Hi @deleted user ! That is a great question. I am a hands-on learner, so when I was in training to become a bartender, I had a really great mentor who would have me practice all the drinks with mock bottles (they were emptied out bottles filled with water) so that I could get used to pouring at different weights and could learn my "counts" of pours so I could get quicker and more accurate. It was very helpful and I thought it was a unique way to train instead of just memorizing words from a piece of paper. What about you?
