I'm a home brewer who's been stuck at "good enough" for years, and Gagné's explanation of percolation dynamics finally made my pour-over technique click. The way he breaks down extraction physics with real equations but keeps it readable is exactly what I needed. My morning cups have been noticeably

As an astrophysicist, Gagné brings a rare level of rigor to explaining extraction, and the chapters on water chemistry and temperature decay really clicked for me. I've read it twice and still catch new details that improve my morning pour-over.

The way Gagné breaks down the percolation process with actual equations made the science click for me—it's not just another recipe book. I've already dialed in a better morning brew after applying just one chapter on water flow.
