What Is the Difference Between Active Dry Yeast and Brewers Yeast?

Active dry yeast and brewers yeast are the two main types of yeast used in cookery, one for beer aficionados and the other for bakers.

Which one is for what, then?

Both have a similar strain, but there are a few major differences that you should be aware of before taking either! Otherwise, you may wind up with beer instead of bread dough! We’re simply kidding (or not), so let’s spill the tea (or beer) and discover their differences.

Difference Between Active Dry Yeast and Brewer’s Yeast

The primary distinction between active dry yeast and brewers yeast is their application: active dry yeast is used in the production of bread, whilst brewers yeast is utilized in the production of beer and wine.

Let us first study the nature of yeast in order to better appreciate their function. Yeast is a fungus-like microbial organism that excretes alcohol and carbon dioxide. Active dry yeast and brewers yeast are both derived from the single-celled fungus Saccharomyces cerevisiae.

Active dry yeast has a high carbon dioxide level but a low alcohol content. Carbon dioxide is activated by the starch component of wheat and aids in the rise of bread dough. The alcohol evaporates throughout the baking process. Without active dry yeast, baked foods would lack the frothy and airy quality that we all like.

Brewer’s yeast produces substantially more alcohol and carbon dioxide. Both are required for making a beverage alcoholic by converting the grains’ sugars into alcohol.

Brewers yeast, being a slow-rising yeast, requires plenty of time to develop and produce the required quantity of alcohol. Brewers yeast produces bubbles throughout the fermentation process. The fermentation process is complete when the surface of the beverage-in-progress is bubble-free. Wine typically takes three weeks to ferment while beer takes around two weeks.

What Do They Taste Like?

Active dry yeast has a nutty, wheat-like taste. When utilized in appropriate proportions in baked items, the yeasty taste is light and imperceptible. If active dry yeast is used during fermentation, the beer will have a very mild and unpleasant taste.

Brewers yeast, on the other hand, produces an extremely bitter taste that is the signature flavor of beers. When brewing yeast is utilized in baking, it produces bitter bread. Some individuals, however, may find the taste tolerable.

However, if used in cakes or cookies, brewers yeast would undoubtedly ruin your dish. To disguise the bitterness, cooks recommend adding extra sweet ingredients such as honey or simple syrup.

What Is Their Shelf Life?

The shelf life of active dry yeast and brewers yeast starts as soon as they are manufactured and packaged for commercial usage.

Active dry yeast goes through a drying process, which leads to a longer shelf life. Unopened dried yeast will generally remain active for around two years. Dry yeast will keep four months in the refrigerator and six months in the freezer once opened.

Because it includes more moisture, brewers yeast does not survive as long as active dry yeast. Fresh brewers yeast must be stored in the refrigerator and will only last 6 to 10 days.

What Are Their Varieties?

There is just one kind of active dry yeast and no others. Brewers yeast, on the other hand, comes in two varieties:

  • Ale yeast is also known as top-fermenting yeast because it rises to the top of the fermentation process. This yeast ferments between 10 and 25 degrees Celsius (50 and 77 degrees Fahrenheit), most often between 18 and 22 degrees Celsius (64 and 71 degrees Fahrenheit).
  • Lager yeast is also known as bottom-fermenting yeast because it ferments towards the bottom of the fermenter. Lager yeast performs better in colder conditions than ale yeast, frequently at temperatures ranging from 7 to 15 degrees Celsius (44 to 59 degrees Fahrenheit).

Active Dry Yeast vs Brewers Yeast Comparison Table

Category Active Dry Yeast Brewer’s Yeast
Type of strain Saccharomyces cerevisiae single-celled fungus Saccharomyces cerevisiae single-celled fungus
Byproducts High levels of Carbon dioxide and low levels of alcohol High levels of both Carbon dioxide and alcohol
Type Fast-acting Slow-acting
Uses For making bread For fermenting beer or wine

Moisture content Low moisture content High moisture content
Shelf life Unopened: 2 years Opened & refrigerated: 4 months Opened & frozen: 6 months 6 to 10 days in the fridge
Varieties No varieties Ale “top-fermenting” yeast Lager “bottom-fermenting” yeast

Nutritional Content Breakdown: Which One Is Healthier?

As seen in the nutritional data below, brewers yeast is significantly healthier than active dry yeast. It has less calories, carbs, fat, and salt. It also has more calcium and iron than active dry yeast. Active dry yeast is preferable to brewers yeast solely in terms of fiber and sugar content.

Brewers yeast is a potent nutritional supplement that has been utilized throughout history in addition to being used to manufacture alcoholic drinks! It benefits every area of our body, including the nervous system, skin, hair, and eyes. It keeps one’s weight under control and their energy levels up.

Diabetes patients should take it since it helps decrease cholesterol and blood sugar levels. This vitamin is also beneficial to the liver.

Can I Substitute Active Dry Yeast for Brewers Yeast and Vice Versa?

Yes, active dry yeast may be substituted for brewers yeast and vice versa. Simply replace them with the proper amount.

Let’s begin with baking. To begin, use ale brewers yeast since other kinds (such as lager yeast) take too long to create carbon dioxide.

2 oz of active dry yeast, replace 1 oz of brewers yeast.Because active dry yeast is more strong, you must use more brewers yeast to get the same results. As an example, for 1

When baking using brewers yeast, you must also consider the taste. Brewers yeast has a strong flavor, so your bread or other baked items will taste bitter.

Making beer using active dry yeast would not give it the distinctive taste we all love since active dry yeast is not as bitter as brewers yeast.

In terms of proportions, you’ll need around 11g of baker’s yeast every 5 gal (23l) drum fermenter. Bread yeast normally ferments beer with an alcohol concentration of 8% to 10%.


This concludes our chapter on yeast varieties!

Saccharomyces cerevisiae is found to be the parent of both brewers yeast and active dry yeast. Brewers yeast is often used to make alcohol, while active dry yeast is utilized to make bread dough.

Both have nutritional properties, but only brewers yeast is utilized as a super-nutritious natural supplement!

Although you may use both interchangeably, keep in mind that the ratio may need to be adjusted to get the same results!

But which one is best for you? We really hope that this article has assisted you in better understanding your intended culinary aim!
