Il Palazzino's Vinsanto is made from white Malvasia di Toscana grapes along with a very small amount of Trebbiano Toscano. The grapes are picked in late September and hung fromiron hooks in well-ventilated rooms, where they are allowed to wither slowly for several months. The concentrated juice from these grapes, high in sugar and flavor, is sealed in small chestnut or oak barrels to stop the fermentation once the oxygen inside is used up. After five years, the Vinsanto is ready for bottling. At the end of this long process, the yield is usually less than 2,000 liters of Vinsanto per hectare.
Every year, Il Palazzino produces about 2,000 375 ml. bottles of Vinsanto.
