Nailed it! Love this video and the entire series--can't wait for the next one!
Dan, you are a great teacher and I really like how you incorporated the 'quantitative' tips in a creative way. You really clarified something that took me months to figure out on my own--that the espresso range is small! I like your explanations a lot, however, I think it would add more to this series if you let Phillip talk a bit more and share his thoughts. I got the impression he had more comments/questions, but was cut off a few times.
Some small corrections, the first grinder is a Baratza Preciso (sometimes also called a Virtuoso Preciso) which is different than the Baratza Virtuoso. The difference is that the Preciso has a micro adjustment collar (you can see it--the black plastic right under the hopper). Also, the Virtuoso and Preciso have conical burrs.
