  • Introducing the pinnacle in coffee distribution! DUOMO The Eight brings competition level extraction with every shot of espresso. Using DUOMO The Eight is a very pleasurable experience. The high-quality aluminum body feels great in the hand and looks even better on your countertop. The Eight is very ergonomic, and can excel in a busy cafe or compliment a meditative, morning espresso routine. The action of the press is very satisfying, the spin is effortless and effective, and the base has a built in brush to keep the eight needles nice and tidy.

    DUOMO designed The Eight around the technique of the Weiss Distribution Technique (WDT). The Eight perfects the WDT and produces a more even, efficient and clean distribution (good-bye funnel and paper clip!). The design and placement of the eight needles allow for optimal performance. The end result is fluffy espresso that is evenly distributed throughout the entire basket. Shots pull more consistently and showcase the espresso in its truest form.

    Clumpy, poorly distributed espresso, meet your maker!

Money well spent

Tried this in the showroom, was really impressed by it, compared to other WDT tool, I’d rather have this. Consistent results and easy to use! You will know when you try it!

A wdt star is born

I was having hard time getting perfect shot out of my bottomless portafilter on my LMLM. I tried a DYI wdt but didn’t see a lot of improvement. Also tried the OCD distributor which helped me to get a steadier tamping technique but still regularly uneven extractions. Finally, I purchased the Duomo and then the magic happened. I was finally able to grind finer and constantly get an even and tasteful extraction. I was just about to upgrade my grinder, but now I feel completely satisfied. Do yourself a favor if your in the perfect espresso game and get yourself one of these beauties.

Perfect Shots

Must have tool in my workflow. Significantly reduce the chance of getting channeling in the puck, which also allows me to be able to grind finer for light roasts.

Robust and easy to use

The price is high, but if the budget allows then Duomo The Eight is the endgame WDT tool I would not hesitate to recommend. It is super easy to use, built like a tank but smooth as butter. The grinds come out fluffy and clump free. The shots are consistent, because the workflow with Duomo is predictable and error free. The tool is also adjustable so the needles can be adjusted up/down to fit the depth of any portafilter basket.

Idiot Proof

This tool completely simplifies the WDT process. It's consistent every time, makes the workflow fast and easy and it functions flawlessly. As others point out - the craftsmanship and materials along with the design are top notch. It looks cool and belongs sitting next to a Slayer and an EG-1. Worth every penny and I'm glad I own one.
