KNODOS Single Dose Coffee Bean Storage Tubes with Walnut Stand — One-Way Exhaust Valve

The KNODOS Single Dose Coffee Bean Storage Tubes with Walnut Stand include 12 glass tubes with one-way exhaust valve lids, 4 replacement tubes, a solid walnut display stand, and a stainless steel dosing funnel. The one-way valve lets CO2 escape from freshly roasted beans while blocking oxygen from entering — keeping beans fresher longer than standard airtight lids. Pre-portion your doses, store them sealed, and grab one tube each morning. Each tube holds 18–21g of whole beans depending on roast level.

One-Way Exhaust Valve

Freshly roasted coffee releases CO2 for days after roasting. A sealed container without a valve builds pressure and can push stale air back into the beans when opened. The one-way valve on each tube lid lets CO2 escape while blocking oxygen from entering. The beans stay fresh longer because they are not sitting in a pool of oxygen between roasting and brewing.

Single Dose Workflow

Weigh your beans once per batch. Fill each tube with one dose — typically 18g for a double shot. Seal the lids and place the tubes in the walnut stand. Each morning, grab one tube, pour the beans into your grinder, and grind. No scale needed, no bag to open and reseal, no beans left exposed to air in a hopper.

Stainless Steel Funnel

The included stainless steel funnel sits on top of each tube opening and guides beans in without spilling. Pour weighed beans through the funnel into the tube, remove the funnel, screw on the lid. Clean and fast.

Walnut Display Stand

A solid walnut block with 12 drilled slots that hold each tube upright. Keeps your counter organized and your doses visible — you can see how many are left at a glance. The walnut matches KNODOS walnut tampers, distributors, portafilters, and tamping stations.
