What is baker's percentage and how do I calculate it?

Baker's percentage (also called baker's math) expresses each ingredient as a percentage of total flour weight. Flour is always 100%, and other ingredients are calculated relative to it. For example, if a recipe has 1000g flour and 650g water, the hydration is 65%. Flourwise automatically calculates baker's percentages for all your bread, sourdough, and pizza recipes.

How do I calculate sourdough hydration?

Sourdough hydration is calculated by dividing the total water weight by the total flour weight and multiplying by 100. This includes water and flour from your sourdough starter. For example, 70% hydration means 700g water per 1000g flour. Flourwise's sourdough calculator handles this automatically, including the water content in preferments like poolish, biga, and sourdough starter.

How often should I feed my sourdough starter?

A healthy sourdough starter should be fed every 12-24 hours when kept at room temperature, or once a week if stored in the refrigerator. The typical feeding ratio is 1:1:1 (starter:flour:water). Flourwise includes a sourdough starter feeding schedule planner to help you track and never miss a feeding.

What is a preferment and what types are there?

A preferment is a portion of dough prepared before the final mix to develop flavor and improve texture. Common types include: Poolish (equal parts flour and water with a small amount of yeast), Biga (Italian preferment with less water, around 50-60% hydration), and Sourdough Starter (natural levain using wild yeast). Flourwise supports all these preferments with customizable hydration levels.

How do I convert a recipe to baker's percentage?

To convert a recipe to baker's percentage: 1) Identify total flour weight as your base (100%), 2) Divide each ingredient's weight by the flour weight, 3) Multiply by 100 to get the percentage. Flourwise does this automatically - simply enter your ingredients and the app calculates all percentages instantly, making it easy to scale recipes up or down.
