Decanter that '76 is "drink soon," rather than "drink now." The first and second growths will still have plenty of stuffing at this point. Some specifics:
The real question is how much you want to spend and if you want to buy retail or at auction.
Not too many options for 1976 Bordeaux on the auction front.
Best one around: Sotheby's NYC auction 4/18, lot 980, 12 blts of Lafite Rotschild 1976, lot estimates 1.5/2 K.
BTW, the Lafite is one of the best 76s, highly rated ( "The 1976 has turned out to be the best Lafite of the '70s. It is gorgeous to drink at present. Anticipated maturity: Now-2005. ", said the Guru )
A recent ( 3/28 ) NYC Christie's auction didn't have any 1976 Bordeaux, aka "Claret". Period.
An upcoming (4/3 & 4/4) NYC Zachy's auction shows one btl of the Lafite, 2 Vieux Chateau Certan, 1 Haut Brion, although in mixed lots, with stuff from other years making up the lots.
Back to the first option above: wine-searcher.com shows single bottle retail prices for the 76 Lafite in the 400 to 650 range, so the auction estimates ( which usually hold ) are not bad at all.
re: Brad Ballinger
1976 in Germany was a fantastic vintage. Lots of botrytis, and yes they are still alive if you choose the designations you mention Brad. Getting late for many auslesen though too.
Definitely agree to stick to rieslings, they last longer than the hybrids, generally, one reason for which is that they are what's planted to the best sites.
Not a fantastic vintage - Barsac/Sauternes, St Estephe/Julien or Pauillac are probably the way to go but be sure to check up on specific wines before buying as most of them will probably be past their best. I'd look out for these:
d'Yquem (get the cheque book out)
St Estephe/St Julien:
Pichon-Longueville Comtesse de Lalande
Haut Bages Liberal
Les Forts de Latour
Nothing outstanding, but if you pick the vintage it can be hard to find great wines!
