Angostura 7 Year Old Rum. To create Angostura 7 Year Old rum, the Master Blender selects rums that have been aged for at least 7 years. The blend is returned to bourbon barrels to combine the flavors that will give this unique distillate. Angostura 7 Year Old, with notes of maple, chocolate, honey and butterscotch, has a full body. It is drunk neat or with ice, while it combines wonderfully in the most creative cocktails.
