Yeast Sponge Recipe: Easy Preferment for Perfect Breads 2026

A yeast sponge is one of the most useful preferments in baking. It is made by mixing part of the flour from a recipe with water and yeast, then letting it ferment until it triples in volume. The result is a sticky, active sponge that gives breads and sweet doughs a faster second rise and a deeper, more complex flavor.

The idea is simple: you take between 20 and 50 percent of the total flour in your dough and turn it into a sponge ahead of time. That means the exact amounts of flour, water and yeast vary from recipe to recipe, and you can work them out with a simple rule of three based on how much flour you take.

You can let the sponge ferment at room temperature until it triples, which takes a few hours, or slow it down in the fridge for up to two days so the yeast develops more aroma. Either way, you end up with a sticky mass that you simply add to the final dough when you are ready to knead.

Ingredients for Yeast Sponge

This makes 1 sponge, enough to add to your chosen bread or sweet dough recipe.

• 100 g wheat flour
• 80 g water
• 3 g fresh yeast, or 1 g dry baker's yeast

How to Make Yeast Sponge Step by Step

1. Combine the ingredients

Put 100 grams of wheat flour, 80 grams of water and 3 grams of fresh yeast into a jar. If you are using dry baker's yeast, use 1 gram instead. There is no need to dissolve the yeast first; it will hydrate as you mix.

2. Mix into a sticky paste

Mix everything very well until you have a slightly sticky paste with no dry flour left. Scrape down the sides of the jar so the sponge ferments evenly.

3. Let it ferment until tripled

Leave the jar at room temperature or in the fridge until the sponge triples in volume. At room temperature this takes between 2 and several hours depending on the temperature; in the fridge it can take up to 2 days. If you ferment it in the fridge, bring it back to room temperature before using it.

4. Add it to your recipe

Once the sponge has tripled in volume, it is ready. Simply add it to the rest of the ingredients in your recipe and continue with the steps as written.

Tips for the Best Yeast Sponge

Scale it to your recipe

Use 20 to 50 percent of the total flour in your dough for the sponge. Calculate the water and yeast with a simple rule of three based on the amount of flour you take, so the sponge fits your recipe perfectly.

Choose room temperature or fridge

A warm room speeds things up and can triple the sponge in a couple of hours. A cold ferment in the fridge slows the process down but develops more aromatic yeast flavors, so pick based on your schedule.

Bring it back to room temperature

If the sponge fermented in the fridge, let it sit at room temperature before adding it to your dough. This wakes up the yeast and helps the final dough rise predictably.
