Monster Ultra Fiesta<br>Taste Rating: 3/5<br>Originality Score: 2/5<br>Caffeine: 30mg/100ml<br>Calories: 3 kCal/100ml<br>Purchased from: Tesco<br>And the second Monster flavour of the year (2021)... this time it's another tropical one but in sugar-free form. Ultra Fiesta is a mango flavoured beverage in a large 500ml can. It's mild and refreshing, and easy to drink due to the lack of sugar making it less sickly than full fat versions.<br><br>#energydrink #energydrinks #LargeCan #LowCalorie #Mango #UK
