I have had an unopened wooden case of Mouton-Rothschild 1975 stored under near ideal conditions without moving since shortly after release. The 1975 has the Andy Warhol label. I had no interest in tasting it too early, since it had a reputation for being very acid, tannic, and raw when young, and evaluation of it proved very difficult for many critics. I just opened the case about a month ago. Today I opened a bottle.
The color still is rather deep scarlet with very little age showing around the rim. There is still tannin, but it is now smooth enough not to be a problem. There also is plenty of acidity, but it is now not raw and excessive. Now that the tannin and acid "screen" has lifted, the fruit has held and comes through well. There is the usual cassis, perhaps blackberries, a hint of a damp forest, and hints of chocolate and tobacco. The balance of the wine could be a bit better - it is no match for a 61 or 82 by any means - but the wine is now quite good drinking, especially with food. I expect mine to last many more years. There have been tasting notes for some bottles of Mouton 75 that proved a bit oxidized. Of course, at 30 years, some bottle variation is to be expected. I do not know if the less good bottles had been stored properly, if they had a cork problem, or if Mouton 75 was bottled in several batches that may not have been quite the same.
