Any experienced barista will tell you that WDT tools are the key to making good coffee with even extractions. The Weiss Distribution Technique involves using a thin object (e.g. a dissecting needle) to split up coffee clumps and level out the distribution. Resulting in an evenly extracted shot.
In this article, I have compiled and ranked the most effective Wdt tools available in the market today. But if you’re in a rush, here’s the gist of it:

How Many Types of WDT Are There?
There are three main forms of WDT:
- Puck raking
- Shallow WDT
- Deep WDT
With deep WDT, you place the needles straight to the bottom of your filter basket and start stirring in overlapping circles until you touch all possible clumps.
Shallow WDT involves simply scraping and evening out the top layer of your espresso without going deeper.
Puck raking is where you gently flatten out the mound of your coffee grounds.
Generally, deep WDT tends to be the most effective method out of all three, as stirring directly to the bottom of the filter basket leads to higher puck resistance. So feel free to go deep!
Can You Make Your Own WDT Tool?
Yes, if you are looking for a WDT, you can buy one or make a homemade one. A DIY WDT tool is surprisingly easy to make. In the past, people used a paper clip, hairpin, or needle, but these have been shown to be too thick for proper distribution. The right needles for a good WDT tool should range from 0.25mm to 0.4mm.
So if you’re making your own tool, you need to start by getting the right-sized needles. A good idea is to purchase Acupuncture needles at your local store or get some online on Amazon.
Next, insert your needles into a cork top and your WDT tool is ready to use!
If you have access to a 3D printer, you can also get a 3D-printed WDT device. Like with the DIY method, you will also need to get the rightly-sized acupuncture needles. Once you get your needles, download and 3D print the free files. Then insert your needles and screw the pieces together.

Weiss Distribution Technique
Making homemade coffee with espresso is particularly challenging, where everything from beverage size to water contact time is scaled down, making any unevenness stand out.
Unfortunately, we don’t have many options in terms of equipment when it comes to a homemade espresso. Even high-end products may not be ideal for home-friendly volumes. This is where WDT (aka Weiss Distribution Technique) comes into play.
WDT Tools help you ensure that some of the coffee is not being over-extracted or under-extracted, leading to bitter or acidic flavors. Using WDT, you can evenly distribute your coffee in the portafilter to compensate for those shortcomings and brew better espresso.
The stirring process distributes the grounds evenly throughout the filter basket. The needle allows you to do this by penetrating the bottom of the basket.
You need one other piece of equipment to avoid making a mess: a funnel that is placed inside the filter basket to contain your coffee grounds so they don’t fly out while stirring.
The best part is that you don’t have to make any significant adjustments to your coffee brewing method.
Once you are done de-clumping and distributing your coffee grounds, remove the funnel and proceed to brew and extract your espresso with your preferred brewing regimen.
