58mm/54mm Magnetic Dosing Ring – Clean, Precise, and Professional Espresso Brewing

Magnetic Dosing Ring – No More Coffee Waste and Mess on Your Counter

Are you tired of half of your expensive coffee ending up on the kitchen counter instead of in the basket? BloomVik’s magnetic dosing ring (dosing funnel) is the simple yet brilliant solution that transforms your dosing from a mess into a clean, professional routine. Avoid waste and gain full control over your coffee puck from start to finish.

Whether you grind directly into your portafilter or use WDT (Weiss Distribution Technique) to break up clumps, the strong magnetic base ensures the ring stays exactly where it should. This gives you the freedom to stir and distribute the coffee without fear of it spilling over the edge.

"A clean bar is a fast bar. With a dosing ring, you not only save money on wasted coffee; you also save time on the endless cleanup between your shots."

Why this dosing ring is indispensable:

• Strong Magnetic Base: Unlike cheap plastic funnels that slide around, our anodized aluminum ring locks firmly onto your portafilter. It stays put even if you shake the portafilter or work intensely with your WDT needles.
• Perfect for WDT: The extra height of the ring gives you space to stir all the way to the bottom of the basket and effectively break up clumps, which is key to avoiding channeling and achieving a balanced flavor.
• Workflow Optimization: You can grind directly from your grinder into the funnel. This ensures the coffee lands centered and fluffy, making it much easier to achieve an even tamp afterward.
• Anodized Aluminum: The material is lightweight, extremely durable, and static-resistant. This means coffee grounds don’t stick to the ring but fall neatly into the basket.
• Sleek Design: With its matte finish and the discreet Home Roast logo, it fits perfectly into the modern coffee corner next to your Slayer, Faema, Rocket, Sage, or La Marzocco.

Will it fit my machine?

We offer two precision sizes that cover almost all needs in 2026:

• 54 mm: The perfect match for Sage/Breville machines (such as Barista Express, Touch, Bambino, and Infuser).
• 58 mm: The standard for all professional machines and E61 groups (e.g., Rocket, Profitec, ECM, Lelit, Slayer, Faema).

FAQ – Frequently Asked Questions

Can I tamp while the ring is on? Most tampers sized 54/58 mm can go directly through the ring, but for best results, we recommend removing the ring after distribution (WDT) and giving the portafilter a light tap on the counter before tamping.

Do the magnets scratch my portafilter? No, the magnets are recessed and the material is softer than the stainless steel in your filter basket, so you can use it daily without worrying about scratches.

Why use magnets instead of just a funnel? Without magnets, the funnel can tip when you stir the coffee. This causes waste and frustration. The magnets give you the confidence needed to work quickly and precisely.
