Barq's Root Beer B.I.B. (Bag-In-Box) is a 2.5-gallon concentrated soda fountain syrup designed for commercial beverage dispensing systems. Made by The Coca-Cola Company, this foodservice-grade concentrate delivers Barq's signature bold, biting root beer flavor with its distinctive sassafras and vanilla notes that fans have enjoyed since 1898.

The flexible bag-in-box design is optimized for professional soda fountain equipment, allowing the inner bag to collapse as syrup is dispensed so the container can be positioned in any orientation to extract every last drop. This syrup is mixed with carbonated water at a 5:1 ratio (five parts carbonated water to one part syrup), yielding approximately 15 gallons of finished beverage or around 160 standard 12-ounce servings per box. Barq's Root Beer is caffeinated and Kosher certified, with a 75-day shelf life once tapped. This product is intended for commercial bag-in-box soda dispensing systems and is available through Costco Business Centers and foodservice distributors.
