The frightfully-priced 1992 Riesling Eiswein Gold Capsule is stunning. Not even a soothsayer could accurately predict how long this wine will last, but my guess is 30-40 years. Diel is considered to be one of the most serious estates in Germany. He is also one of that country's wine writers. The selection of 1992s I tasted from Diel ranged from impressive to awesome. However, Diel is not shy about pricing; these wines are expensive.Importer: Rudi Wiest Cellars Int., Carlsbad, CA.
