The Best Gluten-Free Sourdough Bread in 2026: 6 Brands Compared (Honestly)

If you've searched "best gluten-free sourdough bread," you already know the problem. Half the loaves labeled "sourdough" are ordinary gluten-free sandwich bread with a little cultured flour for flavor. The rest are hard to find, cost a fortune to ship, or fall apart the moment they meet a toaster.

We're a dedicated gluten-free vegan sourdough bakery in Chaska, Minnesota, so yes, we have a horse in this race. That's why we kept this comparison factual. Every competitor's ingredient list below comes straight from the brand's own website or a major retailer listing (checked September 2026), with links so you can verify it yourself.

We compared the gluten-free sourdough brands people search for and recommend most: Schär, Canyon Bakehouse, Bread SRSLY, Franz, and Young Kobras. Then we compared our own bread against them.

What makes gluten-free bread real sourdough?

Before the brands, a quick definition. Real sourdough is leavened by a wild fermented starter, a living culture of wild yeast and lactic acid bacteria. Given time, that fermentation creates the tang, the chewy crumb, and the crackly crust people miss.

Many gluten-free "sourdough-style" breads take a shortcut. They rise with commercial yeast and add a small amount of cultured rice flour or acids for a sour note. Most also rely on gums or cellulose binders (xanthan gum, guar gum, modified cellulose, HPMC) to imitate gluten's stretch. None of this is unsafe, but it's a different product. Many people also find that gums leave bread gummy, or that they don't agree with their stomach.

(We go deeper in Commercial Yeast vs. Wild-Fermented Starter: What's Actually Different?.)

So we compared every loaf on five things:

1. Is it leavened by a wild starter, or by commercial yeast?
2. Does it contain gums or cellulose binders?
3. Does it contain eggs or soy (important if you're vegan or have multiple allergies)?
4. How is it sold: a grocery shelf, the freezer aisle, or baked to order?
5. What does it cost?

Prices and formulas change, so check each brand's current listing before you buy.

1. Schär Deli Style Sourdough

Schär is the most widely available gluten-free bread brand in the U.S. Registered dietitians frequently recommend it: Women's Health cites its chewy texture, fiber, and value. BakingSubs calls Schär Deli Style "the only gluten-free sourdough with real tang" among grocery loaves (BakingSubs).

What's in it: Corn starch, water, sourdough (rice flour, water), buckwheat flour, rice flour, rice syrup, psyllium seed husk, rice starch, sunflower oil, soy protein, sorghum flour, modified cellulose, yeast, salt, sugar (Schär).

Best for: An affordable, easy-to-find loaf for sandwiches.

Keep in mind: The first ingredient is corn starch. It contains soy and uses yeast and modified cellulose alongside its sourdough culture. At 240 g, the package is small.

How Heaven compares: Our loaves start with organic buckwheat and a wild fermented starter. They contain no corn, soy, yeast, or cellulose, and they're baked to order rather than shelf-stable.

2. Canyon Bakehouse Sourdough-Style

Canyon Bakehouse is a freezer-aisle staple, and many gluten-free shoppers consider it the gold standard for sandwich bread. Its Sourdough-Style loaf is newer and is labeled "sourdough-style" rather than sourdough.

What's in it: Water, brown rice flour, tapioca flour, yeast, whole grain sorghum flour, potato starch, cultured brown rice flour, canola oil, tapioca starch, eggs, cane sugar, and 2% or less of xanthan gum, egg whites, sea salt, lactic acid, acetic acid, fumaric acid, and enzymes (Canyon Bakehouse).

Best for: A soft, familiar sandwich loaf you can grab at the grocery store. It keeps 7–10 days out of the bag or up to 3 months frozen.

Keep in mind: It rises with yeast, gets its sour note from cultured flour and added acids, and contains eggs and xanthan gum, so it isn't vegan.

How Heaven compares: Our bread is fully vegan (no eggs, no dairy) and leavened only by wild fermentation. It has no added acids, gums, or cane sugar.

3. Bread SRSLY Classic Sourdough

Bread SRSLY, a San Francisco bakery, is one of the most-recommended gluten-free sourdough brands online. Goodnature named it its top gluten-free bread brand, and gluten-free Reddit threads mention it constantly.

What's in it (Classic): Wild fermented sourdough (water, organic white rice flour, organic millet flour, organic sorghum flour, arrowroot, xanthan gum, salt) (Bread SRSLY). The company also sells a separate gum-free, rice-free line.

Best for: People who want a genuinely fermented loaf made in a top-9-allergen-free facility.

Keep in mind: The classic loaf uses xanthan gum. Shipping from the West Coast adds up; one Reddit user balked at "$63 for just TWO loaves of bread… before shipping costs" (r/glutenfree).

How Heaven compares: Every Heaven sourdough is gum-free, not just a specialty line. We bake in the Midwest, so central and eastern U.S. customers get bread that has spent less time in transit.

