Some how I don't see pirates singing "yo ho, yo ho," and swinging a bottle of this around. Then again, I don't no what hos they would be calling on ship so that song is kind of dumb.
Anyway, Kirkland Signature Original Spiced Rum is not as good as Vodka but hits a good deal harder. The favor is not that great and I'm sure modern pirates would love to have a bottle.
Drink if you like rum, pass if you're not that kind of a man.
