Saw this nestling on the shelf in my regular grocer yesterday there was not great deal on the label other than "Aniseed" in the ingredient list to let on about it's flavour.
So after a good chilling I had sip and ewww I think we'll file this under "acquired taste". It's very medicinal more so than say Pernod or even Doctor Pepper. The difference with Pernod is there's not even the promise of alcohol to make the bitterness acceptable. It's somewhat like neat Campari but with perhaps more sweetness. It's from a group of drinks from the Caribbean and seems to be from root beer fermented Ginger ale school of pop, but I'm not sure I'd try it again. First time imbibers are warned of its laxative properties according to wiki (thankfully I only managed a few sips!)
