Rum and Tonic

The Rum and Tonic is a simple yet elegant two-ingredient cocktail that serves as a wonderful alternative to the more common Gin and Tonic. The choice of rum can dramatically alter the drink's profile, from light and grassy with a white rum to rich and spicy with an aged or dark rum. The bitterness of the tonic water beautifully balances the inherent sweetness of the sugarcane-based spirit, creating a refreshing and easy-to-drink beverage suitable for any time of year.

Backstory

While the Gin and Tonic has a well-documented history with the British Army in India, the Rum and Tonic's origins are less specific. It likely emerged as a natural variation in rum-producing regions of the Caribbean and Latin America, where both rum and tonic water were readily available. It has gained popularity in recent years as drinkers explore alternatives to gin, discovering how well the diverse world of rum pairs with tonic's dry bitterness.
Origin
The exact origin is unknown, but it is considered a modern classic variation that became popular in rum-producing regions like the Caribbean. Its rise in global popularity is a more recent phenomenon, occurring in the 21st century alongside the craft cocktail movement.

Ingredients

This simple highball requires just three components: your choice of rum, a quality tonic water, and a fresh lime for garnish and a touch of acidity.
  • Aged Rum60 ml / 2 oz
    A good quality aged or gold rum offers notes of vanilla and spice that complement the tonic. A light white rum will create a crisper, more gin-like profile.
  • Tonic Water120 ml / 4 oz, or to top
    Use a high-quality, well-chilled tonic water. Indian or Mediterranean styles work well.
  • Lime Wedge1
    Used both for a small squeeze of juice and for the garnish.

2. Pour the rum over the ice.
3. Slowly top with chilled tonic water to preserve carbonation.
