Magnetic WDT Tool:

WDT tool, which stands for "Weiss Distribution Technique" or "Weiss Distribution Tool," is primarily used in the process of preparing espresso. Its main function is to evenly distribute coffee grounds within the portafilter basket before tamping. This even distribution helps to ensure consistent extraction of flavors and aromas during the espresso brewing process.

Here's how the WDT tool works:

1. After dosing the coffee grounds into the portafilter basket, the barista uses the WDT tool to gently agitate and level the grounds.
2. The WDT tool typically has a series of thin, evenly spaced needles or prongs that penetrate the coffee bed, breaking up clumps and redistributing the grounds.
3. By using the WDT tool, baristas aim to achieve a uniform distribution of coffee grounds throughout the entire surface area of the portafilter basket.
4. Once the grounds are evenly distributed, the barista then proceeds to tamp the coffee bed with a tamper to compact the grounds before brewing the espresso shot.

Overall, the use of a WDT tool helps to improve the consistency and quality of espresso extractions by ensuring that water flows evenly through the coffee bed during the brewing process.
