No idea about the boabab flavour but within http://www.flyertalk.com/forum/japan...l#post16804611 an intrepid FTer bravely tried the caribbean gold flavour

I've only had the pepsi white. tab mixed with calpis is a good description. I like calpis, but the tab flavour ruined it.

I asked my parents to buy me Antesite whilst they drove through France, but not the version with aniseed. I got an email today saying they found some. One of the bottles is apple and cinnamon flavour, that should be interesting (Antesite is one of the strangest soft drinks I've ever tried. It's made with liquorice extract and this is naturally sweeter than any sugar, so you get these intense flavoured sugar free concentrates and you add a few drops to a glass of water. I guess it's an acquired taste and is horribly difficult to get hold of, especially if you're a fellow aniseed hater)

EDIT: I just realised that when Pepsi Azuki was mentioned it wasn't a joke. Urgh!

This ranks high on my vile list - perhaps even more (but not much more) than Dr Pepper
