San Francisco

The light airy starter the new world created

San Francisco 200

The history of San Francisco sourdough starter is as rich and tangy as the bread it produces. Legend has it that the origins of this iconic starter trace back to the California Gold Rush era in the mid-1800s. During this time, miners and settlers from around the world flocked to San Francisco in search of fortune, bringing with them their own sourdough cultures.

As the story goes, the unique microorganisms present in the San Francisco air and environment combined with the diverse array of sourdough cultures brought by these immigrants gave rise to a distinctively flavorful and robust sourdough starter. This starter, often referred to as “San Francisco sourdough” or simply “San Francisco starter,” became renowned for its tangy taste, chewy texture, and long shelf life.

San Francisco sourdough quickly became a staple of the city’s culinary identity, with bakeries sprouting up across the region to meet the demand for this beloved bread. Its popularity continued to grow throughout the 20th century, solidifying its status as an iconic symbol of San Francisco’s gastronomic culture.

Today, San Francisco sourdough remains a cherished tradition, with bakeries and home bakers alike preserving and perpetuating its legacy. While the exact origins of the San Francisco sourdough starter may be shrouded in myth and legend, its enduring appeal and distinctive flavor continue to captivate bread lovers around the world.
