### More About Omega Yeast DKO Strains:
Omega's DKO series maintains the same fermentation behaviors and flavor as parental strains but prevents diacetyl formation. ALDC in these strains stops diacetyl production at the source.
### What is ALDC
ALDC breaks down the diacetyl precursor into a flavorless compound. When expressed in DKO strains, it prevents diacetyl from entering the beer.
Available only in the US due to international regulations on gene - edited organisms.
