The other day, I was given a bottle of a Swiss fizzy drink called Rivella. Apparently it is somehow derived from milk (whey plus lactic and other acids as well as sweeteners). I was intrigued to try it and would describe the taste as not unlike Refreshers, fizzy sweets available in the UK (doubtless also full of acids and sweeteners).

I didn’t fall in love with to the point that I’d hunt down more supplies (Rivella isn’t commonly available in the UK) but I’d happily drink it again if I wanted a sweet fizzy drink and it was available.
