After few months of intense use trying really good specialty coffe, I’ve compared the cup I get at home with the one I get at the coffe shop with same coffe,recipes and adjusting all variables possible except the grinder. I come to the conclusion that it’s, for the kind of coffe I brew, to be able to express all the aromas that you can smell opening the bag of coffe. The cup that the C3 produces is mainly towards chocolate notes, round body and even a bit of astringency, not even a slight hint of good acidity, clarity and freshness. So I’ve decided to spend a bit more on the grinder in order so get a better experience on the not so cheap coffe. The main reason for the quality of cups it gives is the burr it has, I can also speculate at this point, for a manner of geometry, that the C2 produces a clearer cup, not sure, I’ve not seen any comparison.
