Skip the wait and start baking with confidence. Our mature sourdough starter is grown to full strength before being gently freeze-dried to lock in its activity, flavor, and wild yeast biodiversity. Once you rehydrate it at home, it quickly springs back to life—ready to give your bread a beautiful rise, rich aroma, and authentic sourdough character.
Unlike fresh starters, freeze-drying ensures long shelf life and easy storage without sacrificing the integrity of the culture. That means you can keep it on hand, travel with it, or gift it, all while knowing it will revive into a vigorous, reliable starter when you’re ready to bake.
Perfect for both beginners who want a forgiving starter and experienced bakers who demand consistency, this is sourdough made simple—without compromising on tradition.
At Rustic Roots, we do one thing and one thing only. By limiting what we do, our focus stays on what we do best, sourdough starter!
Ingredients: Organic Non GMO Flour, Mineralized Water.
We use a 170+ year old starter for a tried and true, consistent starter. Most customers say they can begin to activate their starter on a Friday and it’s ready to use Monday afternoon!
San Francisco-style sourdough is known for its crisp, chewy crust and tangy, complex flavor. This signature taste comes from the unique wild yeast and bacteria in the region, particularly Lactobacillus sanfranciscensis, which thrives in the cool, foggy climate. With a long fermentation process, it develops a deep, slightly sour flavor and a soft, airy crumb, making it a beloved classic among bread enthusiasts.
