What Is Instant Dry Yeast?

By: Bob's Red Mill | May 9 2022

For decades active dry yeast was the most popular type around. However, as the community of home bakers grows, so does the need for easy-to-use yeast. During quarantine, many things changed, and as things are slowly returning to normal, one thing remains the same. More individuals have discovered a love for baking and cooking meals at home. If you added bread making to your list of quarantine skills or have been creating great-tasting loaves for years, dry yeast is undoubtedly an essential ingredient in your kitchen. Unlike active dry yeast, instant yeast doesn't require proofing or rehydration before adding to the dough. This one-step method makes baking up a tasty loaf of bread easier than ever. Take your baking skills to the next level and continue reading to learn more about instant yeast and its many uses.

Types of Yeast

Types of Yeast

There are two main types of yeast for baking: fresh yeast and dried yeast. Fresh yeast comes in small blocks and can be found in the refrigerated section at most grocery stores. Its short shelf-life and high flavor quality make it a valued ingredient at bakeries but limited for at-home bakers. 

Most bakers turn to active dry yeast and instant yeast for yeast with a longer shelf-life. Though the two produce nearly identical results, the main difference is the size of the granules. The granules in active dry yeast are larger and require proofing before use. Instant yeast comprises much smaller granules and does not need proofing to be effective.

How to Activate Instant Yeast

If stored correctly, instant yeast should remain fresh until its expiration date and can be added directly to dry ingredients when used to create doughs and baked goods. If you're unsure whether or not your instant yeast is still fresh, it can be tested through proofing before being added to the recipe. 

How to Proof Instant Dry Yeast

Do you have a batch of instant dry yeast that you'd like to test for freshness? Proofing yeast involves combining the yeast with liquid, allowing it to sit for a while, and waiting to see if it creates a frothy, foamy top.

If, after a few minutes, foam is produced, it's a good indicator that the yeast is still alive. Follow the steps below to correctly proof instant dry yeast.


  1. In a small bowl, mix ¼ cup of the liquid called for in the recipe you're following with the amount of yeast on the ingredient list.
  2. Allow the mixture to sit at room temperature for 10-15 minutes. After 15 minutes, you should begin to see foam on the surface of the liquid.
  3. If the mixture is foaming, the yeast is still alive, and you can continue with the recipe. If, after 15 minutes, no foam has been produced, then the yeast is no longer active, and you'll need to use a new batch.

Instant Dry Yeast Frequently Asked Questions

Dairy-Free Desserts for the Holidays | Bob's Red Mill Blog

If you're new to baking with instant yeast, you may have some questions about it. To help you on your baking journey, we've rounded up a list of the most frequently asked questions and their answers.

Does Instant Yeast Require Sugar?

Instant yeast does not require sugar to work properly. However, yeast does feed off of sugar, and mixing in an extra ½ tsp of sugar or honey can help speed up the proofing process.

What if Yeast Doesn't Foam?

If the yeast does not foam after proofing, there could be a few reasons why. The most common is that the yeast has either expired or was not stored properly. If you're working with yeast that does not foam, you'll need to discard the yeast and buy a fresh batch before continuing the recipe.

Should Yeast Be Stored in the Refrigerator?

While yeast can be stored at room temperature, keeping dried yeast in the refrigerator or freezer will further ensure freshness and extend its shelf-life even longer.

Can You Use Instant Yeast in a Bread Machine?

Instant yeast is ideal when baking bread in a bread machine. To use instant dry yeast, add it to the recipe at any time, and begin to make the bread right away. However, if you're filling the bread machine beforehand and plan to make the bread hours later, we recommend adding the yeast last. Doing so will keep the yeast inactive while it's in the bread machine and cause it to activate once the ingredients have been mixed and kneaded. 

What Temperature Should the Water Be When Using Yeast?

The temperature of water used depends on the type of yeast you use. Yeast is a living organism, and water that is too hot can damage or kill it. When working with active dry yeast, warm water that is comfortable to the touch works best. Instant yeast is a little more flexible as it’s mixed directly into the dry ingredients of a recipe. When working with instant yeast, relatively hot water can be used as it will combine with the other ingredients and cool off before damaging the yeast. Coldwater can also be used when baking with yeast. Using cold water will avoid the risk of killing the yeast. However, it will also take the yeast a bit longer to activate.

How to Use Instant Yeast In Baking

Cinnamon Rolls

Unlike active dry yeast, instant yeast can be added straight into the dry ingredients of a recipe. Though you can proof it beforehand, this is not a required step, and doing so will not impact the activation process. When working with instant yeast, the yeast will become active shortly after coming in contact with the wet ingredients in the recipe.

    Is there a difference between instant yeast and instant dry yeast or is the latter just a different way of calling instant yeast? I noticed that where I live, the only yeast ever found in supermarkets is labelled Instant dry yeast. So when a recipe calls for instant yeast or dry yeast, I get confused as I haven't found yeast labelled specifically as instant or dry. Just the instant dry yeast.

    Once the dough is ready to rise. Will you ruin it if you move the bowl with the dough in it? Will that affect the rising? How long does it have to rise to double in size?

      Hi Mary Ann! Moving the bowl shouldn't affect the rise, unless there's a big change in temperature, or you drop it. The rise time will depend on the specific recipe--generally 1 to 2 hours.
