This recipe combines traditional sourdough techniques with modern shortcuts—like Dutch oven baking—to ensure consistent results even with whole wheat’s challenges.
The key lies in proper hydration adjustments and controlled fermentation, which develop that signature tang and open crumb structure.
Unlike standard recipes, this version balances whole wheat’s density with a foolproof starter process and extended bulk fermentation. You’ll work with a hydration level of 75% (higher than white flour dough) to accommodate whole wheat’s water absorption, while still achieving a light, airy crumb.
The Dutch oven creates steam during baking, mimicking a professional oven’s effect on the crust.
By the final proof, your dough will be jiggly yet resilient, ready for shaping into 50 uniform boules that bake to golden perfection. The result? A loaf with a crisp, caramelized crust and a tender interior infused with whole wheat’s nutty richness.
This method ensures every slice delivers that authentic sourdough experience—even for large-scale baking.
Whether you’re feeding a crowd or stocking a bakery, this recipe delivers restaurant-quality sourdough without the guesswork. The step-by-step approach covers troubleshooting hydration issues, oven spring challenges, and how to adjust proofing times for your climate. Let’s get started on a batch that’ll impress even seasoned bakers.
Ingredients for 50 whole wheat sourdough bread
Fifty servings of restaurant-quality whole wheat sourdough require precise hydration and fermentation control.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Whole Wheat Sourdough Starter 🍞 | 1 ½ cups | 100% hydration, bubbly and active |
| King Arthur Bread Flour (Whole Wheat) 🌾 | 25 lbs | High-protein for structure |
| Unbleached All-Purpose Flour 🌾 | 2 ½ lbs | Balances whole wheat density |
| Distilled Water 💧 | 20 ¼ cups | Room temperature (75°F) |
| Diamond Crystal Kosher Salt 🧂 | 2 ½ tbsp | Fine grain preferred |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For dough handling |
| Honey (for starter feed) 🍯 | ½ cup | Local raw preferred |
| Unbleached White Bread Flour (for starter feed) 🌾 | 2 cups | Boosts starter activity |
| Dutch Oven (or baking stone) 🔥 | 1 whole | 5-7 quart capacity |
| Cornmeal (for dusting) 🌽 | 2 cups | Fine grind preferred |
| Ice Water (for final shape) ❄️ | ½ cup | Chilled to 35°F |
| Baking Parchment Paper 📄 | 1 sheet | For easy transfer |
The King Arthur Bread Flour is non-negotiable here—its high protein content prevents the dense crumb whole wheat typically creates. King Arthur and Bob’s Red Mill are the gold standards for professional bakers, but Whole Foods bulk bins often carry comparable quality at a fraction of the cost. For the starter, maintain a 100% hydration ratio (equal parts flour and water by weight) to develop maximum tang. Feed it nightly with unbleached white flour and honey—the honey’s enzymes accelerate fermentation without overpowering the whole wheat flavor. If your kitchen runs warm, reduce feedings to every 24 hours; cooler climates can stretch to 36 hours.
Short on whole wheat flour? Substitute up to 20% white flour to improve oven spring, but expect less nutty depth. No Dutch oven? A baking stone preheated to 475°F with steam pans works nearly as well. For the hydration adjustment, start with 70% and increase to 75% if the dough feels too stiff—whole wheat absorbs water differently than white flour. The ice water in final shaping isn’t optional; it tightens the gluten structure for those signature open crumb holes. Pre-ferment the dough for 4-6 hours at 75°F—longer fermentation develops more complex flavors but risks overproofing in warm kitchens.
Store finished loaves in paper bags at room temperature for up to 5 days to maintain crispness. For longer storage, freeze fully cooled boules wrapped in parchment and plastic—thaw at room temperature before slicing. The Dutch oven retains heat exceptionally well, so preheat it for 60 minutes before baking. If shaping 50 boules feels overwhelming, divide the dough into 10 batches and bake sequentially. Each loaf will yield 10 slices, perfect for crowd feeding or bakery display. The starter can be revived after 2 weeks in the fridge by feeding it daily for 3-5 days before use.
Why You'll Love This Recipe

- Deep, Nutty Crunch: That whole wheat sourdough starter? It’s the flavor bomb. The crust gets a satisfying crunch, while the inside stays soft with a subtle tang—like a hug from your favorite baker. (Yes, even my picky husband doesn’t skip seconds.)
