I have been drinking Plantation Grande Reserve 5 Year. I thought it said 5 star on it, too. Pure Barbados rum, unlike my usual go to rum these days, the Plantation 3 Star, which is a blend of rums from three islands. I really like them both and the prices are right. I I will give the edge to the GR. Great in a Barbados Rum Punch, which is becoming a go to itself. Simple but excellent.
Correction: It is actually Plantation 5 Year, with no Grande Reserve. There is a Plantation Grande Reserve 5 Year, too, that I have not had.
