Rockstar Pure Zero Guava

A fruity and almost tropical tasting drink with zero* (read that as 4kcal/100ml) calories. It’s nice but pretty sickly even when straight out of the fridge. At the time of writing this, Rockstar Energy still haven’t acknowledged any of their Pure Zero products on their UK web site, but if you look at the international US version you can get a taste of other flavours they may be releasing under this label.
