The 1991 is the most opulent example I have tasted from this vineyard, located at the bottom of the famed Hengst vineyard. It is rich, with more opulence and alcohol than usual. Olivier Humbrecht stated it was produced from microscopic yields of 20 hectoliters per hectare. This big, forceful Riesling should drink well for another decade. The Riesling Clos Hauserer is usually a wine that needs some time in the cellar. As extraordinary as the 1989 and 1990 Zind-Humbrecht wines are, the 1991s, largely because of the difficulties presented by the vintage, are even more amazing. Readers must keep in mind that for the top Alsatian producers the situation is much like that in Burgundy - only tiny quantities of wine available. Between 50 and 150 cases of each wine is the entire allocation for the American market.I do not ever remember a producer in a so-so year making such magnificent wines! Bravo to Olivier and Leonard Humbrecht!Zind-Humbrecht wines are imported by Wine Markets International, Syosset, NY and Kermit Lynch Wine Merchant, Berkeley, CA.
