From a 0.5ha parcel planted in 1976 on clay-limestone soil at 350m above sea level. Yields are lower here, 4000kg/ha.  The grapes are crushed and immediately pressed in the basket press.  Fermentation occurs in used barriques. Aging took place in used barriques for 12 months. 21 is the address of the cellar and San Michele is the name of the contrada where the vineyard is located.
