9 Best Whole Wheat Flour for Sourdough Bread (November 2026)
The best whole wheat flour for sourdough bread include the Palouse Brand Certified Glyphosate Residue Free Bread for traceable whole-grain baking, the Sunrise Flour Mill Heritage Organic Whole Wheat for fine heritage wheat flour, and the Eurasian Legacy Imported Lab-Tested Glyphosate-Free Wheat Flour for high-protein sourdough.
On this page (5 sections)
The best whole wheat flour for sourdough bread is Palouse Brand Certified Glyphosate Residue Free Bread Flour for most home bakers. It combines whole wheat flour, a 10–12% protein range, a mild flavor and a resealable 3 lb bag.
Choose Sunrise Flour Mill Heritage Organic Whole Wheat if you want a 5 lb heritage flour with an ultra-fine grind. Choose Eurasian Legacy if the stated 12–13% protein range is your main priority.
Whole wheat flour adds the bran and germ along with the endosperm, so it brings more wheat flavor and a denser feel than white bread flour. It can also absorb water differently, which is why your dough may need adjustments from one brand or wheat variety to another.
If you want to compare flour types before choosing a bag, our guide to bread flour explains how protein and flour strength affect dough. You can also read what sourdough bread is made of for the role of flour, water, salt and starter.

The best whole wheat flour for sourdough bread by baking goal
Palouse Brand is the strongest all-around pick, while Sunrise and Eurasian Legacy suit different priorities. The right flour depends on whether you care most about whole-grain traceability, a fine heritage grind, protein or package size.
Our score weighs specs, features and buyer feedback against what you're shopping for. We compared the stated wheat types, flour labels, protein ranges, package sizes, certifications and intended bread uses.
Palouse Brand Certified Glyphosate Residue Free Bread: Best for traceable whole-grain baking
- 3 lb resealable bag
- Whole wheat unbleached flour
- Certified glyphosate residue free
- 10–12% protein
A strong all-around choice for sourdough bakers who want whole-grain flour, a mild flavor and farm traceability. The 3 lb resealable bag suits regular home baking without taking over the pantry.
Pros
- Whole wheat flour
- Resealable bag
- USA grown and field traced
Cons
- Lower stated protein than some bread-focused options
- Whole-grain flour may need more liquid
Palouse Brand is the best starting point for a baker who wants a clearly identified whole wheat flour for sourdough. The 3 lb bag is large enough for regular loaves but smaller than the bulk packs in this group.
Its stated protein range is 10–12%, with strong gluten listed for one use description and weaker gluten listed for another. That means it can work well in a sourdough blend, but your dough may need more care than a high-protein bread flour.
The flour is unbleached and milled from whole wheat berries. Palouse Brand also describes the wheat as grown on its Washington family farm, triple cleaned and field traced.
A resealable bag helps limit pantry mess after you measure flour. Since whole wheat flour retains natural oils, move it to an airtight container if you plan to store it for a longer period.
Choose Palouse Brand when you want a mild whole-grain profile, a 3 lb size and farm traceability. It is also a natural choice for bakers who want flour for artisan bread and sourdough rather than only cakes or pastries.
Sunrise Flour Mill Heritage Organic Whole Wheat: Best for fine heritage wheat flour
- 5 lb bag
- USDA Organic whole wheat flour
- Milled from red hard wheat
- Ultra-fine grind
This 5 lb organic heritage flour is aimed at bakers who want a fine grind and a rich, nutty wheat flavor. Its single-pass milling approach is useful when you want whole wheat bran integrated into a smoother dough.
Pros
- 5 lb package
- Organic
- Ultra-fine grind
Cons
- Protein percentage is not stated
- Heritage wheat may behave differently from modern wheat
Sunrise Flour Mill Heritage Organic Whole Wheat is best for bakers who want a 5 lb organic heritage flour with a fine texture. It is milled from red hard wheat and uses a single-pass milling approach.
