Wine's age?

[txkajun]

Okay, I am scared to frustrate the mentors with ridiculous questions, but here goes:

IK advised that I try a Beaujolais, and suggested the BN 2001 only through the end of the month. IK then advised on other beaujolais. How do I know what vintage is ok, what is past drinking, and what is going to be awesome when I am actually in the store trying not to look too stupid?
