The drink’s formulation includes carbonated water and glucose syrup (12%), providing its effervescence and sweetness. Apple juice from concentrate (1%) adds a natural fruity flavour, while citric acid contributes to its tangy profile. Flavourings enhance the overall taste, and caffeine serves as the primary stimulant. Sweeteners such as sucralose and acesulfame K offer additional sweetness without extra calories. Stabilisers like acacia gum, glycerol ester of wood rosins, and guar gum ensure a consistent texture, and Brilliant Blue FCF provides the drink’s distinctive colour. ​
