This grinder has made a huge and immediate difference in the way I roast, grind, brew and drink coffee.I first tested it with CITY+, FULL CITY and FULL CITY+ roasts of the same coffee. I immediately noticed the CITY+ roast to be my favorite by far. About midway between first and second crack. I also noticed pour over brewing brought out flavors I had only hoped for before. It was very easy and quick to achieve a new level of enjoyment for my coffee drinking. I only wish I would have bought one of these earlier.
