The powerful 1991 Riesling Rangen-Clos St.-Urbain displays a huge, fragrant, flinty, cold steel, slate-like nose, full-bodied, crisp, deep, dry flavors, sensational focus and definition, and a long, rich finish. It should last for up to a decade.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.
