Dear Dr. Vinny,
If I open a bottle of good Port wine and don't finish it, how long will the remainder last before its quality diminishes? How should I store it?
—Tom B., West Bloomfield, Mich.
Tick, tock, tick, tock. There is no single moment when an opened bottle of wine goes from being really fabulous to really awful, but deterioration is inevitable. Do your best to minimize the amount of oxygen the leftover wine is exposed to—you might consider transferring it to a smaller bottle, even if it's just a plastic water bottle with a twist-off cap. In any case, try to finish it within a week.
