Brewer’s Yeast

What Is Brewer’s Yeast?

Brewer’s yeast is a food supplement made from deactivated Saccharomyces cerevisiae yeast, processed into flakes or powder. It is also known as “nutritional yeast” and is usually specially grown and deactivated with heat.

The key difference from fresh or dried yeast used in bread-making is that it is not alive; it cannot leaven dough, and instead provides a cheesy, nutty flavor and a rich B-vitamin profile.

Brewer’s Yeast Nutrition

One hundred grams of brewer’s yeast contains about 325 kcal of energy; it is very high in protein and generally rich in B vitamins. Values vary by brand and are approximate.

How Should Brewer’s Yeast Be Consumed?

Brewer’s yeast is used in moderate amounts as part of a balanced diet, sprinkled over food or added to sauces.

This information is general; brewer’s yeast is a food supplement, not a medical treatment. People with a yeast allergy are advised to take care.

How to Store Brewer’s Yeast

Brewer’s yeast can be stored for months in a sealed container in a cool, dry cupboard; keeping out moisture prevents clumping.
