Berta produces grappa, a grape-based pomace Italian brandy. The modern state-of-the-art Roccanivo distillery owned by the Berta family at Casalotto di Mombaruzzo opened in the grape harvest of 2002, a historic vintage for this family/business and for the economic development of the Asti wine sector. The grappa is processed as little as possible to retain the purest flavor of the pomace.
