Grappa
Grappa is a pomace brandy originating from Italy or Italian Switzerland. This is distilled from the fermented alcoholic press residues from wine production, the pomace. Grappa has a minimum alcohol content of 37.5 percent by volume. The most popular grappas are made from the marc of red grapes. The wood of storage barrels can be used to determine color and taste. Grappas from cherry wood barrels have a sweeter taste, those from oak barrels have a tart taste. A long storage in chestnut wood barrels brings a brownish color. Since the skins of white grapes still contain sugar, they are infused with must and fermented again. The resulting wine is then distilled. This is how grape brandies are made from white varieties.
