Frost a martini glass in the freezer or refrigerator. (alternatively fill martini glass with ice, add water while mixing drink) In a cocktail shaker filled with ice, combine the Seven Jars Vodka and vermouth. Shake vigorously until the drink is thoroughly chilled. Pour the ice water out of the martini glass and shake any excess water from the glass. Strain the drink into the martini glass. Garnish with olive and serve.
