What's your favorite "reserve" wine?

Earlier this month, several LA Winos blind-tasted the 2005 Ferrari-Carano Zinfandel against its more accomplished sibling, the 2005 Ferrari-Carano "Reserve" Zinfandel. As we discovered in our tasting, that one little word -- "reserve" -- made quite a difference.

In Europe, wines must meet certain qualifications to be labeled "reserve." In America, it's basically left to the discretion of the winemaker. Some producers, though, are using it in the way it was intended: to designate a wine of higher quality. Often this determination is based on prime vineyard location for a particular plot of grapes. Or maybe the wine is aged longer, or given some other kind of special treatment.

What's your favorite wine with the word "reserve" on the label? Is there a non-reserve version of the same wine? (Sometimes you won't be able to find a "non-reserve" version. I'm a huge fan of the 2004 Marques de Riscal "Reserva" Rioja, which I think is a steal at $14, but I've never seen a non-reserva version... maybe it doesn't get exported from Spain, I don't know).

And how about this: have you ever found a wine where the "reserve" is actually less impressive than the non-reserve? Share your successes and failures in the reserve world.....
