IMPBW110 – Control yeast cropping and storage in brewing

 

Overview 

This standard is about the skills and knowledge needed for you to control yeast cropping and storage in brewing. 

This standard details the skills and understanding required to crop (harvest) and store yeast so that it is available to pitch (add to) cooled, oxygenated hopped wort. It details the skills required to initiate, run, monitor and complete the process as well being able to take appropriate action should operating problems occur. It is also about working to product specifications, production schedules and, standard operating procedures in the fermentation area of the brewery.  

This standard is for you if you carry out operative tasks which involve the cultivation and production of yeast in brewing.
