This wine is made from 100% Malvasia Bianca. After harvest, the grapes are left to dry on straw mats for one month and then softly pressed and lightly macerated. Fermentation is carried out in new small French barrels and the fermented wine ages in barrel for three to six months prior to an additional year in bottle. This wine is named for a varietal that was once found in Gravina but is now extinct. Documents from the 1700s mention a vine called Gravisano, from which very small amounts of a rich and sweet wine were made for special occasions.
