Phyterra's primary focus is to develop and commercialize advanced yeast technologies. Our first products are urea-degrading yeasts that reduce urea, the precursor to the well-known carcinogen Ethyl Carbamate.

Ethyl Carbamate, also known as urethane, is found in many commonly consumed yeast-fermented foods and beverages, such as wine, brandy, whiskey, sake, bread, soy sauce, sherry and beer and is a direct byproduct of the use of yeast to ferment foods and beverages.

A significant accomplishment for the company has been the acquisition of the exclusive worldwide rights to produce, market and distribute this yeast technology from the University of British Columbia (UBC). Our close association with the University enables the company to benefit from having a working association with UBC's Wine Research Centre, one of the world's most advanced wine research labs .

Phyterra’s staff are a collection of scientists, engineers and winemakers with a passion for helping you produce the highest quality, pure and natural wines.