The ultra-fine grind may make bran integration easier than a visibly coarse whole wheat flour. That can be useful when you want whole-grain flavor while working toward a smoother dough.
Sunrise describes this flour as rich and nutty, with nutrients and micronutrients retained as a whole-grain flour. The 5 lb bag suits weekly sourdough baking better than the smaller packages here.
The stated product information does not give a protein percentage, so you cannot compare its gluten potential directly with Eurasian Legacy or King Arthur. Watch the dough during mixing and folding instead of relying on the package size or heritage label.
Pick it for an organic, fine-ground whole wheat flour with a heritage wheat profile. For starter feeding, compare it with our guide to the best whole wheat flour for sourdough starter.
Eurasian Legacy Imported Lab-Tested Glyphosate-Free Wheat Flour: Best for high-protein sourdough
- 12–13% protein
- 3 lb resealable stand-up pouch
- Unbleached and non-GMO
- Lab-tested glyphosate and pesticide free
The highest stated protein range in this group makes it a strong candidate for dough that needs more gluten structure. It is not USDA certified organic, but it is unbleached, non-GMO and sold in a resealable pouch.
Pros
- Highest stated protein range
- Resealable pouch
- Unbleached and non-GMO
Cons
- Not USDA certified organic
- Not identified as whole wheat in the title
Eurasian Legacy is the best choice when protein is the clearest buying priority. Its stated 12–13% protein range supports dough that needs more gluten structure for sourdough, pizza and artisan bread.
For that use, compare whole wheat flour for pizza.
The flour is unbleached, non-GMO and sold in a resealable 3 lb stand-up pouch. That package size gives occasional bakers a practical amount without committing to a 10 lb or 12-pack supply.
Eurasian Legacy describes the wheat as imported from Kazakhstan and independently lab-tested for glyphosate and AMPA below the stated detection threshold. It is not USDA certified organic, so shoppers who need organic certification should choose another product here.
The title identifies it as wheat flour for bread, sourdough and all-purpose baking, but it does not identify it as whole wheat flour. Treat that distinction seriously if you want all the bran and germ in your loaf.
Choose it for high-protein sourdough structure and a resealable pouch. Choose Sunrise, Fairhaven Mill or Palouse Brand when a clearly labeled whole wheat flour is more important.
Jovial Organic Einkorn Whole Wheat Flour: Best for einkorn sourdough flavor
- 32 oz, 3-pack
- USDA Organic
- Non-GMO Project Verified
- Whole wheat einkorn
Jovial brings einkorn's nutty flavor and weak gluten to sourdough baking. It suits bakers who want an ancient wheat with a distinctive taste, but einkorn dough needs different handling from modern wheat dough.
Pros
- Three 32 oz packages
- Organic einkorn
- Nutty flavor
Cons
- Weaker gluten
- Not safe for people with celiac disease
Jovial Organic Einkorn Whole Wheat Flour suits bakers who want einkorn's nutty flavor and weaker gluten. The 3-pack contains three 32 oz packages, for 96 oz total.
Einkorn is an ancient wheat with gluten, so it is not safe for people with celiac disease. Jovial describes its gluten as weaker and says the flour is often tolerated by people sensitive to modern wheat, but individual tolerance varies.
The flour is USDA certified organic, Non-GMO Project Verified, unbleached, unbromated and unenriched. It is made in Italy and has a silky texture with a buttery yellow color.
Einkorn does not behave exactly like modern hard wheat. Expect to adjust your mixing, hydration and fermentation approach rather than substituting it blindly in a familiar sourdough formula.
Pick Jovial when flavor, organic einkorn and a multipack matter more than maximum gluten strength. If you want a different grain for sourdough, see our comparison of the best rye flour for sourdough bread.
Sunrise Flour Mill Heritage Whole Wheat Bread: Best for heritage bread blends
- 5 lb bag
- Organic heritage hard red and soft white wheat blend
- Unbleached
- Non-GMO
This blend combines organic heritage hard red wheat with soft white wheat for a wheaty flavor and tender crumb. It is a useful middle ground when you want whole-grain character without choosing a single wheat variety.
