# Magnetic Dosing Ring for Espresso 51/53/58mm - Anti-Static Coffee Funnel # Magnetic Anti-Static Espresso Dosing Ring 51/54/58mm – No More Grounds Flyoff Static electricity in espresso grinders is one of the most frustrating problems in home espresso. Ground coffee builds up electrostatic charge during the grinding process, and when it exits the burr chamber, those charged particles repel each other — and cling to any surface they land on, including the inside of your portafilter, the counter, your clothes, and the outside of the basket. The result: wasted grounds, messy countertops, and inconsistent doses. The **Magnetic Anti-Static Espresso Dosing Ring** addresses this directly, using a combination of magnetic attachment and an anti-static design to keep grounds where they belong: in the basket. ## How the Anti-Static Dosing Ring Works The ring sits magnetically on top of the portafilter basket, creating an elevated wall that catches ground coffee before it can scatter outward. The anti-static properties reduce the electrostatic charge on incoming grounds, making them less likely to repel each other and scatter. The magnetic attachment means the ring stays put during grinding without needing to hold it — freeing both hands. ## Key Features ### Magnetic Attachment Embedded magnets secure the ring to the portafilter basket rim. Place it once — it stays. Remove it with a slight tilt — it releases cleanly. No press-fitting, no alignment frustration. Works with standard 51mm, 54mm, and 58mm stainless steel basket rims. ### Anti-Static Design The ring material and construction are optimized to reduce charge accumulation. Ground particles drop more uniformly into the basket rather than flying outward. This is especially effective with single-dose grinders where static build-up is most intense due to small batch sizes. ### Raised Wall for Catch Zone The elevated ring wall acts as a containment boundary. Even if some grounds fly slightly upward after exiting the grinder, the wall intercepts them and directs them back into the basket. Nothing escapes to the counter. ### Compatible: 51mm / 54mm / 58mm Three sizes cover the full range of home espresso portafilters: DeLonghi Dedica (51mm), Breville Barista Express (54mm), and standard prosumer machines (58mm). Select the diameter matching your basket. ## Dosing Ring in Your Workflow 1. Attach the dosing ring magnetically to your portafilter basket rim 2. Grind directly into the portafilter through the open ring top 3. Weigh if needed (scale under portafilter) 4. Use WDT tool through the ring opening to distribute grounds 5. Remove ring by tilting — tap lightly over basket to drop any clinging grounds 6. Tamp and pull shot as normal ## Dosing Ring vs. Dosing Cup: Which to Choose? Scenario Use Dosing Ring Use Dosing Cup Grind directly into portafilter ✅ Ideal — Pre-weigh before transfer — ✅ Ideal Static flyoff is main problem ✅ Ideal Partial help Aroma preservation — ✅ Inverted design traps aromatics Minimal workflow steps ✅ Simpler One extra step (transfer) ## Compatible Machines DeLonghi Dedica (51mm), Breville Barista Express (54mm), Breville Barista Pro (54mm), La Marzocco Linea Mini (58mm), Rancilio Silvia (58mm), ECM Classika (58mm), Gaggia Classic (58mm), and most 58mm prosumer portafilter baskets. ## Frequently Asked Questions ### Will the magnets affect my espresso machine? The magnets are small and localized to the ring rim area. They don't generate fields strong enough to affect machine electronics or magnetize nearby metal components. Safe for use with all standard espresso machines. ### Does the ring work if my basket isn't perfectly flat on top? The magnetic seal requires a reasonably flat, smooth stainless rim to attach properly. Most standard IMS, VST, and OEM baskets work well. Heavily ridged or textured basket rims may reduce magnetic contact. ### Can I use the dosing ring with a WDT tool? Yes — the ring opening is sized to allow WDT needle tools to enter and work freely inside the basket. Distribute after grinding, then remove the ring before tamping. ## What's in the Box - Magnetic Anti-Static Espresso Dosing Ring × 1 (choose 51mm / 54mm / 58mm) _Eliminate grounds scatter for good.
