The Physics of Filter Coffee
The Physics of Filter Coffee by astrophysicist Jonathan Gagné is perhaps the most significant book ever written on the science of coffee brewing.
Any barista who reads this book will immediately have new tools to make better coffee. Jonathan discusses the physics of percolation, extraction, and grinding, as well as water chemistry. He takes the reader down such rabbit holes as pouring-kettle design, optimizing turbulence while pouring, the impact of fines on percolation, the physics of paper filters, and the geometry of various brewers.
This book offers an abundance of practical recommendations derived from science, data, and experimentation.
