The Barista Pro Gear Clump Crusher is a Weiss Distribution Technique (WDT) Tool designed to break up any clumps of ground coffee and even out the coffee density within the bed. This will result in reduced channelling during espresso extraction and a significantly more even extraction at that.
There are many coffee distribution tools available on the market, but the Clump Crusher is by and far the best bang-for-buck tool you can get in the field of distributing tools.
Di Bartoli recommends pairing the Clump Crusher with the Barista Pro Gear Dosing Ring 58mm if you have a 58-58.5mm sized basket
