Dye Colored Espresso Shots

Adding dye to espresso shots

In the Before Times, I was looking at different ways to understand flow during the shot. If only there was a way to see how the water went through the puck. It suddenly dawned on me that I could try color dyes.

First Test

I used four different dyes around the shot.

Second Shot

I had been pulling 14g shots in a 7g basket so as to remove the headspace of the filter. Many of these were staccato shots.

Third Shot

More color!

Fourth Shot

More colors plus a red dot.

I’m in love with my Wife, my Kids, Espresso, Data Science, tomatoes, cooking, engineering, talking, family, Paris, and Italy, not necessarily in that order.
