The Willm vineyard is located in the Barr region of northern Alsace at an altitude of 200-400 meters, extending from the mountainous base of the Vosges to the plains of Alsace and the Rhine. Bordered by the Vosges Mountains to the west, the Barr hillsides benefit from a dry and sunny microclimate thanks to their south-southeast exposure, optimal for cultivating the vines. The fluctuation between warm days and cool nights in autumn is conducive to a slow, prolonged grape maturation. The diverse soils are a product of the region’s diverse landscape. The mountainous Vosges make way for smaller hills which stretch into various flatlands—just a few of about a dozen geological formations that comprise the region’s landscape. The vineyard itself consists primarily of granite and clay-limestone soils, while the coastal marine environment contributes to the terroir’s mineral-rich quality.
