To be clear, it made about 1.75L of syrup, not cola. I kept the cola syrup jug in a fridge for like a year, and when I wanted a glass of "cola" I'd add about an oz of the syrup concentrate to a glass of carbonated water (which I pre-carbonated with my DrinkMate), and stirred to combine.

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.

An oz is ~29.57 ml (mililiters), so I think perhaps you meant that you made 1.7 l (liters)?

Do you mean L? ml to me would be millilitres and one fluid ounce is ~30ml.

How is the cleanup with DrinkMate? Washing everything was my primary problem with SodaStream.
