I bought half a case of this wine when it was first released, and drank it up when it was rather young. In the 1990s it was a pleasant and enjoyable sweet wine, but nothing to write home about.
I just now happened to notice the last bottle lurking in a corner of my cellar. I wasn't expecting very much, given that this is Siegerrebe (a grape that produces lots of sugar, but isn't noted for aroma or flavor or acidity), and that it's twenty-seven years past the vintage date.
I was pleasantly surprised.
The color is the full burnished gold that you expect from mature German Beerenauslese. The aroma is what you'd expect from Siegerrebe--shy, with lemon nuances, not the complexity you'd get from Riesling. There's some of the tell-tale botrytis shoe-polish in the aroma, as well. In the mouth the wine has a thick, glycerine-like texture, and complex citrus-and-botrytis flavors, with some tropical fruits. There's enough acidity to insure that the flavors dance on the palate for about a minute after you swallow the mouthful of wine.
Double Larry Curly. Punching well above its weight, and a very pleasant surprise. If you're fortunate enough to have any of this in your cellar, there doesn't seem to be any hurry to drink this up.
