Hi,

I don't drink alchohol and know next to nothing about it, but some
recipes call for the addition of white or red wine, or sherry. I
understand that grocery store "cooking wine" is to be avoided, but my
question is this: doesn't wine go bad once it's opened? Do people who
cook with wine sacrifice a whole bottle to get the recipe's 1/4 cup or
2 tablespoons? Or do they plan to drink the rest the same day? Wine
lovers insist on a "three day rule" once the bottle has been opened . .
I understand that cooking wine can keep for a year or so . . .

Thanks!
