  • 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!

Game changer

I’m fanatical when it comes to perfect espresso at home, and have pulled over 15K shots. This is by far the best espresso tool I’ve ever used, clean and simple. Consistent, even distribution all the way to the bottom of the puck = consistent uniform extractions with zero channeling = consistently perfect espresso every time. Top quality material and design, and well worth it. I still use the BT wedge to cleanly level the puck afterwards, before tamping, but most distributor tools are actually surface groomers, not distribution tools. 5 stars all around.

Best wdt

No more mess when using naked.
No more mess when distributing.
Much cleaner taste. And no more channeling due to clumps.

A big improvement, even for experienced espresso nerds

This tool normalizes a great deal of variability in even the most rigorous, muscle-memory-driven WDT behaviours. I realized within the first few days of using it how sloppy I was with my prior methods, and sure enough my puck prep has increased commensurately. There's even an argument that you'll save money despite the cost, since your % of "good" drinks will increase, requiring fewer sink shots and less waste. YMMV on how long that takes though!

Overall I just love the quality and results of the tool, and when I emailed Jeff at Coffeez in Korea with questions and suggestions, he was responsive and forthcoming with his responses.

I Achieved Great Results Instantly

The flavour has improved so much compared to my old WDT routine. The shots have more body, and are less astringent or burnt. Visually, coffee seems to pour more evenly from the basket. Therefore, I'll definitely say it improved extraction! It is an extra step but a quick one. Here's my routine: Grind desired amount in my cup -> shake and use a puck rake to remove big clogs -> transfer in the pf basket -> give a small tap -> use the duomo -> tamp.

The tool in itself is beautiful. It has a very robust design too, and is very confortable to use and clean.

A few things I do not like though:
- The base seems a little cheap, and is not heavy enough. Therefore because there is a magnetic connection, most of the time when I grab my Duomo the base stick to it
- The needles seems too short. I'd like to go at the bottom of my 18g basket and that's around 24mm, but the tool do not go beyond 23mm (as the spec says)

(I found the height by pulling the Duomo and measuring the axis with a caliper)

Duomo Eight Distribution Tool

The Duomo distribution tool is the best distribution tool I have used in my 30 years of espresso extraction. When used with a good fit tamper it is a great tool for even distribution, no channelling, and great extraction. Highly recommended!
