The Physics of Filter Coffee by Jonathan Gagné is perhaps the most significant book ever written on brewing filter coffee!
In the book, Jonathan explores the physics of percolation, extraction, and grinding, as well as water chemistry. He takes the reader into details such 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. He also presents some of his original ideas about coffee brewing and backs everything up with plenty of facts and data.
Simply put, if you want to take your filter brewing to the next level, this book is a must-have.