Pros
- 5 lb package
- Hard and soft wheat blend
- Organic and unbleached
Cons
- Blend proportions are not stated
- Protein percentage is not stated
Sunrise Flour Mill Heritage Whole Wheat Bread Blend is a good fit for bakers who want a blend of hard red and soft white heritage wheat. The 5 lb bag gives you enough flour for repeated sourdough and sandwich loaves.
The hard red wheat contributes a wheaty flavor, while soft white wheat can make the blend feel less one-dimensional than a single hard-wheat flour. Sunrise describes the result as suitable for rustic sourdoughs and sandwich bread.
It is organic, unbleached, non-GMO and grown without glyphosate according to the product title and features. The blend is also described as naturally high in fiber and intended to produce a tender crumb.
No protein percentage is stated, so use the dough's strength and rise as your guide. If your loaf feels heavy, blend this flour with a stronger white bread flour or increase fermentation time carefully.
Choose this blend when you want one 5 lb bag that bridges rustic sourdough and softer sandwich bread. It is less suited to shoppers who want a single wheat variety or a confirmed protein number.
365 by Whole Foods Market: Best for bulk organic baking
- 80 oz per pack, 2-pack
- 100% organic whole wheat flour
- Dark northern spring wheat
- Grown on USA family farms
The 2-pack provides 10 lb total for bakers who use whole wheat flour often. Dark northern spring wheat gives the flour a distinctive nutty flavor, making it practical for sourdough, pizza dough and rolls.
Pros
- 10 lb total
- Organic whole wheat
- Dark northern spring wheat
Cons
- Large quantity needs good storage
- Protein percentage is not stated
365 by Whole Foods Market is the best option for bulk organic whole wheat baking. The 2-pack contains 80 oz per pack, for 160 oz or 10 lb total.
The flour is made from dark northern spring wheat grown on USA family farms. That wheat gives the flour a distinctive nutty flavor and suits breads, pizza dough, dinner rolls, muffins and pancakes.
A 10 lb supply works well if whole wheat sourdough is part of your weekly routine. It needs more storage planning than a 2 lb or 3 lb bag, especially because whole-grain flour retains natural oils.
Use an airtight container that is large enough for the full amount, or divide the flour into smaller containers. Freezing is another option when you expect the flour to sit for an extended period.
Choose 365 when the best value for your routine is a large organic supply from a familiar whole wheat variety. Skip it if you bake sourdough only occasionally and do not have cool, dry storage.
Fairhaven Mill 100% Organic Whole Wheat Bread: Best for fine-ground sourdough
- 5 lb bag
- Fine ground
- Washington-grown Buck Pronto hard-red wheat
- Organic and non-GMO
Fairhaven Mill uses fine-ground organic whole wheat flour for smoother dough handling and absorption. It fits sourdough bakers who want a clear hard-red wheat flavor and a flour that also works for rolls, pizza crusts and flatbreads.
Pros
- Fine-ground texture
- Organic and non-GMO
- 5 lb package
Cons
- Protein percentage is not stated
- Whole-grain flour is more perishable than refined flour
Fairhaven Mill is the best pick for fine-ground organic whole wheat sourdough. Its 5 lb bag is made from Washington-grown Buck Pronto hard-red wheat and is milled to a fine texture.
Fine grinding can help the flour absorb water smoothly and make dough easier to handle. Fairhaven Mill positions it for sourdough, artisan bread, sandwich bread, rolls, pizza crusts and flatbreads.
The flour is certified organic and non-GMO. Its whole-grain profile also contributes natural fiber, protein and minerals, while the hard-red wheat brings a clear wheat flavor.
The product information does not state a protein percentage, so you cannot use a number to predict dough strength. Start with the hydration in your recipe, then add water gradually if the flour remains dry after mixing.
