Havana Club Rums
Classified as their "versatile gold mixer" -- a golden rum that's created from a blend of rums aged up to 5 years -- a blend of old and young rums. It has the lightness of a white rum with the aroma and some nuance of dark rums. This combination means it is perfect for a Mojito or Cuba Libre. Rum and cokes were one of my first consistent drinks of choice - meaning at 18, I was getting shit-faced on Bacardi and Cokes. The Cuba Libre is worth revisiting with the Havana Club Añejo Especial and a unique cola like Fentimans. Add 2oz. of rum and 1oz. lime juice in a tall glass over ice, top up with Fentimans and garnish with a slice of lime. Also try blending lemon and lime juice.
Añejo 7 Años
This is the classic - it's what the folks at Havana Club call "the epitome of Cuban rum." Perfect on its own, exhibiting notes of vanilla, cedar and tobacco with a richness that is not quite sweet, but balanced. For a richer daiquiri, this is an ideal rum. Also try substituting this rum for rye / bourbon in a Manhattan. Another wonderful cocktail for rum is Tony Conigliaro's El Presidente (with rum, dry curaçao, sweet vermouth and grenadine).
Selección de Maestros
This rum is "the expression of six Cuban Maestros Roneros collective know-how, led by Don Jose Navarro." They pick the best of their aged rums, blend them, and further age the blend in selected barrels. The final blend is bottled at barrel proof (45%). It's not a cheap bottle, so not sure it's "worth" (a subjective term) mixing, but it's a knock-out when you simply add a large chunk of ice to it.
