This section is only here to explain Brewer’s Yeast.
Lesaffre Yeast Corporation does not sell “Brewer’s Yeast”. Alternatively we produce RED STAR® Nutritional Yeast, a primary grown product from pure strains of Saccharomyces cerevisiae. See our Nutritional Yeast section, or visit our Lesaffre Human Care site to learn more about our Nutritional Yeast products.
Brewer’s yeast is a by-product of the brewing industry. After 5-10 succeeding beer fermentations, the yeast, due to increasing contamination, loses its viability and activity and is no longer acceptable for making beer. The yeast then becomes surplus and can be used for the production of food flavors, feed formulations or as nutritional yeast food. Brewer’s Yeast is a dried, inactive yeast that has no fermenting power. It is sold for its nutritional qualities as it is very high in at least 10 separate B-vitamin factors.
