The Shamrock brings whiskey, herbal notes, and mint into one short cocktail. The version below uses Irish whiskey with dry vermouth and small measures of two strongly flavoured liqueurs. Keep the mint restrained so the whiskey still comes through.

Ingredients — One Serving

  • 45 ml Irish whiskey
  • 15 ml dry vermouth
  • 5 ml green crème de menthe
  • 5 ml green Chartreuse
  • Ice
  • A small mint sprig, optional

How to Make It

  1. Chill a small cocktail glass.
  2. Add the whiskey, vermouth, and liqueurs to a mixing glass filled with ice.
  3. Stir until well chilled and lightly diluted.
  4. Strain into the chilled glass and add the optional mint garnish.

Adjust the Mint Carefully

Crème de menthe can quickly dominate a drink. Start with the small measure above and adjust only after tasting. Different brands vary in sweetness and intensity, so a little experimentation is more useful than adding a large pour.

Choosing Your Whiskey and Vermouth

A smooth Irish whiskey is a useful starting point. Dry vermouth keeps the drink lighter than a sweet-vermouth variation. Refrigerate opened vermouth and use it while its flavour is still fresh.

Recipe Notes

This is a suggested house-style version rather than a recovered copy of the original article. If you substitute another herbal liqueur for green Chartreuse, expect the flavour to change. Serve as one measured cocktail and enjoy in moderation.
