MATOW Stainless Steel Mini WDT Espresso Distribution Tool

I bought a bottomless portafilter recently and I had significant channeling. I had no idea what I was doing wrong, but my AI suggested that my "grounds were clumping". The idea seemed absurd but it ended up being right. It also said that many WDT tools can scratch the basket and specifically recommended this one. Well, it works. I stir my grounds in the grinder hopper and then add them to the portafilter and I've been routinely pulling single channel and double channel shots. This little $6 tool solved my espresso issues. Get it. It's such a small investment for such an improvement in extraction.

This is a good WDT mixer for espresso. But it's an amazing WDT tool for on-demand grinders. If you are mixing in the tamper, this tool has some loops that might be worth clipping off. But that's not my use case- I'm using a fairly large on-demand grinder. It's close to perfect- if I spent an order of magnitude more on the grinder maybe it would be! So instead, I use this $16 tool to make it perfect. Here's how it works: as grinds come out of the chute into your funnel, hold the wdt tool in the path. This breaks the clumps on the way down, and you don't actually need to do other puck prep in my experience. I've had stunning results with this technique- you can check out my video to see what it looks like in practice. To sum up, if you need an ultra fine wdt tool, keep looking. But if you grind on demand, this is a really valuable addition to your kit at a great price point. The materials are perfect, of course. It's just a matter of the exact use.

didn't like those little loops - cut them off Otherwise stir it around in the grounds and it does a good job of breaking up clumps. Seems to be very well made.

A simple and well-made tool. The stirrer breaks up the coffee ground clumps to reduce channeling. It's better than using a paper clip or a toothpick. I get more consistent and better espresso shots using this tool. It is well worth its price.

The fact that you're looking at this product means you probably are trying to find a WDT tool to distribute coffee grounds for more even espresso extraction. You're on the right track. However, you don't want this tool, because the loops at the ends pull clumps of bean around, creating the potential for water channeling anywhere there is a weakness in the puck dredged by the loops. You want something much smaller for WDT or raking. Jam some toothpicks into the end of a cork, and that will be better. Even better, get a tool with even finer needles (0.3mm 0.4mm?) because they will pass through the grounds and distribute them without displacing and dredging out channels.

Very good. Will get the job done. Great if you cut off the loops. Made in China

Nice Stainless steel wdt. Very sturdy and works well. Not cheaply made like the aluminum handle ones.

This is surprisingly well-made for the price, and beats any homemade WDT tool. The handle is thick and weighty, and the tips don't scratch the basket at all but still let you get into the edges to help reduce channeling. I haven't had any trouble with grinds getting stuck in the loops, either.

Ich benutze den Rührer um das Kaffeepulver im Siebträger gut zu verteilen bevor ich es mit dem Tamper anpresse. Funktioniert wirklich sehr gut und die Extraktion ist schön gleichmäßig. Ich empfehle dazu aber unbedingt einen Trichteraufsatz für den Siebträger, damit nichts daneben geht.

Lookong forward to uping my coffee game with these items. Am very impressed with the quality and weight of item.

I've seen dozens of these tools online but this is the only one I've seen so far that doesn't look like they just stuck pins into a piece of cork and painted it. This is made for the task. Has a nice bit of heft, textured handle and rounded ends so you don't scratch your portafilter. Oh, and very reasonable price.

El producto es bueno sin embargo son muy gruesos los filamentos por lo que es muy complicado agitar el café para deshacer los grumos

I've used everything from the humble paperclip right up to an expensive aluminium coffee flask shaker thing and this has been by far the best. The closest thing in design I've used was a small whisk that I cut and bent the cut ends of the metal into hooks. It should have been as good, but it was awful. Somehow this does what I couldn't get the whisk to do. Used in conjunction with a XUNADA 58mm Espresso Dosing Funnel to prevent grinds escaping and together they do a great job.
