Coravin is the innovative wine preservation system that allows you to pour any wine by the glass without the need to pull the cork, keeping your wines fresh until you decide to have the next glass. By eliminating the risk of oxidisation, Coravin provides the freedom and flexibility to enjoy wine on your own terms. Pressurising bottles with argon gas to pour wine a glass at a time, Coravin Capsules are the power source of the Coravin System and a fundamental component of the Coravin technology. Argon capsules are not compatible with Coravin Sparkling.
