Vermouth is an aromatic fortified wine that is flavoured with various botanicals and sometimes has colour added. Vermouth is made from a neutral grape wine or unfermented wine must and has additional alcohol and botanicals added.
Initially, vermouth was used for medicinal purposes but was later offered as an aperitif and ingredient in cocktails. Traditionally, there were two types of vermouth: dry and sweet. Now there are additional styles that have been created to meet demand. Common newer styles are extra-dry white, sweet white (blanc or bianco), red, amber (ambre or rosso), and rosé.
