Webinar Summary

Diastatic yeasts are a major contamination risk to packaged beer. Brewery quality control programs rely on microbial selective methods and PCR detection of the STA1 gene, however, there is a wide functional range of diastatic activity that remains unresolved by these current methods.  This presentation will discuss novel functional assays that provide improved risk assessment of re-fermentation in packaged products with the potential for determining contaminant thresholds for different STA1+ strains and weighing in on the decision to dump beer or issue a product recall.
