And now we don’t have to open the bottle to drink its contents. Coravin is this wonderful new technology that uses a special needle to extract the wine. It also fills the space left with inert Argon gas, thus not exposing the wine to any oxygen and leaving it virtually the same as it was before being accessed. I have not had any personal long-term use with the Coravin system yet, but it comes highly recommended by wine professionals as a tool to pour yourself a glass of wine without opening the bottle. Sounds great to me!
