storage of open wine...

[Bucko]

Often a hotly debated subject. The best thing to do, obviously, is to drink the wine. Placing the remains in a half-bottle cuts down on air space and oxidation of the wine. Vacuvins do not work very well. Private Preserve provides a protective blanket of nitrogen over the wine, and seems to work best, especially if refrigerating. In any case, you should drink the the wine within 3-4 days for taste appeal. There are no health risks from leaving the wine in the fridge for longer periods that I know of - it will just deteriorate in taste.
