What's in a year?

[G.Laurenceau]

I know when buying a bottle of wine one should care as to what year is on the bottle. What I don't know is which year one should look for on that bottle.

Going back only 10 years(1990-2000), which years are considered to be better years?

I tend to drink "Simi Rose of Cabernet" or a White Zinfandel...if it matters!
