Tired of coffee grounds scattered across your counter every time you dose? The magnetic espresso dosing funnel solves that frustration in seconds. Engineered from aerospace-grade aluminum with a powerful embedded magnet array, this V3 funnel snaps onto your portafilter instantly and keeps every milligram of coffee exactly where it belongs. Whether you grind directly into your basket or transfer from a dosing cup, the wide-mouth design catches everything cleanly. Your workflow gets faster, your station stays spotless, and your dose stays consistent shot after shot. Why Home Baristas Love This Coffee Dosing Funnel Inconsistent dosing is the silent killer of great espresso. Lose even half a gram of grounds to scatter and your ratio shifts, your extraction suffers, and that dialed-in recipe falls apart. This portafilter dosing ring uses 360-degree magnetic distribution to lock firmly from any angle, giving you a stable platform for grinding, stirring, and distributing without second-guessing your attachment. The anti-static aluminum surface prevents grounds from clinging to the funnel walls, so every particle drops into the basket. No tapping, no fuss, no wasted coffee. Precision Aluminum Build for Daily Espresso Prep Unlike flimsy plastic alternatives, this funnel is machined from aerospace-grade aluminum that resists corrosion, wipes clean in seconds, and feels genuinely premium in hand. The external locking structure provides a snug, rattle-free fit during simultaneous grinding and WDT work, so you can focus on technique instead of fighting your tools. Available in three sizes to fit 51mm, 54mm, and 58mm portafilters, it covers virtually every popular home espresso machine on the market.
