Profitec Single Dose Bellow – less retention in the grinder
A few short presses on the soft dome, a quiet hiss, and the last of the ground coffee drops down.
Why retention ends up in your cup
Between the grinding chamber and the exit chute there are gaps, and with every grind a little is left behind in them. Next time, this residue comes out along with the rest, only by then it's no longer fresh. Coffee brings more than eight hundred aromatic compounds with it, and of all of them it's the most volatile ones, the ones that make up the aroma, that change fastest in the air.
That's exactly where the Bellow comes in. After grinding, you press the dome a few times, air is pushed through the grinder, and the residue reliably comes loose. What you weighed in is what arrives at the bottom, and the next dose starts without yesterday's baggage. Profitec fits the same Bellow to the TWIST SD54 and also offers it separately, for use with the complete Profitec grinder range.
It's the small, unspectacular kind of improvement you only notice once you've had it for a week. No shot can be replicated anyway, because the bean, the humidity and the person change every day, and that's how it should be. The Bellow simply takes one variable out. Our opinion is one of many.

Who it's made for
For anyone who weighs out their beans dose by dose and wants that dose to arrive in the portafilter in full. For anyone who switches between two beans and doesn't want one mixing into the other. And for anyone with a Profitec grinder who'd like to add single-dose operation without replacing the grinder.
No budget is merely a starting point, and no setup is too small for clean grinding. If you're thinking about a grinder anyway, take a look at our single dose espresso grinders, where the whole range sits side by side.
What goes well with it
Single dosing starts at the scale. For anyone who wants to weigh compactly, precisely and reliably: the scales and dosing cups from our Normcore collection. If you want an app, Bluetooth and a flow-rate display, you'll find that in the Acaia collection, and if you want more from dosing cups and tools, in the Weber Workshops collection.
And the grinder itself is the bigger decision. For anyone who wants to grind affordably and precisely, the Varia VS3, the Comandante C40 and Timemore's hand grinders are strong answers. If you want more, you'll end up with the Varia VS6, the Weber EG-1 or the Option-O Lagom. They're all in our coffee grinders, and burr sets are like car engines: subjective, there's no single best.
Frequently asked questions
Which grinders does the Single Dose Bellow fit?
Profitec lists it as a separately available accessory that can be used with the complete Profitec grinder range. It comes fitted on the TWIST SD54. If you're unsure whether it fits your model, send us your grinder's item number and we'll check before you order.
What does the Bellow actually do?
During grinding, small amounts of ground coffee get stuck between the grinding chamber and the exit chute. After grinding, the Bellow pushes air through the grinder and loosens this residue. This lowers retention, and what ends up in your portafilter is the amount you put in.
Will I notice it in the cup?
Coffee brings more than eight hundred aromatic compounds with it, and the most volatile ones change fastest. Grounds left behind from the day before carry some of exactly that into your next shot. Whether you taste it depends on you, the bean and the day. Our opinion is one of many.
Do I need it if I don't grind single dose?
Not necessarily. If you work with a full bean hopper, you grind the rest of the previous dose through anyway. The Bellow becomes interesting as soon as you weigh out your beans and put each dose into the grinder individually.
Can I see the product before buying?
Yes. In our showrooms in Bern at Gerberngasse 44 and in Zurich at Hagenholzstrasse 50b, you can see it in person, right on a grinder.

From our coffee roastery
As a coffee roastery, we see every day how differently the same bean can taste. Cozy Chocolate and Nutty Delight are what we recommend to most people: round, sweet, dense, with chocolate and caramel. Very Nutty is the choice for maximum body without acidity.
And as a discovery now and then: Wild Peach, light roasted and fruity. That's our recommendation, one of many. There's no bean that doesn't work here.
