MHW-3BOMBER Magnetic Dosing Ring Yu Series 58.35 mm – no more coffee next to the basket
Magnetic dosing ring from the Yu series for 58 mm portafilters: 36 magnets, stainless steel and silicone. Buy in Switzerland, see it live in Bern and Zurich.
You have the portafilter ready, put the Yu ring on, and you can feel it pull itself onto the rim. The grounds trickle into the wide opening instead of onto the counter and drip tray. Even if you stir afterwards, the coffee stays where it belongs.
Features
Wide opening
The ring increases the catching area and the height above the basket. The ground coffee falls evenly into the basket instead of scattering onto the counter.
Holds on the outside of the portafilter
The ring sits on the outer rim of the portafilter and takes up no space in the basket. According to the manufacturer, its bottom diameter is 60 mm, compared with 55 mm for conventional dosing rings. This means no step is left between basket and ground coffee after dosing. It is held by 36 evenly spaced, hidden magnets that position it quickly and precisely.
Non-slip silicone ring
On the outside, the ring has a black silicone band. According to the manufacturer it is non-slip, wear-resistant and odourless, gives a secure grip in the hand and protects the ring.
SUS304 stainless steel
The body is made of SUS304 stainless steel, which does not rust. The ring is intended exclusively for 58 mm portafilters.
Will it hold on your portafilter?
The ring is made for 58 mm portafilters. Magnets only hold on a magnetic rim. If you are unsure, briefly hold an ordinary magnet to the rim of your portafilter: if it sticks, the ring will hold too.
Part of the Yu series
The ring is part of the Yu series from MHW-3BOMBER, which also includes the Cyclone Needle Distributor and the Yu Impact Tamper.
Cleaning
In our experience it is enough to knock out the ring briefly after use and wipe it with a damp cloth now and then. Then let it dry well.

For you if you grind straight into the portafilter and the grounds have been landing next to the basket. For everyone who stirs before tamping and does not want to push anything over the rim. And for home coffee bars where stainless steel and black already set the tone. Whether you need a dosing ring is up to you. Our opinion is one of many, and in the advice tool you will find the right setup around your portafilter.

Frequently asked questions

How do I clean the ring?

How quickly will the dosing ring be delivered?
Delivery takes 2–5 working days, throughout Switzerland and to Liechtenstein. Click and Collect is available in Bern and Zurich.
Can I see the ring before buying?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. It is best to ask us briefly beforehand whether the ring is on site.
Tip from the roastery: When grinding straight into the portafilter, the coffee piles up in the middle. In our experience it is worth distributing first with the ring still attached and only then removing it: that way nothing falls over the edge when you lift it off, and your dose stays exact. For dense, full-bodied espresso we recommend Cozy Chocolate with its chocolatey profile and Nutty Delight, our nutty blend from Brazil and India. If you are looking for maximum body without acidity, go for Very Nutty. And if you want to discover something fruity now and then, you will find it in Wild Peach. More coffees are under coffee beans. That is our recommendation, one of many.
