We have received some questions as to whether White Labs WLP644 Brettanomyces bruxellensis Trois is not a strain of Brettanomyces. We obtained the original culture from a reputable source,​ ​identified ​as​ ​a species of​ ​Brettanomyces.

We have been doing experiments on this in-house and sending the strain to​ ​independent​​ ​laboratories​ for some time. When we have a definitive genetic answer we will be happy to share that information.

In addition, we have had a​​ 2-year collaborative research project​​ to completely sequence more than 96 of our yeast strains, both​ ​Brettanomyces and Saccharo​myces, which we hope to begin publishing in 2015. The complete sequencing of brewers yeast strains in this magnitude has never been done before, and we expect it will change the way many yeast strains, this​ one​ included,​​ ​are currently categorized and understood.
