A classic Martini recipe has 4-5 parts spirit and 1 part vermouth. If you order it “wet” that means it has more vermouth in it. If you order it “dry” it will have less vermouth. If you order it “very dry” you are just adding a splash or “showing the vermouth” to it. A dirty martini is a classic martini recipe with olive brine added to it.
2 oz Vodka
Spritz Dry vermouth in the glass
.25 oz Olive brine
Chill a martini or coupe glass as you mix this cocktail. Add ingredients to a mixing glass with ice. Stir until very cold. Strain into chilled martini glass. Garnish with olives.
