Tip from the roastery: The flapper is a small part inside the grinder. What reaches the cup is decided by the bean. For most cups we recommend Cozy Chocolate and Nutty Delight, dense, round and chocolatey. 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.
You order directly through our online shop. If you have questions, we're happy to help — online or in person — with experience from our roastery, cafés and showrooms.
