How to Make Yeast for Long-Term Storage


Yeast is a crucial ingredient in baking as it serves as a leavening agent, helping your bread and other baked goods rise. It can be challenging to store yeast for an extended period, especially in emergency situations when traditional sources may not be readily available. However, with a little know-how, it is possible to make and store your own yeast for long-term use. In this article, we will explore different methods of making yeast and share some tips on how to store it properly.

Method #1: The Potato Method

One of the most straightforward and effective ways to make yeast is by using potatoes. Here’s what you’ll need:
– 1 medium-sized potato
– 1 tablespoon of sugar
– 1 cup of water

Begin by peeling and dicing the potato into small pieces. Boil the potato in water until it becomes soft and mashable. Remove the potato pieces from the water and mash them thoroughly. Add sugar to the mashed potatoes, and mix well. Allow the mixture to cool down to room temperature.

Once the mixture has cooled, add yeast to the mixture, stirring it in gently. Cover the container with a clean cloth and place it in a warm area, undisturbed, for 24 hours. After 24 hours, you should see some foaming and bubbling, which indicates that the yeast is active and ready to use.

Method #2: The Fruit Method

If you don’t have potatoes on hand, you can also make yeast using fruits. Here’s what you’ll need:
– 1 cup of fruit (such as grapes, raisins, or apples)
– 1 tablespoon of sugar
– 1 cup of water

Start by crushing the fruit to release its natural sugars. You can use a blender or simply mash the fruit with a fork. Place the mashed fruit in a clean container and add sugar and water. Mix well to dissolve the sugar.

Cover the container with a clean cloth and leave it in a warm place for 3-4 days. Stir the mixture a few times each day to help aerate it. After a few days, you should start seeing some bubbles and fermentation activity. Once this happens, your homemade yeast is ready to be used.

Tips for Storing Yeast

Now that you have successfully made your yeast, it’s essential to store it properly for long-term use. Here are some tips to keep in mind:

1. Refrigeration

Once your yeast has fermented and you have finished using the initial amount, you can store the remaining yeast in the refrigerator. Transfer it to a clean, airtight container and place it in the refrigerator. Refrigeration slows down the yeast’s activity, prolonging its shelf life.

2. Freezing

If you want to store yeast for an even longer period, freezing is an excellent option. Transfer your yeast to an airtight container and place it in the freezer. Freezing suspends the yeast’s activity, allowing it to remain viable for several months or even years. When you need to use the yeast, simply thaw it in the refrigerator overnight before using it.

3. Dehydration

Another way to store yeast long-term is by dehydrating it. Spread your freshly made yeast thinly on a baking sheet or parchment paper and leave it to dry in a cool, dry place. Once it is fully dry, crumble it into a powder and store it in an airtight container. Dehydrated yeast can remain viable for an extended period, as long as it is kept away from moisture.

My 2 Cents

Knowing how to make yeast for long-term storage is a valuable skill, especially for preppers and those interested in self-sufficiency. By following the potato or fruit method and storing your yeast correctly, you can ensure a steady supply of yeast even in emergency situations. Experiment with different methods and find the one that works best for you. Remember, practice makes perfect, so don’t be discouraged if your first batch doesn’t turn out as expected. With time and patience, you’ll have a valuable skill under your belt and delicious homemade baked goods on your table.
