The Physics of Filter Coffee: Why Your Next Brew Deserves an Equation

Title: The Physics of Filter Coffee by Jonathan Gagné
Format discussed: EPUB (Digital workflow & practical application)

• V60 / pour-over baseline (example): 16 g coffee : 256 g water (1:16), 92°C kettle, 30–45 s bloom with 40 g water, then pulse pours to reach 256 g at 3:00–3:30 total.

  • Extraction as dissolution from particle surfaces into flowing solvent: combination of diffusion within particles and advection in pores.
  • Two-resistance model: internal diffusion inside particles and external mass transfer across boundary layer.
  • Rate-limiting steps depend on particle size, flow velocity, and temperature.
  • Typical behavior: fast initial extraction of acids, sugars; slower extraction of bitter compounds and heavier solubles.
  • Modeling approaches: empirical brew-strength models; mechanistic models using diffusion equations with appropriate boundary conditions.
• Suggested target: EY 18–22% and TDS 1.15–1.45% as a starting range (taste-dependent).
