Frequently Asked Questions

Q: What espresso machine sizes is this magnetic coffee dosing ring compatible with?

A: This coffee dosing ring is available in three standard sizes — 51mm, 53mm, and 58mm — making it compatible with the majority of home and prosumer espresso machines on the market. Simply check the diameter of your portafilter basket and choose the corresponding ring size.

Q: How does the magnetic coffee powder ring attach to the portafilter?

A: The ring features built-in embedded magnets that allow it to attach directly to your metal portafilter basket without any tools, screws, or adhesives. It snaps on and off quickly, making it easy to dose, distribute, and tamp without any hassle.

Q: Will the anti-splash dosing ring actually prevent coffee grounds from spilling?

A: Yes! The raised, high-wall design of the ring creates a collar around the portafilter basket that catches stray coffee grounds during grinding and distribution. This keeps your countertop clean and ensures more coffee ends up in your puck — not on your workspace.

Q: Is the coffee dosing ring durable enough for daily use?

A: Absolutely. The ring is made from high-quality aluminum alloy, which is both lightweight and resistant to daily wear, moisture, and heat. It's designed for long-term use by regular coffee drinkers and home baristas alike.
