The Puratos Sourdough Library
From Wikipedia, the free encyclopedia
The Sourdough Library was founded in October 2013 in Saint-Vith, Belgium,[1] and is the only facility in the world dedicated to housing sourdough cultures.[2] The library is housed at the Puratos Center for Bread Flavour,[3] with a mission to conserve and promote sourdoughs from around the world, to conduct research, and to ensure the survival of the various strains for future use.[4] It currently has over 900 strains of wild yeast and lactic acid bacteria recorded.[5] Every new sample that arrives at the library is checked and analyzed in the laboratory, run by Professor Marco Gobbetti.[6] The library is a not-for profit initiative from Puratos and as of 2016 has 87 sourdoughs, including 12 from the United States.[7]
