I feel a special bond with this starter as it’s the first one I transformed into a low carb heirloom. During the mid-1800s (1875) San Francisco Gold Rush, miners carried sourdough starters to bake bread in the rugged frontier. The region’s unique climate gave rise to Lactobacillus sanfranciscensis, which contributed to the distinct tang of San Francisco sourdough. Miners even slept with their starters to keep them alive through freezing nights, earning the nickname “sourdoughs.” Some strains trace back over 150 + years. Inspired by this history, I experimented with several San Francisco starter derivatives to create the perfect base for Sinless Sourdough. After testing multiple strains, I found one that traveled from San Francisco to Toronto—an incredibly robust culture ideal for low carb baking. With its highly active lactobacilli and yeast, it ferments exceptionally well in a low carb environment. Sinless Sourdough Low Carb 150-Year-Old San Francisco DSS is a fermentation powerhouse that thrives with the right care.

This 150-year-old San Francisco Gold Rush strain is a true gem, offering a robust and lively starter that brings plenty of character to your kitchen. With a vibrant, active culture and a delightful fresh tanginess that greets you right from the nose, it’s perfect for those who crave that classic, irresistible sourdough flavor. Expect consistently wonderful results, whether you’re baking bread or other delicious treats.
