Must-read for espresso nerds

Dense but surprisingly readable for math/physics/coffee geeks like myself. If you want to understand what's happening in your cup, this is a very interesting book!

After reading the Physics of Filter Coffee and enjoying that I decided to pick this up as well. Gagne wrote this newer book in a more easy to digest way in my opinion and I am thoroughly enjoying the book so far. Very dense, but great if that is what you are into.
