Fin ’n Tonic – Minty Gin & Tonic Highball Twist

The Fin ’n Tonic is a mint-kissed take on the classic gin and tonic, adding a subtle layer of peppermint to an already crisp and refreshing highball. It keeps the structure you expect, but introduces a cooling twist that stands out without overwhelming the drink.

Background

The gin and tonic dates back to British colonial India, where quinine-laced tonic was used medicinally and mixed with gin for taste. Over time, it became one of the world’s most recognized highballs. The Fin ’n Tonic builds on that legacy by incorporating peppermint schnapps, a liqueur long associated with European digestifs and festive cocktails.

What You’ll Need

Ingredients

• Gin – the botanical backbone that defines the drink
• Peppermint Schnapps – adds a cool, minty accent
• Tonic Water – brings bitterness and effervescence

Substitution ideas:

• No peppermint schnapps? Use a small amount of crème de menthe or fresh mint
• Prefer less bitterness? Swap tonic for soda water + a squeeze of lime

Equipment

• Highball glass
• Bar spoon

A Cooler Kind of G&T

This drink stands out by layering a cooling mint note over the familiar gin and tonic profile. The peppermint doesn’t dominate when used sparingly, instead adding a crisp finish that makes the drink feel sharper and more refreshing, especially in warm weather.

Substitutions & Variations

• Swap gin for vodka for a cleaner, mint-forward profile
• Add a lime wedge for brightness and balance
• Try a floral gin to contrast the mint with soft botanicals

Helpful Tips

• Always add tonic last to keep carbonation lively
• Use fresh, solid ice to slow dilution
• Start light on schnapps and adjust to taste
• Garnish with mint or lime for a more complete presentation
