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 anContinue reading “How a Paper Filter Below an Espresso Puck Affects Hydraulic Resistance”

Brewing with the Fellow Stagg [X] Dripper
In this post, I review why I completely switched from the V60 to the Stagg [X] brewer, and how I now use it.
The Physics of Kettle Streams
In this post, I discuss the physics of kettle stream and how we can maximize extraction evenness by changing pour rate and height.
Why Can’t we Grind Coffee Finer for Pour Over ?
In this post, I discuss issues and possible avenues for grinding finer for filter coffee
The Physics of Fines Migration
In this post, I explore the details of physical phenomena that can cause fines to migrate and clog coffee filters.

In this post I discuss recent developments in my efforts to stabilize my kettle flow rate.
What Affects Brew Time
In this post I discuss the variables that affect brew time in detail
An Investigation of Kettle Temperature Stability
In this post I investigate the stability of my Brewista kettle with the Brewcoat insulation and an additional layer of aerogel.
Why do Percolation and Immersion Coffee Taste so Different ?
In this post, I discuss the physics of extraction by percolation and immersion and how they lead to very different taste profiles.
A V60 Pour Over Video
Today I decided to release publicly one of the V60 videos from my Patreon. I plan to make a better quality video eventually for my blog, but in the meantime I thought this would be interesting to a wider audience. Please view this recent post I made about what is going on with Patreon ifContinue reading “A V60 Pour Over Video”
