WDT Tool
The Weiss Distribution Technique, also know as WDT, tool is made of genuine rose wood with stainless steel needles.
This is a much more elegant replacement to your homemade tool made with a wine cork and paperclips! Using this tool will help break down the clumps and evenly distribute the espresso in your portafilter to promote even extraction and overall better espresso.