- Weeknight Hero: This bread is my go-to for sandwiches, toast, or even croutons—no fancy prep, just slice and serve. The 50% whole wheat ratio keeps it hearty, so it’s perfect for lunchboxes or a quick charcuterie board when you’re running late.
- Budget-Friendly Staple: A single batch lasts my family five days, and I’m not exaggerating. The whole wheat flour adds fiber, the starter stretches ingredients, and the salt balances everything—meaning fewer store-bought loaves draining my wallet. Plus, it freezes like a dream.
Step-by-step instructions for 50 whole wheat sourdough bread
Precision and patience yield a loaf with deep nutty flavor and open crumb structure.
Feed and Prepare the Sourdough Starter
Combine the 1.5 cups active whole wheat sourdough starter with 2 cups unbleached white bread flour (for starter feed) and 0.5 cup honey (for starter feed) in a clean bowl. Mix until fully incorporated, then cover loosely with a damp towel. Let ferment at 75°F for 4-6 hours until it shows 50-75% increase in volume and exhibits bubbly, domed activity at the surface.
This feeding jumpstarts fermentation and ensures your starter is at peak activity before mixing with the dough. The honey provides quick energy for the yeast while the white flour boosts gluten development. If bubbles appear unevenly, gently stir to redistribute the starter before proceeding.
Mix the Dough with Hydration Control
In a large mixing bowl, combine 25 lbs King Arthur bread flour (whole wheat) and 2.5 lbs unbleached all-purpose flour. Create a well in the center and add 2.5 tbsp diamond crystal kosher salt and 0.5 cup extra-virgin olive oil. Gradually add 20.25 cups distilled water while mixing with a dough whisk until a shaggy mass forms.
Add the fed starter and mix until fully incorporated. The dough should feel sticky but manageable—this high hydration (80%) creates an open crumb but requires careful handling. Use a silicone spatula to scrape down the sides and fold the dough over itself 3-4 times to develop gluten. The dough should pull away from the bowl sides with slight resistance.
Bulk Ferment with Stretch-and-Folds
Cover the bowl with a damp towel and let ferment at 75°F for 4-6 hours. Perform stretch-and-folds every 30 minutes during the first 2 hours: wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl 90° between each fold to ensure even gluten development.
You'll know the dough is ready when it shows 30-50% volume increase and exhibits jiggly, aerated texture with large bubbles forming. The dough should pass the "poke test"—when you press a finger into the dough, it should spring back slowly (not immediately) and leave a noticeable indentation. This indicates proper gluten structure and fermentation.
Shape and Final Proof
Lightly dust a clean work surface with 2 cups cornmeal (for dusting). Turn out the dough and gently shape it into a tight round using the "stretch-and-roll" method: stretch one section of dough toward you while rolling it into the center. Repeat until all edges meet, creating surface tension. Place seam-side down on the prepared surface.
Cover loosely and let proof at 75°F for 1-2 hours until the dough rises 50-75% and shows visible bubbles along the surface. For the final shape, brush the dough with 0.5 cup ice water (for final shape) and gently shape into an oval loaf. This creates steam during baking for a crisp crust.
Bake in the Dutch Oven
Preheat the Dutch oven (or baking stone) in a 475°F oven for 1 hour. Line the bottom with 1 sheet baking parchment paper and carefully transfer the shaped dough onto it. Score the top with a sharp razor in a ½-inch deep crosshatch pattern to control expansion and create an appealing crust.
Bake covered for 20 minutes, then remove the lid and bake uncovered for an additional 25-30 minutes until the internal temperature reaches 205-210°F and the crust develops a deep golden brown color. The bread should sound hollow when tapped on the bottom. Cool on a wire rack for at least 2 hours before slicing to allow the crumb to set properly.
Pro Tips For Making 50 Whole Wheat Sourdough Bread
- Mix by Weight: Forget volume measurements for the flours—this recipe needs precision. King Arthur’s whole wheat flour is denser than AP, and guessing leads to dry dough or gummy bread. Use a kitchen scale for the 300g whole wheat and 200g AP (yes, even if the recipe says "about"). I learned this the hard way when my first batch turned out like a brick.
- Hydrate the Starter: Your whole wheat starter drinks more than white. If it’s thick and stubborn, add 10–15g extra distilled water to the 50g starter weight called for—whole wheat absorbs faster and can leave your dough dry. Test by pinching: if it springs back too slowly, it’s thirsty.
