A question on A few wines I aquired.

[P.Gonzalez]

Hi I am new to the wine thing and attempting to collect wines. Today I was going through my grandma's house and found some vintage wines, but I don't know if their any good. The wines I have are: Pouilley-Fuisse 1986, a Chardonney I believe; Bianco Vergine Valdichiana 1990, a white wine; Sutter Home fre, 1992 a chardonney; and Charles Krups 1987, a white zinfandel. If any one can offer any advice I will appreciate it.
