Vermouth is an aromatized fortified wine, flavoured with various botanicals and sometimes colored. The modern versions of the beverage were first produced in the mid- to late 18th century in Turin, Italy.

What is equivalent to vermouth?

In the case of vermouth, whether dry or sweet, it's a fortified wine, so you need to replace it with another fortified wine. If you're out of dry vermouth and craving a Martini, try dry sherry, or Lillet Blanc. Cocchi Americano also works.

Is there liquor in vermouth?

Vermouth is fortified with additional alcohol (usually grape brandy), meaning they're higher proof than most wines, but nevertheless they are still moderately low-proof, about 15–18% alcohol by volume. Stir them over ice and top them with soda, and your drink clocks in at about 8 or 10% alcohol.
