Rockstar Sugar Free PerfectBerry<br>Taste Rating: 3/5<br>Originality Score: 4/5<br>Caffeine: 32mg/100ml<br>Calories: 3 kCal/100ml<br>Purchased from: Asda<br>The opinion of people surrounding me whilst I drank this was overwhelmingly about the smell. I didn't notice that, but taste-wise it was highly perfumed! It was quite a synthetic berry flavour and in keeping with Rockstar tradition, very smooth to drink. The can size was smaller than usual at only 355 ml, and the associated caffeine kick was therefore lessened accordingly.<br><br>#energydrink #energydrinks #Berry #LargeCan #LowCalorie #UK
