A WDT tool is a device that is used in the process of making espresso. The name WDT came from John Weiss who introduced the technique; it is a device made to help baristas and coffee lovers have more consistent extraction by ensuring even distribution of coffee grounds in the portafilter basket prior to tamping. This single step can have a significant impact on the quality of your espresso shot leading to a tastier and more balanced cup of coffee.
Purpose and Function
The main purpose of having a WDT tool is to break up clumps of coffee grounds and distribute them evenly across the portafilter basket. Fine grinding, especially for espresso, leads to static electricity that causes clumping together due to attraction between particles’ surfaces and the natural properties exhibited by coffee. These lumps can cause uneven extraction that results in undesirable flavours such as bitterness or sourness.
The WDT tool solves this problem by mixing up the grounds so that all lumps are gone while creating a uniform layer of coffee grains in your portafilter. Check out our collection of WDT tools; Barista Progear Clump Crusher, Pullman Stir WDT Tool, Barista Progear WDT Tool, or Barista Hustle Comb.
Design and Components
Generally, a WDT tool has two parts: its handle and many thin needles or wires. These needles are usually made from long-lasting materials like stainless steel and arranged in a way that can penetrate and stir the coffee grounds. Some WDT tools have adjustable needle lengths and configurations to fit different preferences and portafilter sizes.
How to Use a WDT Tool?
Although it might take some time before achieving proficiency with it, using a WDT tool isn’t complicated either. Below are general guidelines:
- Preparations: Start by grinding your coffee beans to the desired fineness for espresso. Ensure that your portafilter is clean and dry.
- Distribution: Put your ground coffee into the basket of the portafilter. Using the WDT tool, stir the grounds in a circular motion. Break up the clumps and distribute the grounds evenly in the basket. Don’t compact the grounds too much as this will affect the tamping process.
- Tamping: Proceed with regular tamping after using the WDT tool. This step compresses the coffee into one consistent puck so that water extraction is even.
- Extraction: Put the portafilter in the espresso machine and start the extraction. You should get a more consistent and balanced espresso shot.
