Restraining Flow to Mitigate Channels

In the past weeks, I have been experimenting with the AeroPress combined with the Prismo attachment, and I tried one small hack that produced a surprising result. I inserted a pasta strainer mesh like the one I described in my Stagg [X] recipe to increase the total open surface area under the AeroPress filter.

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