The Physics of Filter Coffee is a deep dive into the science behind coffee brewing. In the book, renowned astrophysicist Jonathan Gagné brings welcome scientific expertise to coffee making. Not only does the book contain numerous original ideas about coffee brewing, but Jonathan lays to rest many controversial ideas about coffee making.

I set out with the goal to understand the ways in which the roast profile affects the flavor of the coffee. Through a large amount of research and experimentation, I have developed what I would consider a unified theory of coffee roasting with regards to how it affects the flavors being developed in the bean. This has helped me understand and intentionally manipulate the flavor of coffees that I am roasting since. I hope it will be as beneficial a paradigm for you as it has for me.
