Nutritional Yeast vs Baker’s Yeast vs Brewer’s Yeast

Nutritional, baker’s and brewer’s yeast can all use the same species of yeast. Brewers may use different yeasts depending on the type of beer being made, but Saccharomyces cerevisiae is a popular solution.

  • Brewer’s yeast: Brewer’s yeast can be used for both the creation of beer and as a nutritional supplement. The dead cells from brewing remain after the process is complete. They add a bitter taste, but are unpalatable when eaten on their own.
  • Nutritional yeast: Nutritional yeast is used solely as a food product. The yeast cells are killed during manufacturing and will not be alive in the final product. It is used to add cheesy, nutty, and savory flavours.
