Technological potential
The bunches are medium, fairly loose with a long and not very lignified peduncle. The berries are medium to large in size and become intensely and homogeneously colored before the grapes reach full maturity. The skin is fairly thin and the pulp is firm, juicy with a neutral flavor and moderate organoleptic quality. Prima has a good storage and transport capacity.
