Frequently Asked Questions

Why do flours absorb differently?â–¼

Flours with more bran (like Whole Wheat) or higher protein (like Bread Flour) absorb more water. Bran acts like a sponge, soaking up liquid that would otherwise hydrate the gluten.

What is "hydration percentage"?â–¼

It's the ratio of water weight to flour weight. For example, 75g water / 100g flour = 75% hydration. This calculator adjusts that ratio to maintain the same dough feel.

Does humidity affect this?â–¼

Yes! In humid environments, flour absorbs moisture from the air, so you might need slightly less liquid than calculated. Always hold back a splash of water and add it only if needed.
