As Jay said, the one unfortunate thing about this thread is that at least one person is taking the worst possible interpretation of a buying strategy - buy 2005s to drink now. These wines are very tight right now (and not just the grand crus) and it is the exception, not the majority, that will drink well right now. The wines will be great (I think) but I would not drink them now.
I expect a number of people to ignore the last paragraph so that I am expecting a rash of threads on how overrated Burgundy is and how it is a minefield because even the great 2005s don’t taste very good.
The best advice given above is to focus on producer over vintage. I am not wild about either the 2003 or 2004 vintages in general, but that does not matter if you buy Mugneret-Gibourg, who made beautiful wines in both years.
For drinking now, my guess is that the best of the more recent vintages are 1998 and 2000. As these are not considered great vintages, you can often find dynamite wines from these vintages at really nice prices. Two other vintages that can be found at pretty good prices right now are 1996 and 2001. These vintages ultimately will be a step up from 1998 and 2000 and are real buys. But for drinking now, nothing beats the 2000s, unless you can find old wines.
There has been a lot of debate between 2001 and 2002 as to which is the better vintage. This does not matter because they are both excellent vintages, with 2001 producing more complex wines and 2002 wines with more fruit, in general.
The great recent vintages are 1993, 1999 and 2005.
My least favorite recent vintages have been 1997, 2003 and 2004.
I think 2006 will turn out to be somewhat similar to 2001, so if you see them at a good price, buy them. I think 2007 is not as good as 2006, but the wines seem clean and fresh and probably are better than 1997, 2003 and 2004.
I have only had a couple of 2008s so far and like them. They could be similar to 2001 and 2006. I will get to taste a whole bunch more in February in NY at the the Paulee. Prices sure seem good. I have had no 2009s and cannot comment. But they will have to be really good to justify some of the price increases I have seen over the 2008s.
Again, producer, producer, producer. There are tons of excellent producers so you don’t have to go for the hot overpriced ones. Some of my favorites include Jadot, Drouhin, Bouchard, Bachelet, Fourrier, Rossignol-Trapet, Barthod, Mugneret-Gibourg, Michel Gaunoux, D’Angerville, Lafarge, Clos des Lambrays, Chandon des Briailles, Jouan, Chevillon, Cecille Tremblay, Pierre Morey, Pavelot, Rousseau, Roumier, Mugnier, and Faiveley. [I leave out Truchot only because he does not, in general, make wines anymore.]
Now, go out, buy those 2005s, drink them now and tell us how overrated Burgundy is. Convince people so that they will dump them and I can get good prices.
