Heirloom Sourdough Starter Culture — San Francisco, Whole Wheat or Gluten-Free

An heirloom sourdough starter culture in three characters: tangy San Francisco, hearty whole wheat, or a gluten-free culture for households that need one. Heirloom means it keeps going — one packet, fed properly, is every loaf you'll bake from here on.

• Choose San Francisco, Whole Wheat or Gluten-Free
• Heirloom culture — maintained indefinitely rather than used up
• Forgiving enough for a first-time baker
• Instructions included in the packet

Sourdough is the easiest of the home cultures to keep alive, which is why it's where most people start. Miss a feeding and it sulks; it rarely dies.
