Oxygen, moisture and temperature swings are all enemies of coffee! Ordinary canisters allow oxygen inside with the contents, which can quickly degrade your beans. With Airscape's patented valve, air is forced out of the container before locking the lid in place. With The Roasterie on the front and our iconic DC-3 airplane on the back, this canister will look great in your kitchen while preserving your Roasterie coffee. Airscape holds up to 1lb of coffee.
