3.5.2 - Yeast Characterisation by Fermentation in EBC Tall Tubes

This technique allows the prediction and evaluation of the stability of brewing characteristics in a strain of yeast, and also permits the study of the influence of certain technological parameters on its behaviour in fermenter. It can also be used to assess the characteristics of newly isolated yeast cultures. Descriptors: yeast characterisation by fermentation in EBC Tall Tubes.
