New lager yeast developed 1st February, 2021 by Rupert Millar
A new way of creating non-GMO lager yeast strains has been found by a bioengineering company, which it says could help “broaden the diversity of commercial lager beer strains” for big and small brewers.
The new strain has been developed by bioengineering company Renaissance BioScience in Vancouver and the paper proposes it be classified as a third group of lager strain.
Currently, as it has been for hundreds of years, there are just two yeast types from which strains can be produced: known as ‘Group I’ and ‘Group II’.
Although genetically different, they produce very similar flavour and aroma profiles, which, argues Renaissance, “play a role in the lack of diversity in commercial lager beer”.
