Introduction

The Old-Fashioned is a cocktail that has stood the test of time, celebrated for its simplicity and elegance. Traditionally made with whiskey, the Old-Fashioned has seen countless variations, each bringing its own unique flair to the classic formula. Enter the Rum Old-Fashioned—a delightful twist that swaps the whiskey for aged rum, creating a cocktail that's smooth, rich, and perfect for rum enthusiasts looking to elevate their at-home mixology game.

Rum, with its deep, complex flavors, offers a fresh take on the Old-Fashioned, showcasing the spirit's versatility beyond tropical cocktails. Using a 12-year-aged rum brings depth and maturity to the drink, while Demerara syrup adds a touch of caramel sweetness, and orange bitters provide a zesty counterbalance. This combination results in a cocktail that's both familiar and novel, making it an excellent choice for those seeking a sophisticated sip.

Did you know that the Old-Fashioned is often considered the first true cocktail? Its origins date back to the early 19th century, when it was simply known as a "whiskey cocktail." Over time, the name evolved to reflect the drink's traditional preparation method, and today, it's a staple in cocktail bars worldwide. The Rum Old-Fashioned pays homage to this heritage while offering a fresh twist that rum lovers will adore.

Ingredients

  • 1 tsp 1:1 Demerara Syrup
  • 2 dashes House Orange Bitters
  • 2 oz 12-Year Rum
  • 1 Lime Peel

Creating a Rum Old-Fashioned requires just a handful of quality ingredients. Here's what you'll need to mix up this refined cocktail:

  • 1 tsp 1:1 Demerara Syrup: Demerara syrup is a richer alternative to simple syrup, made from Demerara sugar. It adds a deep caramel flavor that complements the rum beautifully.
  • 2 dashes House Orange Bitters: Orange bitters bring a citrusy brightness and complexity to the cocktail, enhancing the rum's natural flavors.
  • 2 oz 12-Year Rum: Choose a 12-year-aged rum for its smoothness and depth, which are essential for a well-rounded Old-Fashioned.
  • 1 Lime Peel: A lime peel adds a fragrant zest, elevating the drink's aroma and providing a refreshing finish.

Instructions

Crafting a Rum Old-Fashioned is all about precision and balance. Follow these steps to create a cocktail that's sure to impress:

  1. Combine the Demerara syrup, bitters, and rum in a mixing glass and stir with ice cubes.
  2. Strain over fresh ice into an old-fashioned glass.
  3. Twist the peel over the surface of the cocktail, rub the rim of the glass with the peel, and drop in the drink to serve.

Tips

  • Use large, clear ice cubes to minimize dilution and keep your Rum Old-Fashioned perfectly chilled.
  • Experiment with different aged rums to discover your preferred flavor profile. Each rum brings its own unique character to the cocktail.
  • For an extra touch, consider flaming the lime peel before adding it to the drink. This enhances the aroma and adds a subtle smokiness.
  • If you prefer a sweeter cocktail, adjust the amount of Demerara syrup to suit your taste.

Conclusion

The Rum Old-Fashioned is a testament to the versatility of rum and the enduring appeal of the Old-Fashioned cocktail. With its rich flavors and elegant presentation, it's a drink that's sure to impress guests and satisfy your craving for a sophisticated sip.
