What is the shelf life for (unopened) Pino Grigio? I recently came across a bottle of Pino Grigio that's a few years old (label says 2012, and that's probably when it was bought).  We usually only break out a bottle of wine for guests or a special occasion -- exactly the wrong time to find out that it's way past its use-by date.  We're usually more prompt in our consumption; this was an oversight.

I have the impression that whites are more fragile than reds in this regard, and that less-dry wines are more fragile than drier ones.  (Please correct any misunderstandings.)  How likely is it that I could serve this wine to people I like?  More generally, how long is too long?

The wine has been stored at room temperature in a room that isn't too hot (but isn't a cellar either), away from light.
It’s tough to generalize, but most crisp whites have a best-before date of roughly two years from the vintage date on the label.
