I think you may mean Josef Haupt. This is the maker of the wine. The wine will probably be a Riesling. Its 'drinkability' depends very much on its type (Auslese, Beerenauslese, Eiswein... to give a few examples). A basic Riesling will probably be oxidized and quite undrinkable. Even the more concentrated sweet wines (Beerenauslese, say) will probably be long past their best.

Anthony, I don't know this particular wine, but any of the botrytized riesling classes you mention, if made properly and stored reasonably, will be fine at that age, the TBAs better than the plain Ausleses, perhaps. I've had BAs and TBAs more than 40 years old that were gorgeous...
Even a Kabinett might be interesting, but anything below that will likely be either thin, or oxidized, depending on the storage conditions. Provenance is supremely important with any aged wine.
