Abstract
Vermouth is a wine derivative fortified and flavored with botanicals (Fig. 1) [1]. Traditionally, red vermouth is pigmented with caramel. We used natural grape anthocyanins to improve the color and, at the same time, increase flavonoid contents, molecules with positive repercussion on health. The anthocyanins were extracted from grape skins using acidified water as solvent and physically assisted by ultrasounds. Commercial anthocyanins extracts from grape by-products were also used to improve vermouth color. Vermouths were aged using yeast lees biomass and also using chips from different types of woods: ?palo rojo?, cherry, cedar, oak and ebony. During 3 months.
