, creating a concentration gradient.
