How Much Yeast Is in a Packet – Good to Know!

If you do any baking, you likely are familiar with yeast. Yeast is a living organism that helps baked goods rise and become fluffy.

For instance, bread and rolls without yeast would be dense and flat.

Yeast typically comes in dry form- in packets- and is activated by adding warm water and/or sugar.

How Much Yeast is in a Packet?

Generally, there are around 2 and ¼ teaspoons- or ¼ ounce- of yeast in one packet of active dry yeast for baking. A teaspoon is often compared to a quarter of a tablespoon, so the yeast packet would contain around two quarter-tablespoons servings or portions of yeast.

Active Dry Yeast

Yeast is an important ingredient that helps make your baked goods and culinary creations rise and become beautiful.

Yeast is integral to the baking process for many recipes, including bread, rolls, and cakes.

Yeast is a leavening agent, plus it adds a distinctive flavor to your baked goods.

Typically, consumers buy yeast in packets of premeasured amounts that make it easy to use in home baking.

While this is one simple way to purchase and use yeast, you could also buy yeast in bulk, in cakes, or make your own fresh starter yeast for baking.

To be used in cooking, yeast must first be activated by adding warm water to it.

Some recipes may call for you to also add sugar to the yeast and water, which feeds and helps the yeast bloom and activate.

This activation begins a chemical process of fermentation that releases carbon dioxide and alcohol.

Another advantage of active dry yeast packets is the long shelf life.

You should know, however, that the efficacy of yeast can diminish over time or when stored improperly.

That is why it is important to always keep your yeast packets in a cool, dry place.

Also, there are some distinctions between active dry yeast and instant yeast that you should know before using them in your baking.

Active dry yeast has a larger consistency and bigger particles than instant yeast, so it needs to bloom and proof in warm water a bit longer before using.

Instant yeast, on the other hand, dissolves and activates quickly. You may be able to simply add instant yeast to the other dry ingredients without activating it at all!

Refer to your recipe for more information pertaining to using instant yeast.

Substitutes for Yeast

Yeast makes baking easy and successful, helping the dough and bread to rise and become fluffy.

Remember that each packet of active dry yeast contains around 2 (plus a little more) teaspoons of yeast, around a quarter ounce of yeast per package.

So, what can you substitute when yeast is simply not available? There are a couple of suggestions that may help!

  • To substitute yeast, try mixing baking soda and an acidic liquid like vinegar or lemon juice. Combining the two creates carbon dioxide, which will help your baked goods rise. Use equal parts soda and acid, and substitute 2 teaspoons of dry yeast for a combined 2 teaspoons of your soda/acid mixture.
  • Never run out of yeast again by making your own sourdough yeast starter! A cup of homemade sourdough starter is the equivalent of a packet of dry active yeast- and it will make some of the best bread you have ever tasted!
  • Substitute double-acting baking powder for yeast in your recipe. Replace the same amount of baking powder for yeast as the recipe calls for.
