Brewtool Coffee Needle WDT Tool

Description

The WDT’s purpose is straightforward. When coffee is ground, it has a tendency to clump together, particularly when it’s ground really finely, like for espresso. This results in uneven distribution of the ground coffee in, in this instance, your portafilter. This can cause channeling, where water takes the easiest route through the coffee puck, causing a mix of under-extracted and over-extracted areas. This in turn leads to an imbalanced and inconsistent flavor.

A solid tap on the side of the portafilter addresses the distribution challenge, to some extent, but only goes so far. The latest approach to solving the problem of channeling is the Weiss Distribution Technique (also WDT) which breaks up the coffee using fine needles. The extra fine needles of Brew Tool’s Coffee Needle help to more efficiently break up these clumps as you run it through your coffee puck prior to tamping, resulting in more even distribution, better extraction, and more delicious espresso.