Pick Fairhaven Mill when grind and organic certification matter most. Store it in an airtight container because whole-grain flour is more perishable than refined flour.
Great River Milling Organic Whole Wheat Flour: Best for small-batch baking
- 2 lb package
- High-protein whole wheat flour
- USDA Organic
- Unbleached and unbromated
The compact 2 lb package works well for first-time buyers and bakers who use whole wheat as part of a blend. Great River Milling positions it for sourdough, sandwich loaves, rolls, pizza dough and rustic baking.
Pros
- Small pantry size
- Organic
- Works for several bread styles
Cons
- Least flour in the group
- Exact protein percentage is not stated
Great River Milling is best for small-batch sourdough baking. The 2 lb package makes it a practical choice for first-time buyers, smaller households and bakers who use whole wheat as part of a blend.
It is USDA organic, non-GMO, kosher, unbleached and unbromated. Great River Milling describes it as high protein and suitable for sourdough, sandwich loaves, rolls, pizza dough, muffins and rustic baking.
The compact package reduces the risk of keeping more flour than you can use while it is fresh. It also lets you test how a particular whole wheat flour behaves before buying a larger supply.
The exact protein percentage is not stated, so compare the dough rather than assuming it will act like a strong white bread flour. Whole wheat particles can still make dough feel heavier even when the flour is described as high protein.
Choose it when you want a certified organic flour in a manageable amount. It also makes sense for recipes that use whole wheat alongside another bread flour.
King Arthur: Best for sturdy whole-wheat flavor
- 2 lb packages, 12-pack
- 100% organic hard red wheat
- 14% protein
- Non-GMO Project Verified
King Arthur offers the highest stated protein percentage here in individually sized 2 lb packages. The 12-pack suits bakers who want to keep a large supply of organic whole wheat flour while using smaller portions at a time.
Pros
- 14% protein
- Organic hard red wheat
- Twelve 2 lb packages
Cons
- Large total quantity
- Strong whole-wheat flavor may not suit mild loaves
King Arthur is best for bakers who want a stated 14% protein level and a large organic supply. The product comes as twelve 2 lb packages, giving you 24 lb total.
The flour is milled from 100% organic hard red wheat and has a classic sturdy whole-wheat flavor. Its high stated protein can help support dough structure, while the hard red wheat keeps the loaf's flavor distinctly wheaty.
The individual 2 lb packages make the large quantity easier to portion than one oversized bag. They also give you a simple way to keep unopened flour separate from the package currently in use.
King Arthur is USDA approved organic, QAI certified organic, Non-GMO Project Verified and certified kosher. The company recommends freezer storage for the freshest taste, with a cool, dry place as another option.
Choose it for frequent baking, strong whole-wheat flavor and a clear protein number. Skip the 12-pack if you bake only a few loaves a year or lack room for bulk storage.
How much whole wheat flour should you use in sourdough?
Start with 20% to 50% whole wheat flour in a familiar sourdough recipe, then adjust hydration and fermentation based on the dough. A smaller percentage gives you whole-grain flavor while keeping more of the handling behavior of white bread flour.
A 100% whole wheat loaf can work, but it usually needs more attention. Bran can interrupt gluten development, and whole wheat flour often absorbs water slowly as the dough rests.
Autolyse or rest the mixed flour and water before adding the starter and salt if your recipe allows it. This gives the flour time to hydrate and can make the dough easier to stretch.
Do not judge readiness only by the clock. Look for a dough that has gained volume, feels aerated and holds its shape according to the fermentation method you use.
Which flour features matter most for sourdough?
Protein, wheat variety, grind and package size matter most when you choose whole wheat flour for sourdough. Certifications and storage features matter too, but they do not replace observing how the dough behaves.
Protein and gluten strength
A higher stated protein percentage may help dough hold structure, but it is not the only factor. King Arthur states 14% protein, while Eurasian Legacy states 12–13%.
Palouse Brand gives a 10–12% range.
