Need Help With Some Gifted Wine

[The Poet]

My first thought was that all the white wines are all at least a decade old. Though red wines are generally considered to improve with age, the same is not necessarily true of whites. If the whites were stored in the proper environment, they could be better than they were "fresh", but if not they may have turned to vinegar.

As the nice Darrell said, there's one way to find out.
