Fresh yeast, also known as baker’s yeast or cake yeast, is a living organism that is commonly used in baking to leaven bread and other doughs. It is highly perishable and needs to be stored properly to maintain its effectiveness.
Many bakers wonder if it is possible to freeze fresh yeast to prolong its shelf life. While freezing fresh yeast is not recommended, it is possible to freeze it under certain conditions. However, the freezing process can affect the yeast’s activity and viability, so it is important to understand the potential consequences.
When fresh yeast is frozen, the extreme cold temperature can damage the cell structure and deactivate the yeast. This can result in a loss of its leavening power and may affect the quality of baked goods. Additionally, the freezing process can cause the yeast to lose some of its moisture, which can further impact its performance.
If you find yourself with excess fresh yeast that you want to prolong the shelf life of, it is recommended to use it as soon as possible or consider alternative storage methods such as refrigeration. Refrigeration can help slow down the yeast’s activity and extend its lifespan without compromising its effectiveness.
Understanding Fresh Yeast
Fresh yeast, also known as baker’s yeast or cake yeast, is a live yeast used in baking to help dough rise. It is made from a living culture of yeast cells and is perishable, unlike dried or instant yeast. Fresh yeast is typically sold in small cakes or cubes, and its texture is soft and crumbly.
Usage
Fresh yeast is a favored choice among professional bakers because of its reliability and ability to produce a strong rise in dough. It is commonly used in bread and pastry recipes, as it provides a rich and complex flavor. Fresh yeast needs to be activated before using it in a recipe by dissolving it in warm water or milk, along with a small amount of sugar. This creates a welcoming environment for the yeast to feed on and produce carbon dioxide gas, which is what causes the dough to rise.
Storage
Due to its perishable nature, fresh yeast should be stored in the refrigerator. The ideal temperature range for storing fresh yeast is between 1°C and 5°C (34°F and 41°F). It is best to keep it well-sealed in its original packaging or stored in an airtight container to prevent moisture and other contaminants from affecting its quality. When stored properly, fresh yeast can typically last for up to two weeks in the refrigerator.
While it is possible to freeze fresh yeast, it is not recommended. Freezing fresh yeast can cause the yeast cells to die, resulting in less effective leavening power. Additionally, the texture of fresh yeast may change after freezing and thawing, affecting its ability to rise properly. It is best to use fresh yeast within its recommended storage period to ensure optimal results in baking.

Step 2: Wrap in plastic wrap
Wrap each portion of fresh yeast tightly in plastic wrap. Make sure there are no air bubbles to prevent freezer burn.
Step 3: Place in a freezer bag
Transfer the wrapped portions of fresh yeast into a freezer bag. Squeeze out any excess air before sealing the bag tightly. This will further protect the yeast from freezer burn and keep it fresh.
Step 4: Label and date the bag
Use a permanent marker to label the freezer bag with the current date and the type of yeast. This will help you keep track of its freshness and avoid confusion in the future.
Step 5: Freeze
Place the labeled freezer bag in the freezer and make sure it lies flat to save space. The yeast can be stored in the freezer for up to three months without loss of quality.
Step 6: Defrost before use
When you’re ready to use the frozen yeast, transfer the desired portion to the refrigerator and let it defrost overnight. Using frozen yeast directly in your recipes without defrosting may affect the rise and texture of your baked goods.
By following these steps, you can ensure that your fresh yeast remains fresh and effective even after freezing. Enjoy baking with the convenience of always having yeast on hand!
Thawing and Using Frozen Fresh Yeast
If you have frozen fresh yeast and need to use it, it’s essential to thaw it properly. While freezing fresh yeast can extend its lifespan, improper thawing can compromise its quality.
To thaw frozen fresh yeast, transfer it from the freezer to the refrigerator. Allow the yeast to slowly thaw in the fridge overnight or for approximately 8-12 hours. This gradual thawing process helps preserve the yeast’s activity and effectiveness.
Once the yeast is completely thawed, it’s crucial to use it immediately. Fresh yeast has a short shelf life, and freezing may slightly reduce its potency. Therefore, using it promptly will ensure the best results.
Before using the thawed fresh yeast in a recipe, test its viability. Dissolve a small amount of yeast in warm water (around 110°F or 43°C) with a pinch of sugar. If the mixture becomes frothy and bubbly within 5-10 minutes, the yeast is active and ready to use. However, if there are no signs of activity, it’s best to discard the yeast and use a new batch.
Note: Always follow the recipe’s instructions when using thawed fresh yeast. Adjustments might be necessary due to the yeast’s potentially reduced potency and freshness.
When using thawed fresh yeast, dissolve it in warm liquid (water or milk) before mixing it with other ingredients. Dissolving the yeast activates it and allows it to distribute evenly throughout the dough, ensuring proper fermentation.
Remember to store any unused portion of thawed fresh yeast in an airtight container in the refrigerator. Using it within a few days will yield the best results.
Thawing and using frozen fresh yeast correctly will help you continue enjoying the benefits of using fresh yeast in your baking, even if you don’t have access to fresh yeast all the time.