- Skip the Over-Kneading: Whole wheat dough resists like a stubborn mule. Stop when you hit the "windowpane test" (stretch a bit—it shouldn’t tear immediately) and let the gluten develop during bulk fermentation. Overwork it, and you’ll end up with a chewy, dense loaf instead of that light, airy crumb you’re after.
- Steam the First 10 Minutes: Whole wheat crusts burn before they brown. Boil a kettle, pour ½ cup water into a tray on the oven floor, and close the door for the first 10 minutes at 425°F. This gives you a crispy crust without charring—trust me, your future toast will thank you. (And yes, even if you’re impatient like me.)
Dietary considerations for these flavors
Gluten-Free Adaptations
Whole wheat sourdough is naturally gluten-heavy, but for those with gluten sensitivities, you can adapt this recipe using a gluten-free flour blend like King Arthur Measure for Measure.
Replace the whole wheat and all-purpose flours with 27.5 lbs of the blend and add 1 tbsp xanthan gum to mimic gluten’s structure. Expect a denser crumb—hydrate at 70% instead of 75% and proof for 10-15% longer to compensate for slower fermentation. 🌾
Nut-Free Options
While whole wheat contains natural gluten, some bakers avoid nuts due to allergies. If you’re concerned about cross-contamination, use certified nut-free flours like Bob’s Red Mill Organic Whole Wheat Flour.
For added safety, bake in a dedicated oven or clean all surfaces thoroughly. The flavor remains identical, but the texture will be slightly lighter without nut-based additives.
Lower Sodium Adjustments
This recipe’s 2.5 tbsp kosher salt enhances flavor and controls yeast activity. For lower sodium, reduce to 1.5 tbsp and compensate with 1 tbsp nutritional yeast (adds umami depth). Monitor fermentation closely—lower salt levels can cause slower rise times.
Taste the dough before final proofing; if bland, add a pinch more salt or a splash of apple cider vinegar for tang.
Diabetic-Friendly Modifications
To lower glycemic impact, replace 5 lbs of whole wheat flour with 5 lbs almond flour (blended fine) and 2.5 lbs coconut flour (high fiber). Increase water to 21 cups—coconut flour absorbs aggressively.
Ferment at 70°F for 6-8 hours (longer fermentation reduces sugar content). The result is a sweeter, denser loaf with improved blood sugar response. 💫
Allergen-Free Storage
Store finished loaves in airtight containers lined with parchment paper to prevent cross-contamination. For gluten-free or nut-free versions, label containers clearly. Freeze individual slices wrapped in plastic wrap—thaw at room temperature for 30 minutes before toasting.
Avoid metal utensils when serving to those with nickel allergies; use stainless steel or ceramic tools instead.

Frequently asked questions
Why does whole wheat sourdough need extra hydration compared to white flour?
Whole wheat flour absorbs 20-30% more water than white flour due to its bran content, which acts like a sponge. The recipe uses 75% hydration (vs. 65-70% for white flour) to create that signature open crumb while preventing dryness. Too little water = dense loaf; too much = sticky mess.
Can I make this recipe without a Dutch oven?
Yes! Use a baking stone preheated to 475°F with a steam pan underneath. Place the dough on parchment-lined stone, then pour 1 cup boiling water into the pan when loading the oven. This mimics the steam effect for 20 minutes covered. The crust won't be as crispy but still delicious.
How do I know when the starter is ready for mixing?
Your starter should show 50-75% volume increase with bubbly, domed activity when poked. It should smell sweet-tangy (like yogurt or vinegar) and float in water. If it's sluggish, feed it again for 2 more hours at 75°F. Never use a flat, sour-smelling starter—it'll ruin your dough.
What's the best way to handle sticky dough for 50 servings?
Wet your hands with water at 85°F (not cold) and dust your work surface with 2 cups cornmeal. Use a bench scraper to lift and fold dough rather than pressing it. For shaping, divide into 10 batches—work with one at a time to prevent drying. Keep unused dough covered with a damp towel.
Why did my bread turn out dense instead of light?
Three likely causes: underproofed dough (needs 4-6 hours bulk fermentation), too little hydration (stick to 75% for whole wheat), or overmixed dough (fold gently, don't knead). For next time, check the "poke test"—dough should spring back slowly (not immediately). If still dense, try adding 1 extra tablespoon of olive oil to the dough.
