Ingredients for 50 whole wheat sourdough bread
Fifty loaves of nutty, crusty whole wheat sourdough begin with these precise ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | 16 oz | 100% hydration, fed and bubbly |
| Whole Wheat Flour 🌾 | 20 lbs | High-protein, freshly milled preferred |
| All-Purpose Flour 🌾 | 5 lbs | For structure and handling |
| Granulated Sugar 🍚 | 1 ½ cups | Feeds yeast during fermentation |
| Unsalted Butter 🧈 | 2 cups | Cold, cubed for optimal hydration |
| Large Eggs 🥚 | 10 whole | Room temperature for even mixing |
| Instant Yeast 🍞 | 1 ½ tbsp | Ensures reliable rise at scale |
| Sea Salt 🧂 | 4 tbsp | Diamond Crystal preferred |
| Water 💧 | 12 cups | Room temperature, filtered preferred |
| Cornmeal 🌽 | 1 cup | For dusting dough and baking surface |
| Ice Cubes ❄️ | 2 cups | For dough chilling between stages |
| Dried Milk Powder 🥛 | ½ cup | Enhances flavor and texture |
| Honey 🍯 | ¼ cup | Feeds starter and adds sweetness |
The sourdough starter is the foundation—King Arthur or Bob's Red Mill brands yield reliable results at this scale. Aim for a 100% hydration starter with visible bubbles and a tangy aroma. If sourcing flour, White Lily or Caputo whole wheat flours provide the best balance of nutrition and texture. The butter should be European-style for higher fat content, which improves crumb softness. For the eggs, organic pastured ensures richer flavor, though conventional works fine. The instant yeast is critical for consistent rise—Red Star is the gold standard in professional kitchens. Diamond Crystal sea salt dissolves more slowly, enhancing flavor development during fermentation.
Substitutions require precision at this scale. No whole wheat flour? King Arthur Multigrain works in a pinch, though texture will differ slightly. Butter shortages? Coconut oil can replace up to 50% of the fat, though flavor will be subtly altered. Egg allergies? Flax eggs (1 tbsp ground flax + 3 tbsp water per egg) maintain structure. For the honey, maple syrup is a 1:1 substitute, though fermentation timing may vary slightly. The dried milk powder can be omitted if unavailable, but expect a marginally less tender crumb. Bread flour may replace all-purpose flour for improved oven spring, though whole wheat content will decrease.
Store starter in an airtight jar at room temperature, feeding daily with equal parts flour and water. The dough can be refrigerated for up to 24 hours before final proofing, though flavor peaks at room temperature. Baked loaves develop full flavor after 2-3 days at room temperature, wrapped in a clean kitchen towel. For long-term storage, freeze fully cooled loaves for up to 3 months—thaw at room temperature for 1-2 hours before slicing. Slicing with a serrated knife ensures clean cuts through the dense crumb structure.

Step-by-step instructions for artisan whole wheat sourdough
This method delivers professional-level sourdough with a crisp crust and open crumb.
Prepare the Autolyse for Optimal Hydration
In a large mixing bowl, combine the 20 lbs whole wheat flour and 12 cups water. Use a dough whisk to break up any flour clumps and create a shaggy dough. The goal is to hydrate the flour completely before adding other ingredients - this is called an autolyse. Let the mixture rest for 30 minutes at room temperature while you prepare the remaining components.
During this time, the flour will begin to absorb moisture and develop gluten strands. You'll notice the dough becomes more cohesive and elastic. This resting period is crucial for developing the gluten structure needed to support the bread's rise and create that signature open crumb.
Incorporate Leaveners and Fat for Structure
After the autolyse, add the 16 oz active sourdough starter, 1.5 tbsp instant yeast, 1.5 cups granulated sugar, 2 cups cold cubed unsalted butter, 10 whole large eggs, and 0.5 cup dried milk powder to the dough. Using a stand mixer with a dough hook attachment, mix on low speed for 5 minutes until all ingredients are fully incorporated and the dough begins to come together.
This is where the magic happens - the combination of high-protein whole wheat flour and all-purpose flour creates the perfect balance of structure and extensibility. The cold butter will begin to incorporate gradually, creating pockets that will contribute to the bread's texture. Mix until the dough reaches a smooth, elastic consistency that pulls away from the sides of the bowl.
Develop Gluten Through Kneading and Resting
Continue kneading on medium speed for 8-10 minutes until the dough reaches 110°F internal temperature. The dough should be smooth, elastic, and slightly tacky but not sticky. If it's too sticky, add 1-2 tablespoons of the 5 lbs all-purpose flour as needed to achieve proper handling consistency.
Once kneaded, transfer the dough to a lightly oiled mixing bowl. Cover with a damp towel and let it rest at room temperature for 1 hour. This resting period allows the gluten to relax and redistribute, making the dough easier to handle during shaping. The dough should increase slightly in volume during this time, indicating proper gluten development.
Bulk Fermentation for Flavor Development
After the initial rest, divide the dough into 50 equal portions (approximately 8 oz each). Shape each portion into a tight round boule by pulling the dough toward the center and tucking the edges underneath. Place the shaped boules on a baking sheet dusted with 1 cup cornmeal, cover with a damp towel, and refrigerate for 12 hours or overnight.
Cold fermentation slows yeast activity, allowing for better flavor development and gluten relaxation. The dough should increase in volume by about 25% during this time. This cold proof is particularly important for whole wheat doughs, which can be more challenging to handle due to their higher protein content and natural acids.
