Saccharomyces cerevisiae typically grown on grain (usually barley) or sugarcane sap and is often the by-product of beer making. Brewer's yeast grown on sugar beets tends to be more sweet and appealing.

When grown in the presence of B₁₂ and other nutrients, brewer's yeast is used as a nutritional yeast. Others are grown with a high chromium or selenium content. In general, brewer's yeast has a wide range of nutritional values depending on the species of yeast and growth medium.

Brewer's yeast is available in powder, flake, or tablet form.
