Spelt sourdough — a 40% spelt blend with open crumb

A 40% spelt sourdough at 78% hydration. Nutty, tender, faster fermenting than wheat, and an excellent introduction to ancient grains.

Spelt is the gateway ancient grain. It looks like wheat, tastes deeper, and ferments faster — which is the most important thing to remember when you bake with it. Cut your timeline by about 20% and the dough rewards you with a tender, slightly sweet crumb.

Why this works

Spelt has weaker gluten than modern wheat. Long bulk fermentations overproof spelt dough, leading to slack, blowout-prone loaves. Shorter fermentation + 78% hydration produces a tender open crumb without losing structure.

Directions

Common questions

Watch the dough, not the timer
Every spelt batch ferments slightly differently. Trust your eyes — surface bubbles and a 50% rise mean it is time to shape.

Baker notes

  • Whole spelt is darker; sifted spelt is lighter and more bread-flour-like. Whole gives more flavor.
  • If you sense the dough overproofing during shape, refrigerate immediately.
  • Spelt sourdough toasts beautifully — try it with butter and honey.

FAQ

Can I go 100% spelt?

Yes — drop hydration to 72%, increase starter to 25%, and cut bulk to 3 hours. Expect a tighter crumb.

Where to go next

Spelt is the loaf for the household member who normally avoids whole grain. The nuttiness wins them over.
