The Riesling vines are spread all over the 5.5ha of the Clos-Saint-Urbain in the Rangen Grand Cru vineyard. Being located at the opening of a cold and higher altitude valley, the Rangen enjoys a late ripening climate, but eventually catches up in October, when the steep slope (90%) and dark warm volcanic rocks allow the grapes to reach a high ripeness level. Zind-Humbrecht's dedication to terroir expression guides all winemaking practices, which include extended pressing cycles, abbreviated clarification cycles (to retain natural yeasts and proteins in the must), natural malolactic fermentation and extended aging on the lees. The wine is aged 18 months in 40-year-old French barrels.
