Yeast Calculator

Calculate the right amount of yeast for your bread based on flour amount, yeast type, and desired rising time. The calculator automatically adjusts the yeast quantity for perfect rising.

Fresh yeast vs. dry yeast

Fresh yeast is sold in blocks and must be stored cold. Dry yeast is more concentrated and has a longer shelf life. As a rule of thumb, use about one third dry yeast compared to fresh yeast. 25 g fresh yeast equals about 8 g dry yeast.

Rising time and yeast amount

The longer the rising time you want, the less yeast you need. Long rising time gives more complex flavor and better bread structure. For a quick 1-2 hour rise, use the standard amount, while a 24-hour cold rise needs only about 10%.

Tips for good rising

Temperature plays a big role. At room temperature (20-24ยฐC) dough rises normally. In the fridge (4-6ยฐC) it rises slowly over many hours. Avoid temperatures above 40ยฐC as this can kill the yeast.

Frequently Asked Questions

How much yeast should I use for 500 g flour?

For a standard 1-2 hour rise, use about 25 g fresh yeast or about 8 g dry yeast. For longer rises, reduce the amount. For a 24-hour cold rise, use only about 2.5 g fresh yeast or under 1 g dry yeast.

Can I convert from fresh yeast to dry yeast?

Yes, divide the amount of fresh yeast by 3 to get the dry yeast amount. 25 g fresh yeast = about 8 g dry yeast. Dry yeast can be added directly to flour, while fresh yeast is typically dissolved in lukewarm water first.

What happens if I use too much yeast?

Too much yeast gives bread an unpleasant yeasty taste and can make the dough too airy and unstable. The bread may also collapse during baking. It's better to use less yeast and give the dough more time to rise โ€“ this gives better flavor and structure.
