The primary ingredient of Coca-Cola is carbonated water. This carbonated beverage also includes other key components such as high fructose corn syrup or sucrose, caramel color, phosphoric acid, caffeine, citric acid, and natural flavors, which contribute to its distinct taste. The combination of these ingredients creates the well-known flavor profile of Coca-Cola. The carbonation, achieved by infusing water with carbon dioxide, gives the drink its effervescence. Coca-Cola has a long history and remains one of the most popular soft drinks globally, recognized for its iconic branding and strong market presence.
