Coffee Extraction Physics
A physical chemistry guide to coffee brewing: water chemistry, Darcy's law fluid dynamics, and extraction imbalance solutions.
Discover how magnesium (Mg²⁺) and calcium (Ca²⁺) ions bind with organic acids, how HCO₃⁻ alkalinity buffers pH acidity, and how Darcy's law flow velocity governs extraction yield without channeling.
