This tier includes both grinderless and grinder-integrated machines, but every machine still commits you to a group size and fitting style. We group by passport-backed accessory ecosystem support instead of ranking features we have not tested.

Group placement comes straight from our machine passports. Within each group, machines are ordered by beginner-friendliness, then by name when scores tie - not by price or review scores.

means a marketplace listing asserts the fit; it is not manufacturer-confirmed. Verify size against your
machine before purchase.
