Not very long.

An open bottle not more then 2 nights. A closed bottle can last almost a year if we're saving it for something. I do have 2 bottles of 2000 Trius Grand Red in my parent's cellar that are to be opened next year.

Generally, a bottle is finished by the end of the night.

Directly proportionate to the frequency I have guests. If I were never to have guests, indefinitely, as I hate wine.

I've had 3 bottles since this last summer.

But my wine drinking was curtailed by my hospital stay in September and medication that keeps me from drinking alcohol.

I don't think any of us would drink it, so it would last until someone visited who would.

red......months
white....about an hour
