Fifty-Fifty Cocktail - Equal-Parts Gin & Dry Vermouth Martini

The Fifty-Fifty Cocktail uses equal measures of Gin and Dry Vermouth, making vermouth a true partner rather than a rinse or accent. A dash of Orange Bitters is a well-established modern addition, though historical equal-parts versions do not always include bitters.

Background

Equal-parts gin-and-French-vermouth drinks were documented in early-20th-century cocktail books, including Hugo Ensslin's 1917 work. The Fifty-Fifty belongs directly to the Martini family, but historical formulas and later bar versions vary on bitters and garnish. Equal parts gin and dry vermouth are the defining structure.

What You'll Need

Ingredients

• Dry Vermouth - provides herbal, wine-based dryness and lowers the drink's overall intensity.
• Gin - supplies juniper, citrus, and botanical structure.
• Orange Bitters - adds a restrained citrus-spice accent in this version.

A fresh, refrigerated dry vermouth matters more here than in a very dry Martini because it represents half the drink. Different gin and vermouth pairings can shift the profile significantly.

Equipment

• Mixing glass
• Jigger
• Bar spoon
• Strainer
• Nick & Nora Glass

Vermouth Is Half the Drink

The Fifty-Fifty rewards treating vermouth like wine rather than shelf-stable seasoning. Proper refrigeration, fresh bottles, and controlled dilution preserve the floral and herbal detail that makes the equal-parts formula distinct from a conventional dry Martini.

Substitutions & Variations

• Omit Orange Bitters for a historically simpler equal-parts version.
• Use a citrus-led gin for a softer profile.
• Choose a more savory dry vermouth for additional herbal depth.
• Garnish with lemon for brightness or an olive for a more savory presentation.

Helpful Tips

• Refrigerate opened Dry Vermouth.
• Chill the serving glass before stirring.
• Use firm ice and stir until fully chilled.
• Do not overdo the Orange Bitters; one dash is enough here.
• Taste different gin-vermouth pairings because both bottles have equal influence.
