Industrial Propagation

To ensure purity of strain , a 'clean' sample of the Yeast is stored in a laboratory environment at refridgerated temperature. After a certain number of fermentation cycles , a full scale propagation is produced from this laboratory sample. Typically, it is grown up in about 3-4 stages using sterile Brewing wort and oxygen / air.
