Fizzy-Pop Lemon Up is our version of Sprite/7up and is crystal clear. Caffeine-free. 2L jug.
Pops are a 5:1 ratio. The colder and more carbonated your water the less syrup you'll use. Start with aprx 125ml or 3-4 pumps for a 1L bottle and adjust +/- from there. Experiment with the number of pumps to find the amount that suits your taste.
