Bluebonnet Nutrition - Super Earth Brewer's Yeast Powder - 1 lb. (454 g) Bluebonnet NutritionSuper Earth Brewer's Yeast Powder provides a select strain of Sacchromyces cerevisiae that is carefully grown on certified non-GMO sugar beet molasses instead of the typical grain-derived brewers yeast that is recovered from the beer-brewing process. Grain-derived brewers yeast tends to be particularly bitter in taste due to the nature of the grains used, such as barley and hops. Bluebonnets
