My La Cafetiere manual grinder has started grinding v v slowly - just under 5mins for 17g of beans, fairly course for French Press. It feels like the burrs aren't biting/cutting into the beans nearly as quick as they should be.
Could the burrs be blunt already? Under 6 months of use... Or anything else I should consider? (I've tried more than one lot of beans - so I don't think this is just awkward beans)
