In this post, I discuss how I pull espresso shots with the EG-1 grinder and SSP’s ultra-low-fines burrs. These shots have a high average extraction yield, high clarity and low mouthfeel.
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”
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 review why I completely switched from the V60 to the Stagg [X] brewer, and how I now use it.
In this post I discuss the effects of coffee varieties, origin and processing on average extraction yield and brew time.
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 discuss issues and possible avenues for grinding finer for filter coffee
This post describes some available tools for measuring water properties relevant to coffee and presents ways and a web tool to hack aquarium kits for a better precision.
