The Struggle for a Steady Kettle Flow

In this post I discuss recent developments in my efforts to stabilize my kettle flow rate.

I just published a blog post on my Patreon going deep into the analysis of 300 particle size distributions for 24 espresso grinders, with a number of observations that they allowed me to make. This was super informative to me and I hope it also is to all of you !

I'm happy to announce I have teamed up with @flairespressomaker and @weberworkshops for a nice giveaway this week; you can win a Flair 58 + Weber Workshops Unifilter along with my book :) follow the link in my bio to enter the giveaway !

I just published a new blog post on my Patreon (link in bio) about particle size distributions, with a discussion of how burr spacing, rpm, burr geometry affects them, and how to characterize different styles of particle size distributions. This is one of my most data heavy posts so far, thanks a ton to @weberworkshops for sharing their data.

I just posted a new blog post on my Patreon (link in bio) about my updated understanding of the mechanisms that I believe cause astringency in coffee, with hints about avenues we might use to reduce it. The post is immediately available on Patreon and will become publicly available in about 2 weeks !

@pullandpourcoffee created yet another awesome visual to convey some of my recent understandings of espresso physics ! I think this phenomenon has often been misconstrued as puck erosion or degradation, whereas this will happen in even the most well behaved espresso shots !
