Filter coffee (pour-over, Chemex, V60, or automatic drip) is fundamentally a . Water flows through a porous medium (ground coffee), dissolving soluble compounds. The goal is to achieve a specific Total Dissolved Solids (TDS) percentage—roughly 1.15% to 1.35% for optimal flavor according to the Specialty Coffee Association (SCA).

In the world of specialty coffee, we often speak in terms of artistry. We talk about the "hand" of the barista, the "craft" of roasting, and the "art" of the pour. But underneath the romantic veneer of bubbling kettles and paper filters lies a rigid, unyielding world of mathematics and thermodynamics. Filter coffee (pour-over, Chemex, V60, or automatic drip)
Key concepts in thermal physics include: If you have been searching for , you
A finer grind reduces permeability (( k )), slowing flow and increasing contact time, which raises extraction. But go too fine, and you create a hydraulic blockage (channelling).
