Rockstar Zero Sugar Blueberry<br>Taste Rating: 4/5<br>Originality Score: 3/5<br>Caffeine: 31mg/100ml<br>Calories: 2 kCal/100ml<br>Purchased from: B&M<br>Quite a light flavoured blueberry drink. It's neither watery nor too strong, a good balance and zero calories too. Blueberry is a good flavour for energy drinks I think because it's different enough from the regular mixed fruit flavours but doesn't have the harshness of other berry flavoured drinks.<br><br>#energydrink #energydrinks #Blueberry #LargeCan #LowCalorie #UK
