A new genetically modified yeast variety designed for use in wine production has been found to behave similarly to the parent commercial yeast strains during fermentation, according to its manufacturer First Venture Technologies. [...] First Venture Technologies’ propriety yeast claims to be able to reduce levels of the carcinogen ethyl carbamate, a compound that can naturally occur in fermented foods and beverages, such as wine, beer and bread. The firm says its yeast can reduce levels of the substance in red wine by up to 89 percent, and in bread by up to 54 percent.
