The primary modern flavoring ingredients in a cola drink are citrus oils (from orange, lime, and lemon peels), cinnamon, vanilla, and an acidic flavorant.[7][8] Manufacturers of cola drinks add trace flavorings to create distinctively different tastes for each brand. Trace flavorings may include a wide variety of ingredients, such as spices like nutmeg or coriander, but the base flavorings that most people identify with a cola taste remain citrus, vanilla and cinnamon. Acidity is often provided by phosphoric acid, sometimes accompanied by citric or other isolated acids.
