How does yeast multiply

Propagate yeast | Make yeast yourself

How you can propagate yeast, or how you make yeast yourself - these are topics that you read a lot at the moment. To be honest, it really upsets me when, during this time of the corona virus, I cannot buy yeast in normal retail stores for weeks because it has been tampered with and is being sold on eBay at completely absurd prices. Since Easter is just around the corner and we all want to bake something, I'm sure you have a problem similar to mine. So today I'm going to show you how to propagate yeast and how to freeze yeast.

What is yeast

Yeast is a popular baking ingredient - whether for pizza, bread or rolls. The term yeast covers various types of fungi - yeast fungi.
On the one hand there are various sugar yeasts and on the other hand so-called baker's yeast, which is used in bread or beer production.

How do you make yeast yourself?

Making yeast yourself when you don't have any more yeast at home is actually pretty easy. My kitchen chaotic shows you that on her blog - she makes yeast water herself.

How do you propagate yeast?

In this blog post we turn to a different but related topic.
If you still have some yeast at home and you can already see that the yeast will not be sufficient for baking, for example at Easter, but you still do not want to do without baking, you can simply multiply this yeast and then freeze it.

How strong is the driving force after reproduction?

How strong the driving force of the newly propagated yeast is cannot be said in general terms. You have to try it out. For example, if your recipe says "Let the dough rise for about 2 hours until it has doubled", then forget about the time factor. After two hours, look into the dough bowl - if the dough has doubled in this time, then everything is good. If it has not doubled, does it still need time, then give it more time. After all, good things take time. Here this saying applies very well. Doughs that rise longer are more digestible, more digestible and also taste better.

Thats how it works:


  • 1/2 yeast cube, fresh
  • 100g wheat or spelled flour (I used 405 wheat flour)
  • 15g sugar
  • 100ml lukewarm water


  1. Put the flour in a bowl and crumble the yeast cube.
  2. Add the sugar and the lukewarm water and mix everything well with a spoon.
  3. Cover the yeast and flour mixture and place it in a consistently warm place at room temperature.
  4. After 5-6 hours, place the mixture on cling film and roll into a sausage shape. Alternatively, they can also be portioned in ice cube containers.
  5. Place the yeast sausage roll in the freezer and freeze.
  6. From this roll you get 5 pieces of new yeast.

I wish you a lot of fun growing yeast and making yeast yourself and may you never run out of this baking ingredient.
