How to Make Yeast for Long Term Storage


Yeast is an essential ingredient in baking bread, making beer, and even fermenting vegetables. It’s an incredibly versatile and important component in many recipes. However, yeast can be quite perishable, and it may not always be readily available, especially in a long-term survival situation. That’s why it’s crucial to learn how to make yeast for long term storage. In this article, we will explore different methods to produce yeast that can be stored for an extended period, ensuring you can continue baking and fermenting even when traditional sources of yeast are scarce.

The Importance of Yeast in Food Production

Before we dive into the methods of making yeast for long term storage, it’s crucial to understand why yeast is crucial in food production. Yeast is a microorganism that plays a significant role in fermentation. When added to dough, it converts sugars into carbon dioxide gas and alcohol, leading to the rising of bread and the development of unique flavors in beer and other fermented foods.

The Many Uses of Yeast

Yeast has a multitude of uses in the culinary world and beyond. Here are a few of the main applications:

– Bread making: Yeast is responsible for the leavening that makes bread rise, giving it a light and airy texture.
– Beer brewing: Yeast is an integral part of the beer-making process, as it ferments the sugars and produces alcohol.
– Wine making: Similar to beer brewing, yeast is used to ferment the sugars present in grape juice and turn them into alcohol.
– Fermenting vegetables: Yeast is used in the process of lacto-fermentation, where it helps create the perfect environment for beneficial bacteria to thrive, resulting in foods like sauerkraut and kimchi.

Methods for Making Yeast for Long Term Storage

Now that we understand the significance of yeast, let’s explore some methods for producing and storing yeast for the long term.

Method 1: Capturing Wild Yeast

One of the simplest ways to make yeast for long term storage is by capturing wild yeast from the environment. Here’s how you can do it:

1. Mix equal parts flour and water (by weight) in a bowl to create a paste-like consistency.
2. Leave the mixture uncovered in a warm place, ideally around 70°F to 75°F (21°C to 24°C).
3. Stir the mixture once or twice a day for about a week, adding a little more flour and water each time to maintain the consistency.
4. After a week, you should notice bubbles forming and a slightly sour smell, indicating the presence of yeast.
5. Transfer a small amount of this mixture into a sterile jar and store it in the refrigerator for long term storage.

Method 2: Potato Yeast Starter

Another method for making yeast for long term storage is by using potatoes. Yes, that’s right, potatoes! Here’s how to do it:

1. Boil two medium-sized potatoes until they are soft and easily mashed.
2. Drain the water used for boiling the potatoes into a clean jar. Allow it to cool to room temperature.
3. Mash the boiled potatoes and add them to the jar of potato water. Mix well.
4. Add a tablespoon of sugar to the mixture and stir until dissolved.
5. Cover the jar with a cloth or coffee filter secured with a rubber band to allow airflow while preventing dust and insects from getting in.
6. Place the jar in a warm spot for 24 hours.
7. After 24 hours, you should see some bubbling in the mixture, indicating the presence of yeast.
8. Transfer a small amount of this mixture into a sterile jar and store it in the refrigerator for long term storage.

Method 3: Purchase Dry Yeast for Long Term Storage

If you prefer a more reliable and convenient option, you can also purchase dry yeast for long term storage. Dry yeast typically comes in packets or jars and has a much longer shelf life than fresh yeast. When stored in a cool, dry place, such as a pantry or root cellar, dry yeast can last for years, making it an excellent option for prepping and survival situations.

Storing Yeast for the Long Term

Regardless of the method you choose for making yeast, it’s essential to store it properly for long term use. Here are some tips for storing yeast:

– Use clean and sterile jars or containers to prevent the growth of unwanted bacteria or molds.
– Label the jars with the date of preparation to keep track of freshness.
– Store the yeast containers in the refrigerator or another cool, dark place to extend their shelf life.
– Consider a vacuum sealer or oxygen absorbers to remove air and further help preserve the yeast.

My 2 Cents

Learning how to make yeast for long term storage is an invaluable skill for any survivalist or prepper. By capturing wild yeast or using other methods, you can ensure a constant supply of yeast even in challenging situations. Remember to practice and experiment with these methods ahead of time to hone your skills and guarantee success when it truly matters. So go ahead, start experimenting, and enjoy the taste of freshly baked bread, homemade beer, or tangy fermented veggies, no matter the circumstances!
