The Science Behind Coffee

The Physics of Filter Coffee, written by astrophysicist Jonathan Gagné, is an excellent resource for all those seeking to dive deeper into the manual coffee rabbit hole. In this book, Gagné discusses the physics behind percolation, extraction, grind particle size, paper filters, and water chemistry. Gagné also touches on differently designed kettles and how pouring turbulence and agitation affects overall extraction and the resulting flavor of your coffee. All in all, this book will equip baristas at any level with practical knowledge on how to make better coffee.
