Do you have an in-house or proprietary yeast that you would like improved?

Phyterra Yeast is offering end users, wineries and breweries a new and unique service. We can cross your strain with UCD 932 (a non H2S strain) and retain the great majority of its original attributes. In fact, we can retain 90%, 95% or even more of the features of the parent strain.

Figure 1. Example of what can be accomplished

P8Y0 (left) and wild-type (right) strain streaked onto BiGGY (Bismuth Glucose Glycine Yeast agar). sulphide generated by the yeast results in pigmented colonies and colour intensity is relative to the amount of sulphide present.


Figure 2. H2S detection strips

The lead acetate test strips on the right were suspended above fermentations with both wild type (WT) and enhanced strains. Results to right are after 16 days of fermentation. The test strip that was inside the wild-type fermentation carboy (left) turned black while the strip that was inside P1Y0 bottle (right) remained white –as above the colour intensity is relative to the amount of H2S present.

This strain is able to bring out differentiated varietal aromas by bringing out the rich concentrated flavors found in varietals such as Syrah and Zinfandel, but also enhances less aromatic varietals such as Petit Syrah. A rapid clean fermenter characterized by its ability to ferment under diverse conditions, this yeast demonstrates strong fermentation kinetics while preserving fresh, fruit character.
