Also, remember that when people talk about serving red wine at room temp., the room temp. that is supposed to be taken into account is the French Countryside and not Florida or Los Angeles.
Red Wine should be served between 55-60 degrees F.
White Wine can be chilled in the refrigerator, then left out at room temp. until service. White wine should be served between 45-50 degrees F. When it's too cold (38-40 degrees) which is right out of the fridge or ice bath, the flavors will be muted because of the cold. Once it warms up a bit, the wine will open up and you'll be able to taste the flavor range.
