The Physics of Filter Coffee (POFC) by astrophysicist Jonathan Gagné is perhaps the most scientifically-based book written on the science of coffee extraction. Topics covered include physics of percolation, extraction, and grinding, as well as water chemistry. Jonathan further indulges us with niche topics 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. Original ideas are presented about coffee brewing and backed up by facts and data.
"The most wonderful thing about The Physics of Filter Coffee is not the impressive depth of the science, but the practical lessons Jonathan draws from the science. Unlike, say, Illy’s Espresso: the Science of Quality, an impressive treatise on the science of espresso, The Physics of Filter Coffee offers an abundance of practical recommendations derived from science, data, and experimentation. Any barista who reads this book will immediately have new tools to make better coffee." - Scott Rao Website
