Pairs well with
San Francisco Sourdough
San Francisco Sourdough is famous around the world and it was originally created by accident. French bakers in San Francisco were perplexed as to why the bread that they were making was going sour in San Francisco, turns out its they had struck gold as everyone loved the way the bread tasted.
This starter is available as a live fresh starter and also dehydrated. if you are buying this as a gift or you are unlikely to get started within 2 weeks of the culture arriving please choose the dehydrated culture.

San Francisco sourdough contains a specific strain of bacteria- L. sanfranciscensis which is responsible for its unique sour flavour and taste. San Francisco is widely regarded as the mecca of sour-style bread and in the 1980s the San Francisco artisan bread movement reinvigorated our bread-making image with an emphasis on great technique.
Our heirloom Culture Originates from San Francisco, the flavour is unique distinctive and amazing. A firm favourite for its ease of use, versatility and flavour.
