I bought some La Tache 1966 in Chicago sometime around 1970. I forget what it cost then, but it was less than you have to pay now for a just fairly good California Cabernet Sauvignon. It has been stored properly, and after opening this bottle, only one remains. I am saving that one for a tasting with my one bottle of 1966 Romanee-Conti sometime in the future.
Of course it is fully mature, but I believe it might hold fairly well a few more years. The color is not extremely deep as is "improved" Burgundy from the 60s era. It is a nice, fairly pale ruby with a bit of age showing around the rim. This wine is all about complexity and balence. There are many layers of floral, earty, and fruity components that fade in and out. At one moment it reminds you of one thing, then it reminds you of something else. You can find hints of many fruits, mixed spices, truffles, beets, etc. without having to try very hard to find them. There is enough acid, and the tannins now are light and medium. It went very well with roast beef filet(with ends removed) stuffed with a mushroom mixture - sort of like a Beef Wellington inverted so the stuffing is inside and without pastry. It was served with classic sauce Perigueux made with a good Sercil Madeira and a generous amount of fresh winter black truffles.
