Jura, les vins jaunes

[GrandCru]

I am new to this web site and this is the first time I have used the message board. I am wondering if anyone knows if certain years of wine production for the juras are better than others. I have a 1992 Chateau-Chalon, vin jaune. I have done some research and although most sites say you can keep these wines for up to 50 years I would like to know if some years are better than others. I have actually never tasted a Jura and would like to do so; so I guess my real question is should I drink my '92 and buy a different/better year if I like it or should I hold the '92 and try drinking another year? Any thoughts?
