Cave de Ribeauville is the oldest wine cooperative in France... and one of the most award-winning producers of the Alsace region. Their vineyards of Grand Cru Osterberg, one of eight Grand Cru lieux-dits in their holdings, are located on the steep, sun-drenched hills of Alsace. Located south of Strasbourg, facing the Vosges Mountains and flanked on the east by the Rhine River and Germany's Black Forest, this vineyard is perfectly situated.
