The WDT Tool (Weiss Distribution Technique) has become a popular accessory among coffee enthusiasts and baristas. This tool is used to distribute the coffee grounds evenly in the portafilter before brewing and has been proven to improve the quality and consistency of coffee extraction. But what are the benefits of a WDT tool, how is it used and what are the best WDT tools on the market?
What is a WDT tool?
A WDT tool is a simple device used to evenly distribute coffee grounds in a portafilter. It is named after Chris Weiss, who first documented and disseminated this technique online. The device usually consists of a handle and a series of thin wires or needles that are used to break up clumps and distribute the coffee grounds evenly in the basket.
Advantages of using a WDT tool
There are several advantages to using a WDT tool when brewing coffee, including:
- Uniform extraction
By evenly distributing the coffee grounds, the WDT tool ensures that the water flows evenly through the coffee bed, resulting in a balanced and even extraction.
- Less waste
By breaking up lumps, the WDT tool helps prevent over- or under-extraction, which can lead to wasted coffee grounds.
How do you use a WDT tool?
