Description

MHW Magnetic Dosing Ring: 58mm Matte Black

MHW-3Bomber Magnetic Dosing Ring in Matte Black offers a clean, efficient solution for dosing espresso shots with minimal mess. Designed for 58mm, 53/54mm, and 51mm portafilters, this dosing ring attaches magnetically, blocks flyaway grinds, and evenly distributes coffee powder.

Clean Dosing, No More Mess

Engineered to address the common issue of spattering during dosing, the MHW-3Bomber Magnetic Dosing Ring securely locks onto your portafilter with 10 embedded magnetic beads. The flaring design expands the bottom diameter by up to 10% compared to traditional rings, promoting even distribution and eliminating clumps or overflow. Built from anodised aluminium alloy, the dosing ring is durable, corrosion-resistant, and easy to clean.

Questions & Answers

  • What is the benefit of a magnetic dosing ring?
    Magnetic dosing rings attach firmly to your portafilter, preventing coffee powder from flying out during grinding. They simplify dosing, reduce mess, and help improve consistency.
  • How do I choose the correct size for my portafilter?
    Match the dosing ring size to your portafilter basket diameter. Common options include 58mm, 53/54mm, and 51mm. Check your machine specs before purchasing.
  • Will the magnets damage my portafilter?
    No. The magnets are embedded and designed to hold the ring securely without scratching or damaging the portafilter surface.
  • Is it dishwasher safe?
    It is best to hand-wash the dosing ring with mild detergent and dry it immediately. Dishwashers may affect the anodised finish over time.
  • Can I use this with a dosing cup?
    Yes. The flared base and wider opening of the ring help channel grounds directly into dosing cups or portafilters without a mess.
