Strain Information

Information
Mixed culture composed of two closely related strain variants: Majority component strain 'Type 2' accessioned as a separate isolate designated NCYC 4046. Minority component strain 'Type 1' accessioned as a separate isolate designated NCYC 4047. Reported as behaving quite like a lager yeast in practice and produces somewhat of a sulphur aroma during fermentation which often persists into the final beer.
