Same vintage as last time but there was a sour tinge to this that built up over time, kid of like that infected-barrel quality that Big Block beers tend to have. By the end of the glass I was not enjoying it anymore.
Not a ton of rum in the flavor (although you can smell it), but this is pretty much as enjoyable as the base beer. Hard to say exactly, though, since I haven't had Coco Jones in a while. Lightly sweet, smooth, coconut. Nothing poking out around the edges.
