Results

More carbonation is needed. Attempt 5 and 6 are the closest to original club-Mate, but are still distinctly different.

Next up

The strong carbonation is te main feature that all attempts are missing, that is why next attempts will try to improve this. Two routes that might be promising are:

1. Using a keg that is pressurised using a CO2 tank
2. Creating CO2 in the bottles using a baking soda + citric acid reaction

The colour is also too yellow. The original Club-Mate uses E150D (Caramel colour). Future attempts will also include this food colouring.
