Filter coffee (pour-over, drip, or vacuum pot) is not merely a culinary art; it is a multi-phase transport phenomenon. From the moment hot water touches ground coffee, you are witnessing diffusion, advection, capillary action, and thermal degradation kinetics. This article serves as a definitive resource, condensing the core chapters of what would be found in a high-level , including equations, phase diagrams, and actionable brewing protocols.
