Some time past someone on this board mentioned that "Ron, Flor de Cana" Rum from Nicaragua was similar to One Barrel.
Well the "7 year" stuff is very close! The subtle vanilla aroma/flavor is present but it is a little heavier, 80 proof! The cheaper dark version isn't as good though.
I found it at Spec's Liquor for the benefit of you Houston folks, even at the Hwy 6 store.
