Does Freezing Yeast Ruin It?

Many foods are preserved by freezing them. This is especially helpful when you don’t want something to go bad and want to keep it to use later on. 

You can freeze yeast and save it for later. But does freezing it ruin the yeast?

Freezing yeast does not ruin it as long as you store it properly. It will still be good even after it has been frozen for months or years. 

Yeast that has been frozen is still good to use in baking.

In an article from FoodsGuy on How To Store Yeast – The Ultimate Storage Guide, they state, There has been some question as to whether freezing the yeast kills it. Freezing it does not hurt it BUT you must let it return to room temperature before activating it or using it. Yeast actually goes dormant when it is stored at below 50 degrees…Some experts would tell you that yeast can last indefinitely in the freezer…It is possible but…not guaranteed.” 

Freezing yeast doesn’t affect it at all. When you use it in upcoming weeks or months it will still have good texture and will not be ruined. To test to see if yeast is still good, you can add some warm water and a pinch of sugar to it and if it starts to bubble in a few minutes then it is still good. 

Unopened yeast will last for longer than opened. If the yeast is unopened it will last for up to 2 years in the freezer and if it is opened it will last for about 6 months frozen. 

Tightly package the yeast when you are freezing it. Use freezer bags or airtight containers to seal it so it stays good. 

Wrapping fresh yeast is important. You should use several layers of plastic wrap followed by foil to help keep yeast good.

What Is The Best Way To Freeze Yeast?

So, yeast can be stored for quite some time especially if it is unopened. This is great for bakers who like to have some on hand for wherever they are going to be making a warm and fluffy loaf of bread. 

But what is the best way to freeze yeast?

The best way to freeze yeast is to seal in an airtight container or a freezer bag. Or you can freeze it in the package it comes in as well as in an airtight wrapping. 

Unopened, the yeast will stay good in the freezer for up to 2 years and opened it will last for about 6 months.

Whether the yeast is dry or fresh, it can be frozen. Dry yeast can be frozen in its packaging, in a freezer bag, or in an airtight container for 6 months. 

Fresh yeast should be stored in an airtight way by being wrapped in layers of plastic wrap and foil and stored for 6 months as well. It is a good idea to portion out the yeast before you freeze it. 

Be sure to label the packages of yeast with the current date so you know when you put them in the freezer and when they should be used up by. Yeast should be thawed in the refrigerator overnight and it is best if you only thaw the amount you need. 

Before you use the yeast, let it return to room temperature and then use it for your recipe.

Another way to thaw the frozen yeast is mentioned in the article, Longer-Lasting Yeast: Store Dry Yeast in the Freezer from TheKitchn. They recommend that, 

You can use the yeast straight from the freezer. Sprinkling it into room temperature liquid wakes them right back up again. I’ve kept dry yeast in the freezer for months past its expiration date with no discernible change in how well the yeast works in my baked goods. I’m currently still working through a bulk bag I picked up over two years ago!…

Final Thoughts
