I don't know how they do it in VV, but usually, For sparkling wines they use a device called coravin, which seals the bottle hermetically and fills the excess space of the wine served with CO2, which it injects from a capsule. For white wines, the same system is used, with the difference that the wine is accessed with a needle, without uncorking the wine. It is the only way to be able to uncork and keep such exclusive wines in good condition.
