On today's show e are talking with the author of the new book, "The Physics of Filter Coffee", Jonathan Gagné! Scott Rao is one of the most accomplished and respected consulting professionals in the specialty coffee space. "Some experiments with very different profiles of particle sizes led me to understand that the smallest particles have a disproportionate impact on how easily the flow of water will flow through a bed of coffee. It can be extremely surprising how different a cup of coffee can taste by only changing the method of extraction, with the same bag of coffee. 148: Exploring the Ground Control Brewer w/ Eli Salomon.

It is hard to push such a viscous fluid through a coffee bed, and as the shot progresses, the concentration will drop by a large amount and it will become gradually easier to push the coffee through, meaning that either the pressure will go down or the flow rate will go up. He presents himself as a researcher in astrophysics and a passionate coffee geek, with a blog called Coffee Ad Astra and author of the book The Physics of Filter Coffee. Softcover, 244 pages.
