Physics – Coffee ad Astra

More Even Espresso Extractions

In this post, I talk about ways in which I have recently improved my puck preparation for espresso.

I come back to my last experiment and explore whether the difference in gravimetric vs volumetric flow could be due to changing shot TDS.

In this post, I compare several shots pulled with the Niche to others pulled with the EG-1 and SSP ultra-low-fines burrs.

In this post, I lay down four rules for optimal percolation that follow some of my most recent understanding about percolation physics.

In this post, I present an experiment showing that deep WDT helps improve repeatability, and I discuss how to improve espresso preinfusion.

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.

In this post, I discuss the physics of kettle stream and how we can maximize extraction evenness by changing pour rate and height.

In this post, I explore the details of physical phenomena that can cause fines to migrate and clog coffee filters.

In this post, I show that surface hardness might vary more than mass density across different green coffees.

In this post I discuss the variables that affect brew time in detail
