  • Description
  • Specs
  • 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 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.

Great book, and great service from 8oz, thx!

Daniel C. (California, United States)
Wonderful book full of information.

The book is packed with different topics and data, for me, it is a perfect gift for a physics student.

Must read for someone who wants to dig deep

This book goes in very specific details on how coffee is extracted. This is a must read for someone who wants to truly understand physics of extraction

Superb deep dive

Love that Gagne doesn’t shy away from getting technical about coffee, brewing methods, and equipment. Not much practical instructions but it’s not meant to be that. Instead you are given tool to help deepen your understanding which may help guide your own technique in brewing coffee.

my husband loves his book

he spent the whole holidays reading it before bed, and was so excited about the things he was learning. there is enough nerdy data for those who want and enough well-summarized and explained information for those who can't haha!

Ron R. (Ohio, United States)
Extensive and Deep Book

This is a great reference book for the how behind filter coffee. It goes into considerable detail regarding the Physics behind brewing coffee. I will say that although well written, it is fairly technical in nature. Some might not like that much of a technical deep dive. For me, it is right up my alley. I'd like to emphasize that although technical, it is written in such a way so as to make it a good read. I strongly recommend the book. This is a recognized reliable source of information from a key figure in the coffee & scientific worlds. Well done!
