Grinding straight into a 54mm Breville portafilter often means coffee on the counter, especially once you start dosing 18g or more, or stirring the grounds with a WDT tool. A dosing funnel or dosing cup is a cheap fix, and it’s one of the accessories owners mention most often after their first upgrade.
This guide covers which type to choose and the best options for Breville’s 54mm machines, compared on manufacturer specifications and owner feedback. We haven’t tested these ourselves.

Dosing funnel or dosing cup?
- A dosing funnel sits on top of the portafilter. You grind into it, stir with a WDT tool if you use one, then lift it off and tamp. It’s the simplest upgrade.
- A dosing cup replaces the portafilter under the grinder. You grind into the cup, shake or stir, then flip it onto the portafilter. It’s handy with grinders that don’t have a portafilter holder, and it lets you weigh the dose on a scale before it goes in the basket.
Most Breville owners start with a funnel. Choose a cup if you use a hand grinder or a separate grinder without a portafilter fork.
An important fit warning for Barista Express owners
Normcore warns that its 54mm funnel can’t be used while the portafilter sits in the Barista Express’s built-in grinder cradle, because the cradle sits on top of the portafilter. You can still use it if you dose with a separate grinder, or hold the portafilter by hand. If you grind on a Barista Express, check the clearance of any funnel before buying, or use a dosing cup instead.

The best dosing funnels and cups
Best magnetic funnel
Normcore 54mm Magnetic Dosing Funnel V2

- 8 neodymium magnets
- 18mm tall, 84mm outer diameter, 44g
What’s good
- Magnets hold it firmly in place
- Short profile works well with WDT tools
- Knurled edge makes it easy to lift off
Watch out for

- Hand wash only
- Costs more than basic funnels

Frequently asked questions
Do I need a dosing funnel for a Breville?
Not strictly, but it stops grounds spilling, especially at 18g and above or when you stir with a WDT tool. It’s one of the cheapest upgrades that makes your routine cleaner.
Will a 54mm dosing funnel fit my Bambino Plus?
Funnels sized for Breville’s 54mm portafilters are made for the Bambino and Bambino Plus. Check the product listing for your model before you buy.
Can I use a dosing funnel with the Barista Express grinder?
Normcore says its 54mm funnel can’t be used while the portafilter is in the Barista Express’s built-in cradle. Check any funnel’s clearance, or use a dosing cup instead.
Funnel or cup: which is better?
A funnel is simpler if you grind into the portafilter. A cup is better with hand grinders or grinders without a portafilter holder, and it lets you weigh your dose first.
