Rocket Dosing Funnel Magnetic Aluminum – for 58mm Portafilters
The grinder stops, the grounds still sit loose in the basket, and for a heartbeat it is open how much of it actually ends up where it belongs. A quiet click, the aluminum funnel sets itself magnetically on the rim of the portafilter, and the whole path from the burrs to the coffee bed is guided instead of left to chance.
That is how simple order can be in the morning.
What makes it special
Freshly ground coffee is light and electrostatically charged – some of it likes to find its own way while you fill the basket, drifting across the drip tray instead of straight into the portafilter. The funnel gathers exactly that scatter on its way to the coffee bed, so more of it lands where it belongs. A small foundation for everything that follows – distributing, tamping, the extraction we at CCC prefer to think of by weight ratio rather than time alone. Whether 1:2 is your measure or something else that tastes right to you is your call. Our take on it is one of many.
The magnet holds the funnel exactly where it belongs, without you needing to hold it in place while dosing – both hands free for the scale and for watching the grounds. Made of aluminum, it sits light in the hand and stays, shot after shot, what it was on day one.

Who it is for
For anyone working at home with a 58mm portafilter who wants less powder on the drip tray and more of it in the basket when dosing. No prior experience needed, no adjustment, no extra tool required – it sits, it holds, and makes filling easier, whether it is day one with your own machine or years into espresso. No experience level left out, no budget too small for a bit more tidiness at the machine.
Also worth a look
If you are pairing the funnel with a tamper, our Normcore Collection has the compact, precise option at a fair price, and our Weber Workshops Collection has the version for anyone who wants more heft in hand – both do the same job, just feel different. Weighing your grounds works much the same way: Normcore for anyone who wants something compact and reliable, or our Acaia Collection for anyone who also wants flow-rate display and app connectivity. And if you are still after the right machine to go with it, our Rocket Espresso Collection is worth a look, or use our coffee machine comparison tool when the choice feels wide open.
Frequently asked questions
Will the dosing funnel fit my portafilter?
Yes, it is made for 58mm portafilters and holds magnetically on the rim, without you needing to hold it in place.
How does the magnetic attachment work?
The funnel sets itself on the metal rim of the portafilter and stays there on its own until you lift it off after dosing.
What does a dosing funnel do for the espresso ritual?
It guides the grounds precisely into the basket, so less spills over the edge and the powder distributes more evenly – a small foundation for everything that follows in distributing and tamping.
Is the dosing funnel available in another color?
Yes, it is also available black coated – same function, same size, different look. Both versions fit 58mm portafilters.
Can I see the product before buying it?
Yes, you will find the dosing funnel in our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b). Buying online is the simplest way, with delivery throughout Switzerland and to Liechtenstein in 2–4 business days; if you would like to experience it live first, you are warmly welcome in the showroom.
Roastery tip
From the roastery, our favorite pairing for a cleanly dosed espresso is Cozy Chocolate or Nutty Delight – full-bodied, aromatic, dense, exactly what most people want for a good morning. If you are after maximum body with no acidity at all, you will find it in Very Nutty. And for anyone curious about a fruity experience: Wild Peach is a discovery on the side, lively and fruity – never the headline, always an option. That is our recommendation, one of many; whichever bean tastes right to you is the right one.
