Choosing a sourdough flour

Sourdough ferments slowly, so the flour needs enough strength to last the whole rise. Most of the flours here are Strong or Very strong, W 300 and up.

Grain matters as much as strength. Tipo 1, Tipo 2 and whole wheat flours keep more of the bran and germ, which gives the starter more to feed on and the loaf more flavor. A common approach is a strong refined flour for structure with 20–40% Tipo 1, Tipo 2 or whole wheat for taste.

To keep the starter itself healthy, see our Starter feeding page: refined flours work best for regular feedings.

Common questions

Which flour is best for sourdough bread?

A strong flour with some whole grain. Tipo 1 and Tipo 2 give flavor and active fermentation, while a strong refined flour keeps the crumb open. Mariani Zeta and Petra 5078 are two popular choices.

Should I feed my starter with the same flour I bake with?

Not necessarily. Many bakers feed with a refined, strong flour for a stable starter and bake with a more rustic blend. See the Starter feeding page.

How strong should sourdough flour be?

For long or cold fermentation, W 300–360 is a good range. For a shorter, same-day sourdough, a Medium to Strong flour is enough.
