Coffee contains over 1,800 chemical compounds, but key flavor contributors include organic acids (bright, fruity), sugars (sweetness), chlorogenic acids (astringency), and caffeine (bitterness). The solubility of these molecules increases with temperature. According to the Van 't Hoff equation, a 10°C rise typically doubles the reaction or dissolution rate. Water at 93–96°C (recommended for light to medium roasts) rapidly solubilizes desirable acids and sugars. Water below 80°C yields sour, weak coffee (under-extraction), while water at boiling (100°C) aggressively extracts tannins and bitter quinic acid (over-extraction). $$ J = -D \fracd\phidx $$ " doesn't

The Physics of Filter Coffee elevates the barista from a cook to an experimental physicist. It suggests that by measuring (using a refractometer to find Total Dissolved Solids) and charting the Extraction Yield , we can move away from "guessing" and toward a repeatable, objective standard of deliciousness. The solubility of these molecules increases with temperature

Pour slowly in concentric circles (Rao’s "spin pour") to ensure uniform fluid velocity across the bed.
