Do I have to use a coffee filter?
Yes! For your convenience, we pack our green beans in a biodegradable coffee filter. But if you are using loose green coffee beans that are not in our pouches pouches, use about 3 tablespoons (45-50g) per roast ideally with a Melita filter, or failing that, #2 or #4 paper or gold filter. And remember: You absolutely should not use more than 80g of green beans with your Berlin -- we're all about pushing boundaries here at Bonaverde, but even we have our limits!