Final Proof and Baking for Crusty Texture
Remove the dough from the refrigerator and let it come to room temperature for 1 hour. Preheat your oven to 450°F with a baking stone or inverted baking sheet inside. Place a metal bowl filled with boiling water on the lower oven rack to create steam.
Transfer the boules to the preheated baking stone. Score the top of each boule with a sharp razor blade in a crosshatch pattern. Bake for 25-30 minutes until the crust is deep golden brown and the internal temperature reaches 205°F. Rotate the baking sheet halfway through baking for even color development.
Pro Tips For Making 50 Whole Wheat Sourdough Bread
- Hydrate the Wheat: Whole wheat flour soaks up moisture like a sponge—don’t skimp on water. I used to eyeball it and ended up with a stiff, dry dough that refused to rise. Aim for 1/3 cup more water than the recipe calls for (about 300-320g total for 50g starter + 350g whole wheat flour), then adjust as you go. The dough should stick to your fingers but not be gluey.
- Feed Your Starter Early: A hungry starter won’t perform. The night before baking, do a 24-hour feed cycle—discard half, then feed it equal parts whole wheat flour and water (e.g., 50g starter + 50g flour + 50g water). By morning, it’ll be bubbly and ready to bulk ferment, giving your bread that reliable rise. (Yes, it’s extra work, but skipping this is how you end up with a pancake.)
- Skip the Over-Kneading: Whole wheat dough is stubborn—it won’t stretch like all-purpose. Instead of punching and folding until your arms give out, do 3-4 sets of 30-second stretches during bulk fermentation. Overworking it develops too much gluten, making the crumb dense. Let the sourdough’s natural elasticity do the work.
- Butter the Pan Cold: That unsalted butter isn’t just for flavor—it’s your crust’s best friend. Brush a thin, even layer over the pan after shaping but before proofing, then chill the dough for 30 minutes. The cold butter melts slower in the oven, creating a shatteringly crisp bottom without burning. (Pro move: Use a pastry brush to avoid globs.)
Make-ahead tips for 50 whole wheat sourdough bread
Pre-Ferment Prep
Mix your starter the night before to save time—feed 16 oz with 16 oz whole wheat flour and 16 oz water at 7:00 PM. By morning, it’ll be ready for peak activity.
I store mine in a glass jar with a loose lid to allow gas escape. This overnight prep ensures your dough starts with maximum leavening power, cutting your morning work in half. 🌱
Dough Portioning Hack
Weigh dough portions using a digital scale (like the OXO Good Grips) for precision. For 50 servings, divide into 8 oz balls—this ensures consistent baking. I use a dough scraper to cleanly separate pieces, preventing sticking.
Label each portion with the time to track proofing progress. This method guarantees uniform rise and bake times. ✨
Cold Proofing Advantage
Refrigerate shaped boules overnight for 12 hours—this slow fermentation develops deeper flavor and easier handling. I wrap dough in plastic wrap and place it in a large cooler to maintain consistent temperature.
The cold slows yeast activity, preventing overproofing while allowing gluten to relax. This step is especially critical for whole wheat doughs that can become gummy. 🥶
Baking Efficiency
Preheat your oven with a baking stone (like Great Jones) and place a metal bowl of boiling water on the lower rack for steam. Bake two trays simultaneously by rotating pans halfway through—this maximizes oven space and ensures even browning.
I use a laser thermometer to monitor internal temp at 205°F. This batch-and-rotate method cuts baking time by 20% for large batches. 🔥
Storage Solutions
Cool loaves completely on a wire rack before storing. For short-term use (3 days), wrap in a clean kitchen towel and place in a bread box. For longer storage, freeze fully cooled loaves in ziplock bags with all air removed.
Thaw at room temperature for 2 hours before slicing. This method preserves freshness and texture for up to 3 months. ❄️
Make-Ahead Timeline
Plan ahead with this 24-hour schedule:
- Day 1 (Evening): Feed starter, mix dough, and begin autolyse
- Day 2 (Morning): Complete mixing, divide portions, and refrigerate
- Day 2 (Evening): Final proof and bake
This staggered approach prevents last-minute stress while ensuring optimal flavor development. 📅
Nutrition facts
Frequently asked questions
Why does whole wheat sourdough need a longer fermentation time?
Whole wheat flour contains natural acids and bran that slow yeast activity, requiring extended fermentation. The 12-hour cold proof enhances flavor development and gluten relaxation, creating a lighter crumb. This process also improves digestibility by breaking down phytic acid in the whole grains.
Can I substitute all-purpose flour for whole wheat in this recipe?
Yes, but expect a denser texture and less nutty flavor. Replace up to 50% of the whole wheat flour with all-purpose flour for easier handling, though the nutritional benefits will decrease. For best results, use King Arthur Multigrain flour as a compromise.
How do I know when the dough is properly proofed?
Press gently on the dough—if it springs back slowly (not immediately) and leaves a slight indentation, it's ready. For whole wheat, look for 25% volume increase during cold proof. Overproofing is harder to detect but results in flat loaves. Use a timer to track 12 hours of cold proofing.
What's the best way to store freshly baked whole wheat sourdough?
Cool completely on a wire rack, then wrap in a clean kitchen towel and store in a bread box at room temperature for 2-3 days. For longer storage, freeze wrapped loaves for up to 3 months. Thaw at room temperature before slicing to preserve texture.
Can I make this recipe without a stand mixer?
Use a dough whisk for mixing and knead by hand for 15-20 minutes until the dough reaches 110°F internally. The key is patience—whole wheat dough requires more effort to develop gluten. Work in short bursts to avoid overheating.
