Anyone buying these has to realise that they are unsweetened, lightly flavoured waters, and not soft drinks. But anyway, this is an odd flavour. I was pretty keen cos I love grapefruit, and with a name like “pamplemousse”, what could go wrong- but it wasn't at all grapefruity. I love the others, but will steer clear of pamplemousse in the future. On the bright side, it's fun to say.
