The Sourdough Library

Nothing demonstrates our commitment to bread making more than the Puratos Sourdough Library. Set within the Center for Bread Flavor, the Sourdough Library aims to safeguard sourdough biodiversity and preserve the sourdough heritage and baking knowledge, and is the first of its kind in the world.

The idea is simple but important. If a baker wants to safely store a sample of sourdough, they can bring it to the library where we will analyze the contents and identify its precise composition and ingredients. Safe in the library, the sample can then be kept alive and maintained for years to come.

We are pleased to say that the library is now home to a unique collection of sourdoughs from bakers across the globe and has contributed to the identification of more than 700 types of yeast and more than 1,500 varieties of lactic acid bacteria.
