challenges when reading books about or following recipes on sourdough, there are just so many variables in the equation, and what works for one sourdough doesnâ€™t automatically work the same for another.

Many more have been added since; from around the globe: Italy, Hungary, Greece, USA, China, the Netherlands, and Portugal, to name but a few. They continue to search and add to the collection to keep the library growing so that the true biodiversity can be discovered.
The Puratos Sourdough Philosophy: There are 3 main reasons for the existence of the sourdough library: 1. Preserve the biodiversity of sourdough - All over the world there are plenty of bakers making sourdough. Our aim is to collect and preserve the sourdoughs that are coming MYVTHZWLJPĂ„JYLNPVUTHKLMYVTHZWLJPĂ„JĂ…V\YVYYLJPWLHUKOH]PUNHZWLJPĂ„JZ[VY` etc. The sourdoughs are stored, analysed and documented for the future. 2. Backup - A sourdough is the soul of the bakery. We can always provide a sample back to the donors in case their sourdough will be lost due to a failure in the bakery. 3. Communication - Not only for us, the library is of great value to communicate about. It shows our knowledge on sourdough, V\YWHZZPVUPUIYLHKIHRPUN0[PZ[OLZ`TIVSVMV\YSLHKLYZOPWPUUH[\YHSMLYTLU[H[PVU(JLY[PĂ„JH[LHUKHZ`TIVSPJRL` (to enter the library) is given to the donor in order to communicate towards its customers about the preservation of the ZV\YKV\NON\HYHU[LLPUN[OH[[OLĂ…H]V\Y[OL`SPRLZVT\JO^PSSUL]LYILSVZ[ â€œWe want to understand what makes each one so special, so when they arrive they are analysed in our laboratory to see ^OH[SHJ[PJHJPKIHJ[LYPHHUKUH[\YHS`LHZ[ZTHRL[OLTKPŃœLYLU[;OPZPUMVYTH[PVUPZ[OLUZ[VYLKMVY[OLM\[\YLP[ÂťZWHY[VMV\Y contribution to the worldâ€™s collective knowledge of sourdough breads.â€?
