Wort Cooling

Process description

Before fermentation the original wort must be cooled to between approximately 10°C to 20°C. Cooling usually takes place with water, an alternative cooling medium or with a mechanical cooling device.   

Gas application

Instead of mechanical cooling, the cold content of a cryogenic gas can be used to cool the original wort. Liquid carbon dioxide is usually used for this purpose.  


  • Low energy costs
  • Reduced CO2-emissions
  • Simple integration into existing system  
  • Avoids ice and fog
  • No condensation on gas lines
  • Constant gas temperature

Messer solution

Messer provides the Ecovap-evaporator for an environmentally friendly and cost-effective utilisation of the cold content of cryogenic gases.
