Colorado Martini – Gin, Vodka, Dry Vermouth and Bitters Cocktail

The Colorado Martini is a dry split-base cocktail that combines gin and vodka with dry vermouth, aromatic bitters, and a tiny amount of salt. Gin brings botanicals, vodka keeps the profile clean, and the seasoning gives the finish a subtle savory edge.

Gin and Vodka in Equal Measure

Using both spirits gives the drink a hybrid character: more aromatic than a straight Vodka Martini, but cleaner and less juniper-driven than an all-gin version. Dry vermouth ties the two bases together.

What You'll Need

Ingredients

• Gin – adds juniper and botanical character.
• Vodka – gives the split base a cleaner edge.
• Dry vermouth – supplies herbal wine notes and softens the spirits.
• Angostura bitters – adds spice and aromatic depth.
• Salt – seasons the drink in a very small amount.
• Olive – provides a savory garnish.

A softer gin makes the split base more seamless. Orange bitters can replace Angostura for a brighter accent.

Equipment

Use a mixing glass, bar spoon, jigger, strainer, and chilled cocktail glass.

The Pinch of Salt

Salt works here like seasoning in food: it should sharpen the other flavors rather than taste salty on its own. A true pinch is plenty alongside the bitters and olive garnish.

Substitutions & Variations

Use all gin for a more botanical version or all vodka for a cleaner one. A lemon twist can replace the olive if you prefer citrus aroma over savory garnish.

Helpful Tips

Use only a true pinch of salt; more can quickly dominate. Stir with dense ice until the drink is cold and slightly diluted, and keep opened vermouth refrigerated.
