NEW BOTTLE DESIGN: Same great taste, now easier to Fizz, Mix, and Enjoy! Simply pour soda syrup into the bottle to about 1/2 inch above the fizzy water fill line (approx 1.5oz or 3 Tbsp). Always fizz water before adding any flavor. Your favorite flavor, Your Way. Add as much soda syrup as you like, make it as fizzy as your prefer. Whichever way you drink your flavors, make it at home with Sodastream's flavor syrups. Each beverage mix makes about 24 cans/9L of freshly carbonated flavors when prepared according to instructions. Bottle made with 100% recycled plastic (excl cap and label).
