I rated it a six. However, I was told the bottle was only about four dollars. For that price, it's an 11! More seriously, it's not bad at all. It is smooth enough to be a sipping rum, and it is completely unobjectionable in every way. But, that is also the issue with it, as there is nothing that stands out as being wonderfully tasty either. I'd say it tastes like a common, good quality, standard rum should, and that is not a bad thing in any way. In fact, I've not found a more "standard" rum anywhere.
Smells like nail polish remover but thankfully tastes better. Strong caramel sweetness masking a young rum IMHO. Not a very pleasant after taste. Probably ok as a mixer with cola. Plenty of better 12 yr rums out there.
