The LUCCA WDT tool is here to save your coffee. WDT stands for Weiss Distribution technique, and it is designed to distribute the entire coffee bed evenly and remove any boulders and clumps from the grinding process. Even distribution + fluffy espresso grounds = better-tasting coffee. The LUCCA WDT tool includes 8 surgical-grade needles at 0.4mm thickness and a stainless steel tool stand. Pair it with the LUCCA Dosing Funnel to mitigate spillage.
