Our Specialty Cultures

Every culture we craft is designed to help you achieve that unmistakable crunch and airy interior.

Pure, unpredictable, and incredibly delicious wild cultures.

Everything you need to transition from novice to pro baker.

Infused cultures that bring complex aromas to your loaf.

It started in a flour-dusted kitchen with a single jar of wild starter. We wanted to share the magic of slow fermentation with everyone.

To empower home bakers with the highest quality, most reliable specialty yeast cultures in the world.

A world where every household can enjoy the smell of fresh, artisanal bread made from scratch.

Purity of ingredients, respect for tradition, and a deep love for the science of baking.
