The relationship between vermouth and martinis.

The martini cocktail is a popular drink that can be made with vermouth. Sweet vermouth is added to reduce the alcohol content and add sweetness and botanicals. Dry vermouth brings out the herbs and botanicals of the vermouth, with extra dry vermouth bringing even more. The difference between a Wet and Dry Martini is the type of vermouth used. Vermouth is a fortified wine infused with botanicals, but it's not necessary to have it in a Martini.
