An Añejo Rum Highball is smooth, lightly sweet, and effervescent, with the rich, caramel-tinged depth of aged rum balanced by sparkling water. The curaçao and squeeze of lime along with the twist can brighten the profile, while the bubbles keep it refreshing and easy-drinking. It drinks crisp and approachable, letting the nuanced flavors of the rum shine in a simple, elegant presentation.
