Single dosing on a Conti grinder

Conti’s grinders are built for outlet use — espresso bars, hotels and catering, where a machine is loaded with beans and expected to keep up. The CG100, for example, runs 64 mm flat burrs behind a 1.2 kg hopper at around 1380 rpm.

If you have a different model in the range, check its own documentation for burr size and hopper capacity — we have only quoted the figures we can source, and we are not going to guess at yours.

What this hopper does

It replaces the bulk bean hopper with one sized for a single dose. You weigh the beans you want, grind them, then press the silicone bellows so the air pushes grounds still sitting in the burr chamber and chute out into your portafilter.

The result is that you can switch coffees without emptying a hopper, stop leaving beans to stale between sessions, and reduce how much of the last dose turns up in the next one. If your Conti has moved from a commercial setting into a home or roastery bench, that is usually the gap worth closing.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
