SOURDOUGH: What happens if you want to replace brewer's yeast with sourdough?

If you want to replace brewer's yeast with sourdough in your bread preparations, there is no problem with the working methods.

The proportion is 1 gram of fresh brewer's yeast to 10 grams of sourdough. Therefore, considering an average dosage of 30 grams of fresh brewer's yeast per kilogram of flour, the alternative or substitute solution would be 250-300 grams of sourdough per 1 kg of flour, while adjusting the amount of water to achieve the desired consistency.

However, the rising times will change significantly, as they will lengthen considerably, depending on the maturation and strength of your sourdough.
