For under $100 a bottle you have literally hundreds of options for good Burgundy. What would you like to accomplish? My favorite white Burgundies are Puligny-Montrachet (whose 1er Crus can all be had for under $100) and offer what is IMO, the very best mix of intense fruit and bone-crushing minerality. Chablis is considered the fillet of terroir-driven white Burgs (again, MOST can be bought for under $100). Even Meursault, the most generous white Burg, can be very site-expressive. For Grand Cru, the under $100 can be hard to come by, but you might be able to find a dusty and forgotten Batard-Montrachet or Chevalier-Montrachet (which I often prefer to the former for its relative clarity and tension) hiding on someone’s shelf. Don't overlook TOP Macon producers either. There are certainly gems to be found -sometimes for a song. Red Burgundy is equally (and VERY OFTEN MORE) affordable. If GREAT white Burgundy is harder to make, GREAT red burgundy is more sensitive to vintage. The differences in village (and producer) are not as subtle. Generalizations aren't as possible in Burgundy as in Bordeaux, but each village has defining characteristics. If you only bring one red wine, it should be from Vosne-Romanee. There is no other village which capitalizes so emphatically the tight-rope dance of elegance and intensity that Burgundy has to offer. Nuits-Saint-Georges are often brambly and assertive. Chambolle-Musigny is certainly the most stunningly beautiful of Burgundies reds (and delicate and plush), and Volnay is the sleekest and most daring. Gevrey-Chambertin is often very muscular and puglelistic. These are some of my favorites, although there are dozens of other villages, each with profound differences in terroir. However, unlike the rest of the wine world, when buying Burgundy, the priorities are: Domaine, Vintage, AOC-in that order. Some of my favorites are:
Chablis: Dauvissat (Vincent), Raveneau, Fevre.
Puligny: Louis Carillon, Etienne Sauzet
Meursault: Patrick Javillier, Matrot
Marsannay: Bruno Clair
Vosne: DRC, Mongeard-Mugneret, Jayer-Gilles
Pouilly-Fuisse:Barraud, Eric Forest
NSG: Gouges, Bocquenet, Liger-Belair
, the only real way to explore the wines of Burgundy is to start popping corks. You'll NEVER go back to California Pinot Noir AGAIN!
