Clumps often form in the ground coffee in the portafilter. In recent years, the so-called WDT technique (Weiss Distribution Technique) has been established as a solution to this problem. With the help of needles attached to the wood, all lumps can be broken up with circular and stabbing movements. The espresso distributor can then be used to create a flat surface for roping. This procedure will give you the best extraction!
With this espresso distribution tool you can distribute the ground coffee evenly in your portafilter.