Those numbers are not a complete performance guarantee. Whole-grain particles, fermentation time and hydration all affect the final loaf.
Wheat variety and flavor
Hard red wheat usually gives a stronger wheat taste than a mild white-wheat blend. Einkorn has a distinctive nutty flavor and weaker gluten, while Sunrise's heritage blend combines hard red and soft white wheat.
Choose the wheat variety based on the loaf you want to eat. A strong flavor may suit rustic bread, but a milder flour may work better for sandwiches.
Grind and bran texture
Fine-ground flour can absorb water more evenly and may feel smoother during mixing. Fairhaven Mill and Sunrise Flour Mill are the clearest fine-grind choices in this group.
A coarser flour is not automatically poor for sourdough. It simply may need more rest, hydration adjustment or a blend with another flour.
Package size and storage
Buy 2 lb or 3 lb if you are testing a flour or bake only occasionally. Choose 5 lb for regular weekly baking, and choose the 10 lb or 12-pack options only if you have a storage plan.
Keep flour away from heat, moisture and strong odors. Airtight storage helps preserve quality, while freezing can extend freshness when you will not use the flour quickly.
Can whole wheat sourdough flour go in a bread maker?
Yes, whole wheat flour can work in a bread maker, but the machine's program and liquid ratio still matter. Our guide explains whether you can use whole wheat flour in a bread maker and what to watch during mixing and rising.
Bread makers can be less forgiving when a whole wheat dough needs extra hydration or a longer rest. Measure consistently, use the machine's whole-wheat or custom cycle when available, and check the dough early in the mixing stage.
For machine-specific flour choices, see the best whole wheat flour for bread machines. A flour that makes a tall free-form boule may still need a different water level in a bread-machine pan.
Best whole wheat flour for sourdough bread: final verdict
Palouse Brand is the best overall match for whole wheat sourdough when you want a 3 lb resealable bag, mild whole-grain flavor and traceable USA-grown wheat. Sunrise is the better fit for a fine heritage flour in a 5 lb bag.
Pick Eurasian Legacy for its stated 12–13% protein and strong dough structure, but remember it is not USDA certified organic and is not identified as whole wheat in the title. Pick Jovial for einkorn flavor and weaker gluten, or King Arthur for 14% protein and bulk storage.
If you need a flour for a special dietary approach, compare the best gluten free flour for sourdough bread separately. Gluten-free dough follows different rules and should not be treated as a direct substitute for wheat flour.

Frequently asked questions
What is the best whole wheat flour for sourdough bread?
Palouse Brand is the best overall choice here because it combines whole wheat flour, a 10–12% protein range, a mild whole-grain flavor and a resealable 3 lb bag. Choose a higher-protein option if you want more gluten strength, or an einkorn flour for a distinct ancient-wheat flavor.
Can you use 100% whole wheat flour in sourdough bread?
Yes, but 100% whole wheat sourdough usually needs careful hydration and fermentation control. Bran and germ make the flour denser and can affect gluten development.
Start with a manageable hydration, rest the dough, and adjust water as the flour absorbs it.
Is high-protein flour better for whole wheat sourdough?
High-protein flour can help provide stronger gluten structure, especially when whole-grain particles make dough feel heavier. Eurasian Legacy states 12–13% protein and King Arthur states 14%, but protein alone does not determine the final loaf.
Grind, wheat variety and hydration also matter.
Should whole wheat flour for sourdough be organic?
Organic flour is a preference, not a requirement for sourdough fermentation. Several picks here are organic, including Sunrise, Jovial, Fairhaven Mill, Great River Milling, 365 by Whole Foods Market and King Arthur.
Check the package certification that matters to you before buying.
How should you store whole wheat flour?
Store whole wheat flour in an airtight container in a cool, dry place, and consider freezing it for longer storage. Whole-grain flour retains natural oils, so it can become stale faster than refined flour.
Keep the container dry and label it with the opening date.
