In this video Luke is talking all about the WDT barista tool. He's explaining exactly what it is, what it is used for and how to use it.
WDT is an acronym for Weiss Distribution Technique but has also become known as the Weiss Distribution Tool. Essentially the WDT is a tool with fine needles that a barista uses to stir coffee grinds around while they sit in the portafilter. Stirring with the fine needles breaks up any clumps, and evens out the density of coffee within the puck. Adding this technique to the coffee puck preparation process aids in reducing channeling, and produces higher quality and more even extractions.
We hope you enjoy the video and it helps you understand what the WDT is all about.
