Original Fiorenzato single dose bellows for the AllGround grinder: it mounts in place of the standard bean hopper and turns the AllGround into a single dose setup. Load the beans for one drink (up to 50g), grind, then give the bellows a couple of pumps: the puff of air pushes residual grounds out of the chamber and chute, cutting retention to a minimum.
It is the simplest way to get fresh, weighed doses from your AllGround if you rotate different coffees through the week, with no stale grounds from the previous bag ending up in the cup. Fiorenzato part number 900001669.
