>>>I'll put it in the fridge
. . but hopefully you'll remember to take it OUT of the fridge at least an hour before serving it! Domestic refrigerators (at around 4C) are far too cold to chill wine, which (in the case of most whites and a few reds, such as Beaujolais Noveau) need to be served around 10C to 12C. Wines served straight from the fridge lose much of their flavour. (A decent Chardonnay, for example, should be packed with loads of flavour but most people only ever seem to taste very little of it, simply because they over-chill their wine).
