Nitrogen Canisters for Wine Preservation
Nitrogen wine preservation systems like the Keeper use a blanket of nitrogen to displace oxygen inside your wine bottle, preventing the effect of oxidization on your wines. This requires a nitrogen canister, and when you run out of nitrogen you can no longer preserve your open bottles. Ensure that you are never without the ability to preserve your wine by purchasing extra nitrogen canisters. Each nitrogen canister preserves about 25 bottles of wine.
