Tip from the roastery: A grinder that runs reliably grinds the same bean anew every day. For dense, round espressos with chocolate and nut we roast Cozy Chocolate and Nutty Delight. For maximum body without acidity there is Very Nutty, and anyone who wants to discover something fruity will find it in Wild Peach. That is our recommendation, one of many.
