When it comes to fresh brewer’s yeast, we often end up buying a package larger than what is needed for a single recipe. And then, what to do with the leftover part? We might think of putting it in the fridge, but we know that once expired, the yeast starts to lose its properties and is no longer as useful. Here’s the solution: freeze fresh brewer’s yeast. Once frozen, it can be used even after the expiration date, without wasting anything, and we can always have it handy for the next pizza, focaccia, or bread.

How to Freeze Fresh Brewer’s Yeast: Steps to Follow
The process to freeze fresh brewer’s yeast is really simple, but there are some things to keep in mind to do it in the best way possible, in order to preserve all its characteristics.
First of all, make sure the yeast is not already expired. Fresh yeast is particularly sensitive, and when it is close to expiring or expired, it loses its strength. Freezing it while it’s still fresh will ensure that, once thawed, it can rise properly.
How to use frozen brewer’s yeast? It’s really simple, take your portion or break a piece off the whole block with a knife, you just need to dissolve it in water and use it as usual. Help the yeast dissolve with your fingers, it will make the process easier.
Do not use the microwave or immerse it in hot water, you might inhibit its leavening power.
The color of brewer’s yeast is light brown and when it’s fresh it crumbles easily. When it is no longer good, it will tend to develop dark spots and become soft to the touch.

When you remove the yeast from its packaging, it is important to protect it from air. Wrap it in plastic wrap ensuring that no air gets in. Another way to do this is to use a food freezer bag. Do not neglect this step, otherwise, the yeast will risk drying out and losing effectiveness.
If you use yeast in small quantities, it is advisable to make portions. For example, I prefer to portion it into 0.1 oz (3g) for smaller preparations and 0.9 oz (25g) for larger ones. If you freeze a whole block, once it’s frozen it becomes very hard, and it will be difficult to take a part without risking warming it a bit with your hands or with a knife. So, before freezing it, cut it into practical portions that you will need for your daily recipes.
After wrapping and portioning it, place the yeast in the freezer. The freezing time is really short: about an hour, and it’s ready to be stored for a long time. To keep track of how long it has been, you can write the freezing date on the bag with simple tape.
How to Use Frozen Brewer’s Yeast
Now that the yeast is ready to be used, you no longer have to worry about always having fresh yeast at home. But how to use it best?
Don’t use the microwave!: When you need frozen yeast, don’t heat it in the microwave or immerse it in too hot water. These methods may inhibit its ability to rise. The secret is to dissolve it in lukewarm water and, if necessary, help it a bit with your hands. This thawing method will ensure that the yeast maintains its efficiency.
Use it as usual: Once dissolved, you can add the dissolved yeast to your recipe, just as you would with fresh yeast. And you’re done!
How Long Can I Store Frozen Yeast?
The shelf life of frozen yeast is about 1 month, but it can still be good even a few days beyond the expiration date, thanks to freezing which slows down its degradation. If you see that the yeast has started to become too soft or has dark spots, unfortunately, it will no longer be usable. In these cases, it’s better to avoid using it, to not compromise the success of your recipes.
Variations and Tips
Don’t have fresh brewer’s yeast? You can use dry yeast instead, even though it doesn’t need to be frozen.
Practical portioning: Freezing yeast in portions saves you time and allows you to use only the amount you need, avoiding waste.
