DISTRIBUTE GRINDS EFFECTIVELY - Improve the consistency of coffee extraction with this espresso distributor. The needles effectively break up clumps and evenly distribute grinds in the portafilter as you rotate, improving the brewing taste. REDUCE CHANNELING & INCREASE FLOW - Sometimes an espresso shot can be weak and sour, which is a sign of channeling. Before tamping, use this espresso leveler so water can evenly flow through espresso grinds at a consistent rate for the perfect shot. QUICK & EASY CLEANING - We think of everything and have designed a special holder for this needle distribution tool to make cleaning easy. Simply place the distributor into the bristle brushed base and the residue is swept away.
