New to Collecting Vintage Wines

[sharktanq]

Hello All,

Recently, my wife and I purchased several bottles of wine from Concannon Winery in Livermore, CA. In addition to our normal wine list, we purchased some vintage wines, a 1992 Reserve Zinfandel, a 1992 Reserve Petite Sirah, a 1992 Reserve Assemblage, and a 1985 Reserve Cabernet Sauvignon. I have been looking around for Vintage Charts that can help me decide how long I can keep them, or if I should drink them soon. I've seen mixed results from various charts, and am not sure which is the best to be consistant, and I've found nothing that charts the Petite Sirah. Can anyone give me some guidance on this?
