Which type of vermouth is typically used in a dry Martini?

The type of vermouth typically used in a dry Martini is dry vermouth. This style of vermouth is characterized by its crisp and less sweet profile compared to sweet vermouth, which is often used in cocktails like the Manhattan. In a dry Martini, the dry vermouth complements the gin by adding a subtle herbal flavor without overwhelming the drink with sweetness.

Using dry vermouth helps to maintain the classic dry flavor profile that makes the Martini a timeless cocktail. It is often recommended to use just a small amount of dry vermouth, or sometimes even to rinse the glass with it, to allow the primary gin flavor to shine through while still providing a hint of complexity from the vermouth.
