C4: Cosmic Rainbow<br>Taste Rating: 4/5<br>Originality Score: 5/5<br>Caffeine: 32mg/100ml<br>Calories: 5 kCal/100ml<br>Purchased from: Local Store<br>Oooh now this one is interesting. There's no clue on the can as to what 'cosmic rainbow' flavouring might actually be so you're going to have to take my best guesses here. There's a note of blackcurrant for starters, so I think that's the main flavour, but it's also sweeter and slightly tangy so I reckon there might be some fresher tasting berries in there too. Something like raspberry maybe, if you mixed blue raspberry with blackcurrant I think you would come up with this flavour... maybe I'll do some experimenting and find out. Whatever the case, it's quite nice!<br><br>#energydrink #energydrinks #LargeCan #LowCalorie #UK
