4. Mixing

Pure water and flavour syrup are transferred to the bottling unit, where they are mixed together in strict proportions in a special vessel – the agitator – and the drink is carbonised.

Did you know?

  • CO2 is delivered to the factory in liquid form in a special multi-ton truck, pumped into a tank and then added to the water through an evaporator, which changes it from liquid to gas
  • CO2 is mixed with the syrup in the agitator. The water is cooled first so that the gas can be better dissolved
  • To carbonate the water, first most of the oxygen has to be removed from it
  • About 30g of CO2 is used for one two-litre bottle
