The Physics of Espresso is for everyone who wants to understand espresso not as a mystery, but as a system governed by clear physical laws. Jonathan Gagné breaks down every step: water chemistry, grinding, extraction, pressure and flow profiling, the dynamics of a shot and even how to store your coffee.
Based on hands-on experiments and published scientific data, and illustrated with hundreds of graphs, drawings and photos, the book gives you concrete tools to improve your espresso, whether you are a professional barista, a roaster or a passionate home brewer.
Jonathan Gagné is an astrophysicist at the Rio Tinto Alcan Planetarium in Montreal and a coffee perfectionist. On his blog Coffee ad Astra he has spent years testing, measuring and explaining coffee brewing with the rigour of a scientist.
Why every coffee lover wants this:
