In that time, I looked at heating the beans before grinding, cooling the grounds before brewing, tamp pressure, and puck layering (i.e. For home equipment. Two shots with most of the same parameters had different extractions, and once I started tracking pre-infusion with an extra parameter, I discovered a pathway to determining the proper amount of pre-infusion. Correlation doesn’t mean causation, but it gives us a clearer idea of finding a root cause, in this case, how to better utilize PI. $2,995.00.
