San Francisco Style Sourdough Starter

Best Customer Service Ever!

I’ve used my own home-cultured sourdough for years, but missed good old-fashioned San Francisco Sourdough. The first SF Sourdough I purchased never really took hold. After consulting with Cultures For Health, they sent me a replacement which is coming along nicely. I’m so impressed with their customer service and can’t wait to bake my first loaf with this new San Francisco Sourdough starter!
