Physics of Filter Coffee - Jonathan Gagné
The Physics of Filter Coffee by astrophysicist Jonathan Gagné is perhaps the most significant book ever written on the science of coffee brewing. In the book 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. He also presents some original ideas about coffee brewing and backs it all up with reams of facts and data. The most wonderful thing
