Rotating Magnetic WDT Coffee Distribution Tool

The Rotating Magnetic WDT Tool is designed for baristas and coffee enthusiasts who want to take espresso prep to the next level. Using the Weiss Distribution Technique (WDT), it gently stirs coffee grounds in the portafilter to break up clumps and aerate the coffee bed, reducing channeling and helping water flow more evenly during extraction.

With adjustable needle height and a magnetic base for stability, this tool makes it easy to handle different doses and portafilter sizes. Durable construction ensures it will stand up to daily use, whether at home or in a busy café.

By improving coffee bed consistency, this WDT tool helps you extract the true flavour of your beans — without overcomplicating your prep routine.
