Why Your WDT Tool Fails? Fix Needle Density in 1 Minute!
WDT (Weiss Distribution Technique) tools are designed to improve the distribution of coffee grounds in your portafilter before tamping. However, if the needles on your WDT tool are too tightly packed together, they may unintentionally push the coffee grounds to the side, creating hidden clumps that can negatively affect the consistency and quality of your espresso. These clumps can cause uneven extraction, resulting in under-extracted or over-extracted flavors in your cup.
