With SodaStream, you're in control of both flavor and carbonation. In general, use a capful of Sparkling Drink Mix for each liter of sparkling water. If you like it sweeter, add more! If you like it less sweet, use less.
1. Pick your favorite flavor
2. Sparkle a bottle of fresh, cold water with your sparkling water maker
3. Tilt the bottle at an angle and add a capful (if you like it less sweet, use less!) of flavor to your bubbly water
4. Gently shake the bottle to disperse flavor throughout
5. Bask in the bubbles and enjoy :)
