Grand Cru Rangen de Thann is Alsace's most extreme vineyard: the southernmost, steepest (45° slopes), and only volcanic Grand Cru. The soil is graywacke, tuff, and volcanic ash from 350 million years ago. While Pinot Noir can't yet claim Grand Cru status here, the wines taste of smoke, gunpowder, and volcanic minerals unlike any other French Pinot.
