What it is

The Distro Coffee Labs Retention Bellows is a specialized accessory designed to address the small amount of coffee grounds that inevitably get trapped in the Niche Zero and Duo internal pathways. By applying a quick manual pump to the top of the hopper, this tool forces air through the burr chamber to eject trapped grinds. This simple mechanical addition helps maintain the integrity of single dosing by ensuring the weight of beans put in matches the output exactly. Constructed from thick, 100% food grade silicone, the bellows provides a tactile and durable solution that integrates seamlessly with the grinder's premium aesthetics. It eliminates the need for messy RDT (water spraying) or aggressive tapping, keeping your workspace cleaner. For home baristas who swap between different beans frequently, this accessory prevents old grounds from contaminating the flavor profile of the next brew.

Ravvy AI insight

While the Niche series is famous for low retention, static still traps up to 0.3g of coffee which can stale between uses. This bellows is a cost-effective alternative to expensive hopper replacements, offering a high-utility fix for a fraction of the price of premium wood-capped versions.

For the best results, wait until the motor has completely stopped spinning before pumping the bellows. A quick, firm tap provides better air velocity to dislodge stubborn grounds than a slow squeeze.

Ownership tips

care

Cleaning the Silicone

Wash the bellows with warm soapy water every few weeks to remove oils and coffee dust. Ensure it is completely dry before placing it back on the grinder to avoid moisture entering the burr chamber.

tip

Static Reduction

Combine the use of this bellows with the Ross Droplet Technique for the cleanest possible workflow. A tiny drop of water on the beans reduces static, making the bellows even more effective at clearing the chute.

Frequently asked questions

Does this require removing the original Niche lid?

Yes, this bellows is designed to sit directly on the hopper in place of or underneath the standard lid setup depending on your preference. It creates the necessary airtight seal to push air through the grind chamber.

Will this fit other grinder brands?

This specific model is sized precisely for the Niche Zero and Niche Duo. While it may fit other hoppers with similar diameters, it is not guaranteed to create an airtight seal on non-Niche products.

Is the silicone heat resistant?

While the bellows is made of high quality silicone, it is intended for use at room temperature on the grinder hopper. It should be kept away from direct heat sources like stovetops or espresso machine boilers.

Does it affect the grind quality?
