Domaines Schlumberger has an enormous holding of more than 130 hectares in Guebwiller and is the largest Grands Crus producer in Alsace. In some of the steepest, terraced vineyards horses are still used and no expense is spared in the pursuit of excellence. In a region where quality is utterly dependable, Schlumberger stands as a benchmark. Production methods are traditional and the resulting wines are very fine.
