Tip from the roastery: The knob sets the grind size, the bean does the rest. For espresso we start with a brew ratio of 1:2 by weight and adjust to taste. For most cups we recommend Cozy Chocolate and Nutty Delight, dense, round and chocolatey. For maximum body without acidity there is Very Nutty, and if you want to discover something fruity, you will find it in Wild Peach. That is our recommendation, one of many.
