Use a Coravin – The main purpose of this unique device is to avoid uncorking the bottle at any point. The Coravin tops the bottle with argon gas by using a needle, allowing you to pour the amount that you wish and remove the needle so the cork will seal naturally, limiting the wine’s oxygen exposure. It can be a bit pricey, but it is well worth it if you have vintages you want to enjoy slowly. This device is used frequently in restaurants and is making its way to wine lovers’ own homes.
