The Secret to Choosing the Best Types of Flour for Sourdough

A lively starter, a patient rise, and a crackling crust all begin with one humble ingredient: flour. Understanding the different types of flour for sourdough helps you shape everything from the strength of your dough to the flavor and texture of the finished loaf. At Butte Creek Mill, we believe real ingredients and time-honored milling make every slice more meaningful.

Why Does Flour Make Such a Difference?

Think of gluten as the tiny construction crew inside your dough. When flour and water meet, gluten-building proteins form a stretchy network that holds the gases produced during fermentation. Strong wheat flour generally builds a loftier loaf, while whole-grain and rye flours bring minerals, natural microorganisms, deeper flavor, and distinctive texture to the party.

In our experience, the best flour is not always a single flour. Blending lets you give your dough dependable structure while adding the wholesome character of stone-ground grains. Water absorption varies, too, so our team recommends holding back a little water and adding it gradually until the dough feels supple rather than soupy.

Which Butte Creek Mill Flours Should You Try?

Mill Stone Blend Flour: A Ready-Made Sourdough Partner

Our Mill Stone Blend Flour was made with sourdough in mind. We finely sift stone-ground hard white and hard red wheat flours, then complete the blend with 10% stone-ground rye. The wheat provides structure, while rye contributes flavor and fermentation-friendly whole-grain goodness. It is a welcoming place to begin when you want balanced results without creating your own blend.

Stone Ground Artisan Bread Flour: Hearty and Full-Flavored

For a more rustic loaf, choose our Stone Ground Artisan Bread Flour. Its blend of 80% stone-ground hard red wheat and 20% dark rye retains more bran and germ, creating a rich, nutty flavor and dense, satisfying crumb. Try it when your dream loaf is bold, wholesome, and ready for a generous swipe of butter.

Stone Ground Rye Flour: A Flavorful Boost

Stone Ground Rye Flour can bring earthy flavor, a darker color, and extra character to wheat-based dough. Rye has less gluten-forming ability than wheat, so we recommend beginning with a modest portion in your loaf rather than swapping it one-for-one. It is also a popular flour for feeding starters because whole-grain rye provides abundant food for fermentation.

How Can You Start a Gluten-Free Sourdough Tradition?

Bakers avoiding wheat can still enjoy the tangy flavor and satisfying ritual of homemade sourdough. The Gluten-Free Sourdough Starter Culture available from our online store is cultivated with organic, non-GMO brown rice flour and then freeze-dried to preserve its fermentation power.

Simply activate the culture with flour and water to create a living starter you can maintain with regular feedings. Once it becomes lively and dependable, use it to make sourdough bread, pizza crust, pancakes, and other wholesome favorites. In our experience, caring for a starter soon becomes a comforting kitchen rhythm—and every bubbly rise feels like a little bit of magic.

How Should You Store a Fresh Sourdough Loaf?

Once your loaf has cooled completely, proper storage helps protect the reward for all that mixing, folding, and waiting. Our Reusable Beeswax Bread Bags create a breathable barrier that helps maintain moisture and airflow. That balance keeps bread fresher while helping preserve the crust better than an airtight plastic bag.

Each set includes two extra-large 13-by-17-inch bags made with GOTS-certified organic cotton and a natural beeswax blend. They can be used on the counter, in the refrigerator, or in the freezer, and their reusable, compostable design reduces single-use plastic waste. A sturdy buckle doubles as a convenient handle—simple, useful, and made for everyday bread traditions.
