Is my wine still good?

[tomas003]

Hi,

I have three bottles of wine that I was given a few years back. I would truly appreciate it if anyone could tell me if they are still good or if I should get rid of them. I store them on a shelf in my apartment. Here are the years and names:

1) 1996 - Varichon Et Clerc (Blanc de Blanc Brut).
2) 1997 - Erben Kabinett (Franz Wilh. Langguth Rheinhessen).
3) 1996 - Beringer (Napa Valley Sauvignon Blanc).

Thanks!
