I'm not much of a wine drinker. I've had a bottle of chardonnay in my cabinet for about 8 years (1987 William Hill) standing upright. I'm attending a Shakespeare in the Park festival tomorrow and would like to impress my date but don't want to open a bad bottle of wine. Should I be concerned about the contents? Should I get another wine? Any help is appreciated.
