**Barr Cherryade PM 500 ml** is a refreshing, sugar-free cherry-flavoured sparkling soft drink that captures the bright, tangy sweetness of ripe cherries. It’s crafted with **carbonated water, citric acid (for tartness), flavourings, natural colourings (anthocyanins and plain caramel E150a), sweeteners (acesulfame K and sucralose), and a preservative (sodium benzoate)**. The beverage is low-calorie (about 1 kcal per 100 ml) and contains no fat, sugars, or protein . Importantly, the label includes a **warning that it “contains sweeteners,”** which also implies a **source of phenylalanine**, alerting consumers—particularly those with phenylketonuria (PKU)—to the presence of such ingredients.
