Depends on the wine, storage conditions and whether you liked ages champagne or not.New to this wine, champagne, liquor threads. How long can a bottle of champagne be stored? I read that it's best to store it horizontally and stable temperature - would 18-20 degrees be fine?
Horizontally for sure. Ideal is probably cooler. More like 12C - 14C, but 18-20 would be ok for shorter to medium term. More important is constant temperature.
