Freeze Dried San Francisco Sourdough Starter Culture (5g)

Bring the heart of San Fran into your home and replicate the city’s famous sourdough loaf with our Freeze-Dried San Francisco Sourdough Starter. So, what makes this sourdough so special?

Our San Francisco sourdough starters come from the Fishermans Wharf area, allowing you to keep the authenticity of the original bread. Containing a specific mixture of a unique local strain of bacteria called L. sanfranciscensis.

Our freeze dried sourdough starters offer the same quality of sourdough as our fresh starters with the added bonus of a greater shelf life. Each freeze-dried sourdough starter ships with a 5 year best before date.

Local bakers, including Boudin founded in 1849, swore that no one could reproduce it outside a 50-mile radius of the city – thus adding to its allure. The San Francisco foggy climate cultivated this specific type of yeast, which scientists have now identified in a number of places around the world. However the strain of bacteria is still named after San Francisco, where it was first discovered.

Very Strong, extremely active and always fresh. It is over 150 years old!

A mature, well aged sourdough starter has a much stronger and distinctive sourdough flavour than one recently started from scratch. We have worked hard to obtain the very best sourdough from across the world and we feed our sourdough starter cultures three times a day before freeze drying ensuring that what you purchase from us is a very active, starter culture.

For home use you should keep it in the fridge and feed it only once a week. It is remarkably resilient and will live forever if taken care of properly.
