Collection: WDT (Weiss Distribution Technique)

Why WDT tools matter

The secret to a great espresso shot starts long before you press the brew button. WDT (Weiss Distribution Technique) tools break up clumps and even out your coffee bed so water flows through every particle evenly, giving you sweeter, more consistent shots.

Most grinders, even premium ones, create clumps and uneven density in the portafilter, which leads to channeling - water racing through weak spots and leaving you with sour or bitter espresso. A WDT tool uses fine needles to gently stir and redistribute grounds throughout the basket, smoothing out density from bottom to top.
This simple step dramatically improves extraction consistency, helping your grind and tamping work the way they’re supposed to and making it easier to repeat great shots.

Why choose Coffee Plus WDT tools

The Coffee Plus WDT collection focuses on needle quality, spacing, and ergonomics—details that decide whether WDT actually improves your puck or just moves clumps around. You get fine, springy needles, comfortable handles, and designs that avoid scratching your basket while reaching all the way through the coffee bed.
From minimalist hand tools to more advanced needle distributors, this range gives both new home baristas and pros a reliable way to unlock more clarity, sweetness, and balance from their espresso.

We stock advanced gear like magnetic telescopic tools that protect your needles and your countertop. Unlike makeshift paperclips, our tools use medical-grade stainless steel needles with the perfect thickness (0.25mm-0.4mm) to fluff grounds effectively.

Built for consistency and compatibility

These tools are designed to work with common basket sizes (51–58 mm) and standard portafilters, so you can use the same WDT tool across multiple machines if needed.
High‑quality stainless needles and robust handles stand up to daily use, while thoughtfully shaped tips or loops reduce the risk of scraping metal and help the tool glide through the grounds instead of compacting them.

How to use your WDT tool

Step‑by‑step WDT routine

1. Grind into your portafilter as usual, then place it on a tamping mat or stand so it’s stable.
2. Insert the WDT needles into the coffee bed, reaching close to the bottom of the basket, and gently stir or swirl to break up clumps and loosen any dense pockets.
3. Gradually move your motions upward, finishing with lighter, more horizontal passes near the surface to level the grounds.
4. Lightly tap the portafilter on the mat to settle the coffee, then follow with your distributor (if you use one) and tamp straight down once.

Used this way, WDT becomes a fast, reliable step that significantly reduces channeling and tightens your shot‑to‑shot consistency.
