Old Wines

[Screaming Mimi]

Hello! - I use wine bottles, both empty and full, as home decor and I received some old wines as a gift and I have never heard of them - I like to know about my wines and whether I should pop the cork and enjoy, or set them up to look pretty. I was hoping someone here could tell me smething about them. Here goes:

1990 Cypress Cove White Zinfandel California Coastal Select

The Christian Brothers Port 1980 - The label on this bottle also says that this unique wine was released on July 1,1985 in celebration of Brother Timothy's fifty years in the Napa Valley.

The Christian Brothers Select California Tokay

1990 Robert Pecota Samay Beaujolais Napa Valley

Baron Philippe de Rothschilde - Cadet Rose Bordeaux Rose (note that this is not a Mouton Cadet)

Any and all input is very welcome!
