At a Glance
A traditional Mischbrot with 70% rye and 30% spelt (Dinkel). This formula balances rye's aroma and moisture with spelt's lighter crumb. Long, cool fermentation improves flavor and digestibility — a core principle in German sourdough practice[2].
Not suitable if:
- • You prefer a light, fully wheat crumb → see classic white loaf
- • You don't have an active rye-capable starter → create a starter

Ingredients
Weigh all ingredients on a kitchen scale. Rye hydration behaves differently than wheat — weigh for consistency and follow timings rather than feel alone[1][2].
| Ingredient | Amount | % | Note |
|---|---|---|---|
| Medium rye flour | 420g | 70% | German Type ~997–1150; provides the characteristic rye flavor |
| Spelt (Dinkel) flour, strong | 180g | 30% | Adds gluten support and lighter texture |
| Water | 520g | 86% | High hydration helps rye stay moist; temperature ~24°C (75°F) |
| Active rye starter (100% hydration) | 160g | 27% | Feed 6-10 hours prior so starter is active and bubbly[1] |
| Salt | 12g | 2% | Adjust to taste |
| Caraway seeds (optional) | 10g | 2% | Traditional flavor; add during mixing |

Night Prep / Weekday
Shape and retard in fridge overnight; bake next day
💡 Tips
- If dough ferments faster than planned, cool it in the fridge to slow activity — useful for temperature control[2].
- Shaped dough tolerates 12–48h in the fridge; flavor improves with time[1].
Step by Step
Autolyse & mix
Combine rye and spelt flours with most of the water (reserve ~20g). Mix in a large mixing bowl until no dry flour remains. Rest 30–45 minutes to hydrate flour and improve gluten development in spelt[1]. After autolyse, add starter, reserved water, and salt; mix with a dough scraper until homogeneous.
⏱ 35-50 minutes
Bulk fermentation
Cover bowl. Bulk ferment at 20–22°C until dough shows some doming and small bubbles. For this mix expect 4–6 hours; timing varies with starter strength and temperature[1][2]. Fold once after 60–90 minutes to organize dough and distribute gas.
⏱ 4-6 hours (variable)
Shape
Generously dust work surface with rye or spelt flour. Turn dough out using a dough scraper. Shape gently into a bâtard (oblong) — don't degas aggressively. Place seam-side up in a floured banneton.
⏱ 8-12 minutes
Final proof (room or fridge)
Cover and proof until the dough has risen and passes a gentle poke test. For room temperature proof allow 1.5–2.5 hours; for overnight retard, refrigerate 10–14 hours. Retarding increases acidity and improves shelf life[2].
⏱ 1.5-14 hours depending on method
Preheat and 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. Transfer to the Dutch oven, cover and bake 20 minutes, then remove lid and reduce to 200°C / 400°F for another 35–40 minutes until well colored. Use an instant-read thermometer to confirm internal temp 96–98°C (205–208°F)[1].
⏱ 55-65 minutes
Cool before slicing
Transfer loaf with oven mitts to a rack and cool at least 2 hours. Cutting too early makes rye crumb gummy due to retained moisture and incomplete starch set[2].
⏱ 2+ hours
Tips & Variations
Variations
Seeded Mischbrot
Add 50g mixed seeds (sunflower, flax) during mixing
→ More texture and nuttiness
Lightly Sweetened
Add 1 tbsp honey to water
→ Subtle sweetness; crust browns slightly faster
Higher Spelt Ratio
Use 40% spelt / 60% rye
→ Softer crumb, easier handling
Pro Tips
- 💡 For consistent results weigh ingredients on a kitchen scale. Precision reduces variability[1].
- 💡 Develop a rye-capable starter by feeding rye flour for several days if your starter is wheat-based[2].
- 💡 Slice with a serrated bread knife after full cooling to preserve crumb structure.
Common Issues
Not going as planned? Common issues:
Storage
Bread box/bread bag
5-7 days
Store cut side down to retain moisture
Kitchen towel
3-4 days
Use linen to allow slight airflow
Freezing
3 months
Slice before freezing; toast directly from frozen
⚠️ Don't store bread in the fridge — refrigeration accelerates starch retrogradation and makes bread stale faster[2].
