Yeast is a single-cell organism used in many industries.
While people have used it to make bread and beer for centuries, they now make probiotics, biofuel, and non-alcoholic drinks.
Scientists also use it in many experiments and researches.
There are four types of yeast, including brewer’s yeast, distiller’s yeast, nutritional yeast, and baker’s yeast.
This article will focus mainly on baker’s yeast as it is the most commonly used variety.
But there is one interesting fact about Nutritional yeast.
It is an excellent source of vitamins and minerals and offers many health benefits.
So, whether it is nutritional yeast or baker’s yeast, both are quite beneficial.
While yeast can work fine even after the expiry date, it can become inactive if you don’t store it correctly.
But how to keep it fresh longer? Can you freeze yeast? According to experts, yes, it is possible to freeze yeast to make it last longer.
Does Freezing Affect Yeast?
When it is about the effect of freezing on yeast, it is different for each kind.
Regarding fresh yeast, it is entirely safe to freeze it without losing its flavor and texture.
However, you should break it into small chunks to use only a required quantity when necessary.
You can also freeze-dry and active yeast without diminishing its properties.
It will remain in a first-class condition for a more extended period if you do all the steps carefully.
It is possible to freeze instant or rapid-rise yeast, but it has an extended shelf-life.
Hence, experts say there is no benefit in freezing it. Freezing can also damage its texture.
But if it becomes vital to freeze it, it is crucial to follow the freezing process carefully.
Since the three subtype yeasts have different properties, the steps to freeze them also differ.
In the sections below, we will learn how to freeze each type of yeast.
That way, no matter whatever kind of yeast you buy, have, and use, you will know how to store it.
How To Freeze Yeast?
With yeast being a handy ingredient in baking, freezing some quantity can be helpful whenever you want to bake something.
If you learn the process of freezing each type of yeast, you can store it safely when you need to.
What are the proper steps to freeze yeast? There are separate steps to freeze yeast, and we will go about it one by one.
1 – Fresh yeast.
• Whether you make yeast from scratch or have a significant quantity from the purchased batch, cut the block into large pieces.
Make the sizes suitable so that you have to defrost only the amount required at a time.
• The next step is to wrap the yeast with clingfilm or plastic.
Repeat the procedure using aluminum foil with each chunk.
• Now, you can put the wrapped chunks in a safe freezer bag.
If you don’t have a vacuum sealer, make sure to squeeze out all the air.
• Write the date and content name and tag the freezer bags.
• The process of rewrapping is to retain the moisture by taking out the air completely.
So, do the steps correctly.
2 – Dry, active yeast.
• You can store any dry and active yeast in the freezer.
Unopened packs can remain fresh for a long time, even at room temperature.
But see that the storage area is cool and dry.
• If the pack is already opened, wrap or seal it tightly and place it in the freezer.
Using freezer-safe bags will be the best option.
• The contents will last a long time, and you can use the yeast whenever you need it.
3 – Instant or rapid rise yeast.
Instant yeast has a long shelf life. But if you have some doubts after you open a pack, seal it tightly in a freezer-safe bag and put it in the freezer.
How many methods to freeze yeast? The point of freezing yeast is to lengthen its shelf-life.
There are other methods to freeze yeast, but they are not as effective as mentioned above.
How long does frozen yeast last in the freezer?
Once you put the sealed bags with yeast in the freezer, the contents can remain in top condition for up to six months.
How to Thaw Frozen Yeast?
If you love to bake, you will need yeast regularly. Hence, storing yeast will be quite convenient.
Once you have the yeast in storage, baking will be even more enjoyable.
You only have to thaw the required quantity and use it as necessary.
Defrosting yeast is accessible just as freezing it. The properties will remain the same.
However, it is vital not to let yeast thaw at room temperature if you use the fresh variety.
Let the yeast defrost for several hours overnight in the fridge.
With dry yeast, you can let it thaw at room temperature or in the fridge.
However, the quality will be better, and its shelf life will extend if you defrost it in the refrigerator.
While defrosting yeast does not damage its condition, refreezing the same is a different matter.
Most likely, it will not work as you want it to.
So, make it a point to make chunks with the fresh yeast while freezing.
You can also put the dry variety pack in several bags if you have so that you only have to thaw and use what you need.
If you have nutritional yeast and want to store it, follow the same method as the dry yeast.
You can also do the same with thawing.
Nutritional yeast offers many health benefits, as mentioned earlier.
Since it has all the nine amino acids which humans need, it is called a complete protein.
Whether you have baker’s yeast or nutritional yeast to freeze, all you need to do is follow the correct process.
Though each step for freezing and thawing is simple, one slight mistake can cause a big difference.
You can also get some tips on freezing and thawing brewer’s yeast and distiller’s yeast if you are curious to know.
Sometimes you may not have yeast at home, and your local store may run out of yeast.
During such times, you can make a homemade substitute for yeast too with a sourdough starter.
But you now know how to preserve yeast, and hopefully, you never run out of yeast.
Get some now and store it in the freezer for rainy days.
