It would be misleading to, as youre aware, paint with excessively broad strokes as regards the quality and consequently (although not always causally) pricing of the 1st growths within specific vintages. For example, whilst the 45 was generally a great year for most of Bordeaux, Mouton Rothschild and Latour really shone, hence a bottle of 45 Lafite Rothschild can be picked up for £800 and a bottle of either Mouton Rothschild or Latour for around £2,500. So for out £45,000, we could conceivably get in at least one horizontal tasting of maybe Haut-Brion, Lafite Rothschild, Latour, Margaux, Mouton Rothschild, Petrus and dYquem (although being a Sauternes, dYquem is slightly anomalous vintage-wise compared to the other [red] wines). Maybe, even a horizontal of the 1900 or 1928 (lets push the boat out).
Oh dear, this theorizing is getting all out of hand.
Looking forward to seeing others choices.
