IMPBW113 – Control temperature reduction in brewing

 

Overview 

This standard covers the skills and knowledge needed for you to control temperature reduction in brewing.

This standard details the skills required to removing heat to achieve the required change in the condition of the product or to preserve the product state and/or quality. It details the skills required to start up, run and shut down equipment, as well as being able to take the appropriate action should operating problems occur. It is also about working to product specifications and production schedules. Complying with and understanding health and safety, food safety and organisational requirements are essential features of this standard.

This standard also covers understanding the principles of warm maturation and cooling for beers intended as cask beers in brewing, understanding the principles of maturation and chilling for beers intended as chilled and filtered beers in brewing and understanding the principles of chilling and carbonation/nitrogenation of beers intended as chilled and filtered beers in brewing.

This standard is for you if you carry out operative tasks which involve controlling temperature of cask beers, chilled or filtered beers or if you are involved in the carbonation/nitorgenation of chilled and filtered beers.
