This wine is named after a varietal that was once found in Gravina, but has since become extinct. Documents from the 1700's mention a vine called Gravisano, from which very small amounts of a rich and sweet wine were made for special occasions. After harvest, the grapes are left to dry on straw mats for one month and then softly pressed and lightly macerated. The wine is then fermented aged in oak casks for 36 months before an additional six months in bottle.
