👇 What is a WDT Tool?
WDT TOOL
A WDT tool (short for Weiss Distribution Technique) is a simple device with fine needles that help evenly distribute ground coffee in your portafilter. It’s designed to break up clumps and create a uniform puck — which means better extraction and less channeling.

🛠️ What You’ll Need
- Freshly ground espresso coffee
- A portafilter
- Your WDT tool
- Tamper
- (Optional) Dosing ring or funnel
Tip: A dosing funnel helps keep things tidy during this step.
📋 Step-by-Step: How to Use a WDT Tool
1. Grind Your Coffee into the Portafilter
Start by grinding your dose directly into the portafilter. If your grinder clumps a bit — no worries — that’s exactly what the WDT tool is here to fix.
2. Stir the Grounds with the WDT Tool
Use the WDT tool to gently stir the coffee bed in small circular or back-and-forth motions. Your goal is to break up clumps and distribute the grounds evenly.
- Keep the tool slightly above the bottom of the basket.
- Focus on reaching all areas — edges and center.
- Work for 5–10 seconds until the coffee bed looks even and fluffy.

3. Settle the Bed (Optional)
Tap the portafilter gently on the counter or settle the grounds by giving it a light shake. This helps create a flat surface before tamping.
