- cook the water to remove any other disolved gasses
- Cool it down to as cold as you can. A sludge of ice and water is very close to zero °C
- keep some ice unmelted
- carbonate
This is a bit annoying to do especially step one (I skip it, it seems to help bit not to a huge degree) but it helps making very carbonated water to mix with the sirup
I think you'd end up paying less, too. I paid about 20 bucks for the concentrate bottle plus shipping, made 1.75L of it, thought it was fine but couldn't quite replace Coke in my diet, and didn't buy again. Had I done it all from scratch, I'm pretty sure I would've paid more and had a bunch of essential oil bottles leftover, going to waste.
I used like half the amount of sugar the cube-cola recipe recommended, because it seemed high. It wasn't Coke sweet but it was still plenty sweet for a soft drink, to my palette.
EDIT: Originally said 1.75 ml, meant to say Liters.
