I got the idea of pulling a shot into a cold cup from a few different discussions here that brought up the temp of espresso and how people enjoy/find different flavors at different temps. This got me thinking, as someone who generally thinks that most coffee is served at too high a temp, maybe I should look into this.
My first experiment was to pull a shot into a cup straight out of the freezer. Very interesting! I am going to keep my findings to myself for now so I don't influence others if they want to try this (I encourage you to).
