Coravin capsules are 3 replacements for the Coravin system.
The Coravin capsules are two replacement pressurised bottles that provide argon gas for the Coravin system. This gas is necessary to maintain the internal pressure of the bottle to keep the properties of the wine, such as its aroma and flavour, intact.
The pressurised argon capsules are the power source of the Coravin system.
The Coravin system was created by Greg Lambert, an engineer from the Massachusetts Institute of Technology, when his wife became pregnant and stopped drinking wine. The passion of this engineer for good wines along with the need to avoid wasting the rest of the wine from bottles he uncorked and did not finish, led him to design a prototype that has revolutionised the world of wine. Since then, we are able to enjoy great wines without having to finish the entire bottle.
