Yield
1 loaf (approx. 900-1000g)

Mischbrot Fünfkorn is a balanced mixed-grain sourdough that combines wheat and rye with three whole grains/seeds for texture and aroma. Long, controlled fermentation improves digestibility and flavor while allowing the mixed flours to develop structure.[1] Use a mature starter and weigh ingredients for consistent results.[2]

✓ Five-grain texture with open crumb and seed crunch ✓ Flexible schedule: overnight final proof option ✓ Uses stretch-and-folds rather than intensive kneading

Ingredients

Weigh all ingredients on a kitchen scale. Accurate hydration and ingredient ratios matter with mixed flours to predict dough behavior.[1][2]

Ingredient Amount % Note
Bread flour 300g 60% Provides gluten for structure
Medium rye flour 100g 20% Adds flavor and moist crumb
Whole spelt flour 50g 10% Adds sweet, nutty note
Barley flakes (coarsely rolled) 25g 5% Soak with water for 30 min if desired
Oats (rolled) 25g 5% For crumb texture
Water (total) 360g 72% Adjust +/- 10g depending on flour absorption
Active starter (100% hydration) 120g 24% Well-fed, bubbly starter
Salt 10g 2% Fine sea salt
Mixed seeds (sunflower, flax, pumpkin) 60g 12% Optional: toast for deeper flavor

Schedule

Classic Weekend

Start in the morning, bake in the afternoon.

Day 0 7am Feed starter
Day 0 11am Autolyse: mix flours and water (30 min)
Day 0 11:30am Add starter and salt, mix (10 min)
Day 0 11:40am-5:00pm Bulk fermentation with 3 sets of stretch-and-folds every 30 min initially
Day 0 5:00pm Shape and final proof (1.5-2 hours at room temp)
Day 0 7:00pm Bake (50-65 min)

Weekday Evening Mix / Morning Bake

Mix at night, retard in fridge, bake next morning.

Evening 9pm Mix through final shape (30 min)
Evening 9:30pm Place shaped loaf in fridge for overnight proof (8-14h)
Next day 7am Preheat oven with [Dutch oven](https://amzn.to/4sVhKhN) inside, score and bake (50-65 min)

💡 Tips

  • If fermentation runs fast, move dough to fridge to slow activity and build flavor [1]
  • Shaped dough can be kept up to 48h in the fridge; this increases sourness and aroma [2]

Step by Step

1

Prepare autolyse

Combine bread flour, rye, spelt, oats and barley flakes with 330g of water in a large mixing bowl. Mix until no dry flour remains. Rest 30 minutes to hydrate flours and begin enzymatic action.[1]

✓ Visual check: Dough mass appears cohesive and hydrated
⚠️ Common mistake: Skipping autolyse leads to stiffer dough and less flavor development

⏱ 30 minutes

2

Add starter and salt

Add active starter and remaining water if needed, then salt. Mix with a dough scraper and hand-fold until incorporated. Dough should feel tacky but manageable.[2]

✓ Visual check: Starter fully distributed, dough slightly elastic

⏱ 8-10 minutes

3

Bulk fermentation with folds

Perform 3 sets of stretch-and-folds at 30-minute intervals during the first 2 hours. After folds, let dough rest until it has risen ~30-50% and shows bubbles. Cover the bowl with a lid or cloth.

✓ Visual check: Surface shows bubbles and slight increase in volume

⏱ 3-5 hours depending on temperature

4

Incorporate seeds

Add mixed seeds during a fold so they distribute without degenerating the dough. Use wet hands to prevent sticking.

✓ Visual check: Seeds distributed through crumb
💡 Toast seeds 6-8 min at 160°C/320°F for more aroma

⏱ 2 minutes

5

Shape

Turn dough onto a lightly floured surface using a dough scraper. Pre-shape gently, rest 10-15 min, then final shape into bâtard or boule. Place seam-side up in a floured banneton or linen-lined basket.

✓ Visual check: Surface tension visible on the shaped loaf

⏱ 10-15 minutes

6

Final proof

Proof at room temperature until the loaf shows slow spring-back on the poke test or retard in fridge for 8-14 hours for flavor depth.[1][2]

✓ Visual check: Loaf increases in size and holds shape when gently pressed

⏱ 1.5-2.5 hours at room temp or 8-14 hours in fridge

7

Bake

Preheat oven to 250°C/480°F with your Dutch oven inside for 30-45 minutes. Turn loaf onto parchment paper, score with a bread lame and place into the preheated pot. Bake 20 min with lid on, then remove lid and reduce to 200°C/400°F for 25-35 min until crust is deep brown. Verify internal temperature with an instant-read thermometer: aim for 96-98°C (205-208°F).[1][2]

✓ Visual check: Deeply colored crust and hollow sound when tapped

⏱ 45-60 minutes

8

Cool

Remove from oven with oven mitts and cool on a rack at least 2 hours. Cutting earlier leads to gummy crumb because starches haven't set.[1]

✓ Visual check: Loaf is cool to the touch

⏱ 2+ hours

Tips & Variations

Variations

Honey & malt

Add 1 tbsp honey and 1 tbsp barley malt syrup

→ Adds sweetness and deeper crust color

More whole grain

Increase spelt and rye by 50g combined

→ Denser crumb, more flavor

Seed-crusted

Brush loaf with water and press seeds onto surface before bake

→ Crunchy seeded crust

Pro Tips

  • 💡 Weigh ingredients with a kitchen scale for repeatability [2]
  • 💡 Use a dough whisk for quick mixing of flours and water during autolyse
  • 💡 Slice with a serrated bread knife after 24 hours for best crumb development

Common Issues

If outcomes are off, check these common causes:

Storage

Bread bag or box

4-6 days

Store whole loaf; slice as needed

Kitchen towel

3-4 days

Wrap in linen to maintain crust while preventing condensation

Freezing

3 months

Slice before freezing and toast slices directly from frozen

⚠️ Avoid refrigeration; it accelerates staling through starch retrogradation and dries crumb faster [2]
