The Global Sourdough Project:

Publication Figures

We weren’t able to include all of the information we wanted in our published images. Perhaps the most important piece of information we had to leave out: references to individual sourdough sample numbers. We want to make sure that those of you who sent us a sample of your starter have can compare you sample to other samples we received. To understand how your starters microbiome is reflected in our broader findings we have created a set of figures that match the figures in the publication, but that include sample ID numbers whenever possible.
