After the change, you set the grind size again. For espresso we go by weight, not time, with a 1:2 ratio as a starting point. Our opinion is one of many.

Frequently asked questions
Which grinders do the burrs fit?
According to Mahlkönig, the K32S and the Costa Rica.
When should I replace the burrs?
When the grind becomes uneven despite a clean setting. Service life depends on volume, bean and grind size.
How quickly are the burrs delivered?
Delivery across Switzerland and to Liechtenstein in 2–4 working days. Click & Collect is available in Bern and Zurich Oerlikon.
Tip from the roastery: Fresh burrs are a good moment to dial in again with a familiar bean. For espresso we recommend Cozy Chocolate and Nutty Delight, dense, round and chocolatey. For maximum body without acidity there is Very Nutty. That is our recommendation, one of many.
