“Gran Reserva.” “Maestro de Ron.” These are terms that one would expect to see applied to a dark, old, well-aged rum, but Bacardi is taking the unusual step of slapping them on its latest release, a white rum. Bacardi Gran Reserva Maestro de Ron is “designed to elevate the simple cocktail experience” and is intended as “the ultimate white mixing rum.” As with most white rums, it is aged in white oak, then filtered to white — though Maestro de Ron is said to be “double aged” — each barrel is aged for at least one year, then the barrels are married and aged again for a further three months. That aside, the results are fine and the rum is capable, if less inspired than the name might imply. The nose of this spirit — not quite white but rather the palest shade of gold — strikes familiar white rum chords. Hefty vanilla notes with a modest touch of fuel-like character give it that unmistakable Bacardi aroma. On the palate, the vanilla is backed up with more traditional white rum notes, including ripe banana, pencil shavings, coconut husk, and a touch of cinnamon — for the most part they are all flavors that would play nicely in tropical cocktails.
