We earn from qualifying purchases, including as an Amazon Associate, from Prima Coffee, and from Flair Espresso. No brand-paid placements.

These tools keep grounds in the basket, sit on the puck, or replace a stock basket and spouted portafilter. Standalone dosing cups are not on this page; the funnels below do the job of catching grounds as you grind.

If you use a 54 mm Breville such as the Barista Express, start with the Normcore 54 mm funnel here, then see the Barista Express accessories page for a matching basket, screen, and bottomless portafilter.

How to choose

Start with size.

54 mm machines. Buy the Normcore 54 mm magnetic funnel. Use the Barista Express accessories page for a 54 mm basket, 53.3 mm screen, and 54 mm bottomless portafilter.
58 mm machines. Buy The Ring, then add a VST basket. Choose the Normcore Ultra-Slim screen or the Weber screen. Add the Breville 58 mm bottomless if your machine is a 58 mm Breville, or the La Marzocco bottomless if that is the portafilter your machine takes.

The Breville 58 mm bottomless portafilter is not for the Barista Express, Barista Pro, or Bambino.

FAQ

Do I need a dosing cup or a dosing funnel?

A funnel that sits on the portafilter is the piece we recommend. It keeps grounds in the basket while you grind or use a WDT tool.

Will The Ring fit a Barista Express?

No. The Ring is 58 mm. The Barista Express uses a 54 mm portafilter; use the Normcore 54 mm magnetic funnel instead.
