Can You Refreeze Yeast? Here’s Why You Shouldn’t

Can You Refreeze Yeast

Your family might not get over the hand-baked bread you made last time. Its rich softness stole the show, all thanks to yeast. But, it can get troublesome to store and handle your magical ingredient at home.

Refreezing can raise many doubts as you do not want to kill the healthy fermentation agent. However, if you go for it, will the yeast still fluff the bread just like normal?

You cannot refreeze yeast, and it is not advisable to do so. Freezing it again might kill the yeast cells and decrease its rising property. Use fresh yeast as soon as possible as it perishes early. Instant dry has a longer shelf life and remains good if handled rightly. Frequent temperature changes can work against the yeast, and it will not activate fully.

If you are cautious, yeast can survive for an extended period without losing its potential. You can adopt some safety precautions highlighted in this article for effective results.

Is It Safe To Refreeze Yeast?

If you try baking often, you must be well aware of the great benefits of yeast. It helps in raising the bread and gives it a fluffy texture. Since bread is a staple food product, we require yeast in our kitchen all the time.

Freezing yeast might sound like a preferable option to make it shelf-lasting. Nevertheless, you might get away with one-time freezing, but doing it again is never recommended. A significant portion of the culture in the yeast can die due to refreezing. As a result, it might not activate after thawing and is of no use anymore.

As yeast is a living thing, it is prone to perish rapidly. The harsh freezer environment can act as an enemy against it and decrease the overall potential of the yeast. It can instantly dry out, resulting in killing the yeast. Thus, even if you use it in the future, you will get no raise in the bread.

However, if you utilize your frozen fresh yeast in making bread, you can proceed with the refreezing process. Refreezing the yeast directly is not ideal. But, it can survive well once mixed up with the dough.

Fresh yeast

When you freeze fresh yeast for the first time, it tends to lose many of its properties. Thus, it is no longer suitable to withstand another cycle of freezing and thawing. The elasticity of the yeast changes during the freezing process and goes to sleep.

When you freeze it more than once, it will result in many yeast cells dying and make it unfit for your baking. So, it is better to utilize the yeast after initial freezing and not leave it for future storage in the freezer.

Instant dry yeast

Instant dry yeast has a longer shelf life as compared to fresh yeast. Freezing puts it in a state of suspension, and once you thaw it, it comes back to life. Refreezing might kill many yeast cells along the way, and you do not want that.

You can, instead, divide the yeast into separate batches according to the quantity you generally use. It will help in cutting down the pain of constant freezing and thawing. However, avoid keeping your instant yeast for too long inside the freezer. Also, always store it in airtight containers to minimize the chances of air contamination.

Can You Refreeze Yeast Dough/Bread?

While freezing yeast alone is not a suitable option, you can store it when paired with dough or bread. As the yeast is activated and the dough has risen, it will be safe to pop it back in the freezer. But still, you might notice some changes in the overall texture of the dough after refreezing.

The dough becomes much harder because of the repeated thawing and defrosting process. It loses some moisture and elasticity that the dough possesses while making it. As an outcome, when you finally use it to create a bread loaf or pizza crust, the changes become more apparent.

Despite the quality loss, it is safe to consume, and you can share the delicious end products with your family and friends. But, if you are looking for the original fluffiness of the yeast bread, refreezing might not work for you.

Easy Method To Avoid Refreezing Yeast

While refreezing your yeast is not advisable, you can go for another alternative to keep it in a good state. Once you open the yeast packaging, it needs placement in a secure environment. It is perishable when exposed to air and room temperature for longer durations.

As freezing can be a savior for your yeast, refreezing may work as the exact opposite. You can avoid it easily by breaking your yeast into manageable chunks while freezing it for the first time.

  • Once you separate, wrap the individual batches multiple times in a plastic wrap to protect the yeast.
  • Afterward, transfer it into a sealable freezer bag or airtight container.
  • Ensure to label the bag with the date to know how long it has been in the freezer.
  • Lastly, store your yeast in the coldest part of the freezer for as long as you prefer.
  • You can now take only the amount you require without exposing the remaining quantity to air and defrosting it again.

Note: try to utilize the yeast sooner and not leave it inside the freezer for long. If it stays in the cold environment for an extended period, the yeast might lose its rising properties.

Thawing Frozen Yeast; Here’s How

If you possess dry yeast, you do not have to thaw it first. You can use it straight from the freezer.

In the case of fresh yeast, you must thaw it overnight in the refrigerator. Never defrost it at room temperature as it can spoil the yeast. Make sure to keep it covered to prevent drying it out. The thawing span can be more or less depending upon the quantity of the yeast. Usually, a large amount can take around 12 hours to thaw evenly.

You can also opt for microwaving technique if you have frozen yeast dough. Lightly grease the dough with oil and cover it in the microwave-safe wrap. Then, place it on a microwave-friendly plate and heat it for about 3-4 minutes. The high temperature will reactivate the yeast.


Yeast cannot survive refreezing and ultimately turns useless. If you do not want to waste it away, you should drop the idea of freezing it after you thaw it. Portion freezing can be the second option if you need to store it until the desired time.

Fresh yeast generally perish early compared to dry yeast, so you should utilize it quicker. Also, never leave it in the open environment for too long after thawing. Prolonged exposure to air can act as the worst enemy of yeast and slow down its rising ability.

No doubt, it has many benefits and is always required in the kitchen. By implementing a few steps in your routine, you can significantly extend its shelf life.
