Yeast is a type of fungus that can be found in various forms and species. There are over 1,500 species of yeast known to science, but only a few are used in commercial baking, brewing, and other fermentation processes. Here are some of the most common types of yeast:
- Baker’s yeast: Baker’s yeast, also known as Saccharomyces cerevisiae, is the most common type of yeast used for baking bread and other baked goods.
- Brewer’s yeast: Brewer’s yeast, also known as Saccharomyces pastorianus, is used in the production of beer and other alcoholic beverages.
- Wine yeast: Wine yeast, also known as Saccharomyces ellipsoideus, is used in the production of wine and champagne.
- Wild yeast: Wild yeast, also known as sourdough starter, is a natural type of yeast found in the air and on the surfaces of fruits and grains. It is commonly used in the production of sourdough bread.
- Instant yeast: Instant yeast, also known as rapid-rise yeast or bread machine yeast, is a type of yeast that is dried and ground into small granules. It can be added directly to the dough without being activated first.
- Nutritional yeast: Nutritional yeast, also known as Saccharomyces cerevisiae, is a type of yeast that is used as a food supplement. It is a rich source of protein, vitamins, and minerals and is commonly used by vegans and vegetarians as a substitute for cheese.
These are just a few examples of the different types of yeast. Each type of yeast has unique characteristics and is used for specific purposes in the food and beverage industry.
