Technological potentiality
Cualtacciu's bunches are medium in size and compact. The berries are small to medium, simple-flavored, with a moderately thick skin and a moderately juicy pulp. This variety produces light-bodied wines with a pronounced, intense acidity, that are expressive on the nose, with citrus fruits and exotiques fruits notes.
