Hello all ! I am so thrilled to announce that my second book The Physics of Espresso is finally out ! This one took a while longer than I expected, and you’ll understand why when you get your hands on it. It contains hundreds of graphs and drawings, more professional photos and both my editorContinueContinue reading “The Physics of Espresso is out !!”

More Even Espresso Extractions
In this post, I talk about ways in which I have recently improved my puck preparation for espresso.
On Gravimetric Measurements of Total Dissolved Solids
I come back to my last experiment and explore whether the difference in gravimetric vs volumetric flow could be due to changing shot TDS.
A Comparison between Standard and Low-Fines Espresso Shots
In this post, I compare several shots pulled with the Niche to others pulled with the EG-1 and SSP ultra-low-fines burrs.
How a Paper Filter Below an Espresso Puck Affects Hydraulic Resistance
In one of my latest posts, I investigated the effect of puck preparation, and in particular the addition of a dry paper filter above the espresso puck, affects the hydraulic resistance of the system during an espresso shot. While I have not yet tested its effect on average extraction yield, I did not see anContinueContinue reading “How a Paper Filter Below an Espresso Puck Affects Hydraulic Resistance”
A Study of Espresso Puck Resistance and How Puck Preparation Affects it
In this post, I present an experiment showing that deep WDT helps improve repeatability, and I discuss how to improve espresso preinfusion.
An Espresso Profile that Adapts to your Grind Size
In this blog post, I explore the possibility of a different way to profile espresso shots with the Decent machine to help dialing in faster.
Measuring the Concentration of Espresso Shots
If you are wondering why it is widely recommended to use syringe filters when you measure the concentration of espresso shots with a refractometer, or how bad exactly a measurement would be if you don’t use such a filter, I highly recommend this recent blog post by my friend Mitch Hale. And while you’re there,ContinueContinue reading “Measuring the Concentration of Espresso Shots”
