by coolerman on. The best temperature for storing all wines – reds, whites, champagnes, and ports – is around 55 degrees (F). For long-term storage – 6 months or more-you really want to stay around this temperature.For short-term storage, the temperature doesn’t matter as much.any casual wine drinkers are aware of the problems with heat in wine storage, and some may opt to store their wine in the kitchen fridge. However, this is not a good practice, for a number of reasons. First, the temperature is actually too cold, and if left there long-term, can actually “flatten” the taste of the wine.