4. Franz Gluten-Free Deli-Style Sourdough

Franz, a Pacific Northwest bakery, sells its gluten-free sourdough at major grocers. Reddit users often call it one of the better store-bought sandwich breads (r/glutenfree).

What's in it: Water, brown rice flour, tapioca starch, tapioca syrup, cultured rice flour, high oleic safflower oil, potato starch, corn starch, xanthan gum, and 2% or less of sunflower lecithin, salt, yeast, and enzymes (Target).

Best for: A vegan, budget-friendly sandwich loaf from a dedicated gluten-free bakery.

Keep in mind: Like most grocery "sourdough," it uses yeast and cultured flour rather than a long wild ferment, and it contains xanthan gum and corn starch.

How Heaven compares: We skip starches as the base, skip gums, and skip yeast. Our bread is built on buckwheat, millet, and a long wild ferment.

5. Young Kobras Original Sourdough

Young Kobras is a Bay Area bakery that Well+Good ranked among its best gluten-free sourdough breads, praising its 12-hour fermentation and organic ingredients.

What's in it: Sourdough starter (water, organic brown rice flour), organic sorghum flour, organic millet flour, organic tapioca flour, organic psyllium husk, sea salt, organic apple cider vinegar (Young Kobras).

Best for: Shoppers who want a certified organic, gum-free loaf from a dedicated gluten-free and top-14-allergen-free facility.

Keep in mind: It's baked to order and ships once a week from California (Young Kobras).

How Heaven compares: Young Kobras and Heaven share the same philosophy: wild starter, no gums, simple ingredients. The biggest differences are our buckwheat-and-millet base, our wider lineup (Caraway, Dark Flaxseed-Allspice, Multi-Seed, Cranberry & Pecan, plus baguettes and focaccia), and our Midwest location.

6. Heaven Gluten-Free Bakery (us)

Here's what we make, stated as plainly as we described everyone else.

What's in our Original (White) Sourdough: Filtered water, organic buckwheat flour, white rice flour, wild fermented starter (organic buckwheat flour, filtered water), arrowroot flour, organic tapioca flour, millet flour, psyllium husk, organic date syrup, organic tiger nut flour, Himalayan pink salt, extra virgin olive oil.

What we don't use: Xanthan gum, guar gum, commercial yeast, eggs, dairy, soy, corn, refined sugar, or preservatives.

How it's made: Each loaf is naturally fermented for 8+ hours with a starter fed only buckwheat flour and water. We bake to order in our dedicated gluten-free bakery in Chaska, Minnesota.

How it's sold: Online, shipped nationwide by 2-day FedEx (order by Sunday 11 PM; ships Wednesday; arrives Thursday or Friday). We also deliver locally in the Twin Cities. Subscribe and save 10%.

The honest trade-offs: Our bread costs more than grocery loaves because it's small-batch, slow-fermented, and shipped fresh. It isn't shelf-stable. Refrigerate or freeze it when it arrives, and freeze it for up to 45 days. It's also more rustic than squishy sandwich bread: think artisan loaf, not Wonder Bread.

Try it: Start with the Original (White) Sourdough, or the customer favorite Cranberry & Pecan Loaf (contains pecans). To lower your cost per loaf, try a 4-pack or The GF Sourdough Favorites bundle.

If gums bother you, or you want bread that tastes like the sourdough you remember, read the ingredient list first. "Sourdough-style" and "deli-style sourdough" usually mean yeast plus flavor. "Wild fermented starter" with no gums means the real thing. For more on why gums are in gluten-free bread and what replaces them, read Gluten-Free Sourdough Bread Without Gums.

Frequently asked questions

Is gluten-free sourdough actually sourdough?

It can be. True gluten-free sourdough is leavened by a wild starter made from gluten-free flour, with no commercial yeast. Many grocery "sourdough-style" loaves use yeast plus cultured flour or acids for flavor, so check the ingredients.

Which gluten-free sourdough breads have no xanthan gum?

Of the loaves compared here, Heaven Gluten-Free Bakery and Young Kobras list no gums. Bread SRSLY's classic loaf uses xanthan gum, but the brand sells a separate gum-free line. Schär Deli Style uses modified cellulose instead of xanthan gum. Canyon Bakehouse Sourdough-Style and Franz both list xanthan gum.

Is regular sourdough safe for people with celiac disease?

No. Wheat sourdough still contains gluten, even after long fermentation. People with celiac disease should choose sourdough made from gluten-free flours in a dedicated gluten-free facility.

Which gluten-free sourdough is vegan?

Heaven, Schär Deli Style, and Franz are labeled vegan. Canyon Bakehouse Sourdough-Style contains eggs.

How should I store fresh-baked gluten-free sourdough?

Bread baked without preservatives should be refrigerated or frozen soon after arrival. Slice it first, freeze the slices, and toast them straight from frozen. To refresh a whole loaf, thaw it, mist it with water, and bake at 350–400°F for 10–15 minutes.
