Bioreal provides the same reliable and excellent performance as conventional yeast yet it’s processed without chemicals and is non-GMO. Conventional yeast production uses harsh acids, bases (like lye, also known as sodium hydroxide), synthetic vitamins, ammonia and ammonium salts, and anti-foaming agents. With organic yeast production, all the raw materials used are 100% organic, benefiting the entire organic supply chain. Bioreal organic yeast is widely regarded as being superior in flavor to conventional yeast, bringing a heartier taste. 5 x 9g sachets
