Irn-Bru Energy Zero Sugar<br>Taste Rating: 5/5<br>Originality Score: 4/5<br>Caffeine: 32mg/100ml<br>Calories: 3 kCal/100ml<br>Purchased from: WH Smith<br>Yeah! Irn-Bru, but with caffeine! Much like the full fat version this is a great success in my eyes. It's basically Irn-Bru in flavour but with that caffeinated kick to get you moving. I prefer this zero sugar version for health reasons... yeah, you've got to be thinking of your health when you're testing hundreds of energy drinks... but also the lack of sugar in my opinion does improve the aftertaste of energy drinks including this one.<br><br>#energydrink #energydrinks #LargeCan #LowCalorie #UK
