Vermouth is liquor made from wine, with special herbs and spices such as cardamom, cinnamon, marjoram, and chamomile added for flavor. Some refer to it as fortified wine, but this is incorrect, because fortified wine technically has alcohol added to increase its potency. The history of Vermouth goes all the way back to the 18th century when it was used as a healing tonic drink because of the herbs that went into its creation.
Some vermouth are sweetened and some are bitter and dry. This distinguishes the two main types of vermouth: dry and white, or sweet and red. Dry vermouth is typically around 18% alcohol while sweet vermouth is around 15%.
