Fanta Strawberry Bag-in-Box (BIB) is a 2.5-gallon concentrated fountain syrup designed for use with commercial soda fountain dispensers and compatible consumer carbonation systems. The syrup is mixed with carbonated water at a 5:1 ratio (five parts water to one part syrup), yielding approximately 15 gallons or 160 twelve-ounce servings per box.

The bag-in-box format is a collapsible inner bag sealed inside a corrugated box, allowing the syrup to be used in any orientation without introducing air. This packaging prevents oxidation and ensures every last drop of syrup can be dispensed. The product connects via a standard Coca-Cola BIB connector for commercial machines, or a BIB tap valve adapter for home use.

No refrigeration is required prior to opening. Syrup should be stored in a cool, dry place between 40°F and 77°F (4°C–25°C) for best quality. Produced by The Coca-Cola Company under the Fanta brand.
