3 Simple Ways To Make Your Yeast At Home

Since many of you are aware that learning to cook from scratch is an essential survival skill, you may have also tried creating your own amazingly tasty bread. Keeping active yeast on hand is a drawback of long-term planning and breadmaking. Yeast has an average "best by" date of two years. It needs to be kept dry and cool after being opened. Yeast can last up to 4 months in a refrigerator and 6 months in a freezer before going bad. Older yeast has occasionally worked well for some people, but generally speaking, store-bought yeast should only be used temporarily. 

Although the procedure for creating yeast involves a number of intricately detailed processes, tools, and chemicals, it is actually quite simple and easy to learn. A few simple kitchen utensils and common household objects can be used to culture yeast at home. Once you have everything you need, you may start to create your own yeast, which will take some time and careful attention. However, once you master the procedure, you'll be able to create your own yeast whenever you require it, such as for baking your own bread, brewing your own beer, or creating other delectable cooked or baked foods that require yeast. Here’s How to make your own yeast at home.  

Yeast From Fruit 


Clean Glass jar.  (24oz. or larger) Sterilize in hot water and allow it to dry. 

Water. Clean, filtered, or bottled is good. (too much chlorine in your water, or water that is too basic, can kill the yeast) 

Raisins or other fruit. Most fruits have traces of yeast on their skins. Note that you may not get as good of a result with fruit that has been washed and waxed. 


In your jar, add three to four tablespoons of raisins. A few teaspoons of sugar or honey can be added to speed up the fermentation process. 

The jar should be 3/4 full of water. Lightly screw the top onto the jar. You need to let some air out, therefore don't tighten the lid. 

Set the jar in a space with a consistent temperature. The jar must not become chilly. By doing so, the process will be stopped and the yeast eliminated. 

For three to four days, stir at least once every day. Yeast is present when the liquid starts to bubble up on top and you can smell a wine-like fermentation. The fruit, or raisins, should float. Your new yeast should be put in the fridge. 

Yeast From Grain 


1 ¼ cup unbleached all-purpose flour or milled wheat berries 

1 cup clean warm water 

1 sterile jar with cheesecloth or lid 


Stir together the flour and warm water, then refrigerate the mixture. The combination will start to bubble and rise after a few days. If not in use, keep your starting in the fridge. Use this sourdough starter just like any other. 

Yeast From Potatoes 


1 unpeeled medium-sized potato 

4 cup warm water 

1 tsp salt 

1 tsp sugar 

1-quart jar 


To get rid of dirt, rinse your potato, but don't scrub it vigorously. To make it easier to cook, cut it into pieces and boil it thoroughly. Drain the water and keep it. Salt and sugar are added to the mashed potato. Cool the mixture until it reaches room temperature. To make the potato mash into a quart-sized mixture, keep adding water. It should ferment for a few days under cover in a warm environment. 

Feed The Starter 

Once you have produced your own yeast, you must regularly "feed" it. To allow the yeast to continue to thrive, add 1 cup of flour and 1 cup of water to the mixture. If the starting is kept at room temperature, you must feed it every day; if it is kept chilled, you must feed it every week. 

In order to maintain the ratios if you don't bake bread that day, you will also need to discard one cup of the starter after feeding. This is a crucial step that can inspire you to bake frequently so that none of your efforts are wasted.
