At a Glance
Frankenlaib is a regional German rye-sourdough loaf: moderately sour, slightly moist crumb and a firm crust. It relies on a long, cool fermentation to develop flavor and shelf stability; traditional techniques emphasize hydration control and minimal handling to preserve the rye structure[1][2].
Not suitable if:
- • You prefer light, airy wheat loaves → try a wheat sourdough
- • You don't have an active rye starter → create a rye starter first

Ingredients
Weigh all ingredients on a kitchen scale; rye is sensitive to hydration and small errors change the crumb significantly[2].
| Ingredient | Amount | % | Note |
|---|---|---|---|
| Medium rye flour | 500g | 83% | German Type 1150 preferred for authentic texture |
| Bread flour | 100g | 17% | Adds gluten support for a slightly more open crumb |
| Water | 420g | 70% | Cool water (18-22°C) for better fermentation control |
| Active rye starter | 150g | 25% | Feed 8-12h before use and ensure active bubbling[1] |
| Salt | 12g | 2% | Fine sea salt |
| Caraway (optional) | 6g | 1% | Traditional flavor in some Franken versions |
Schedule
Traditional (long cold ferment)
Builds depth of flavor with overnight retard
Quick weekend
Shorter timeline for weekend baking
💡 Tips
- If fermentation is too fast, move shaped dough to the fridge to slow it (retardation leverages cold to control acidity and gas production)[1]
- Shaped loaves can be kept up to 48h refrigerated; factor in oven time when planning
Step by Step
Autolyse and mix
Combine flours and water in a large mixing bowl. Let rest 20-40 minutes (autolyse) to hydrate the rye and develop viscosity. Add starter and salt, then mix until homogeneous using a dough scraper or a wooden spoon. Avoid overworking—the goal is even hydration, not gluten development like wheat loaves[2].
⏱ 20-40 minutes (including autolyse)
Bulk fermentation
Cover bowl with a towel or lid. Allow bulk fermentation at 18-22°C until dough increases slightly and shows small bubbles — typically 3-5 hours depending on starter activity[1].
⏱ 3-5 hours
Pre-shape and rest
Gently turn dough onto a floured surface (use rye flour) using a dough scraper. Pre-shape into a loose oval; rest uncovered 20 minutes to relax.
⏱ 20 minutes
Final shape
Shape into the traditional round or oblong Franken form. Dust a banneton with rye flour and place seam-side up. The shaping is gentle — avoid degassing the dough.
⏱ 10 minutes
Cold proof (recommended)
Cover and refrigerate for 12-18 hours. Cold proof enhances flavor and firms the crumb for cleaner slicing; it also helps control final oven spring[1][2].
⏱ 12-18 hours
Bake
Preheat oven to 250°C/480°F with a Dutch oven inside for 30-45 minutes. Turn loaf onto parchment paper, score with a bread lame, and transfer to the Dutch oven. Bake covered 15-20 minutes, then remove lid and reduce temp to 200°C/400°F for 30-40 minutes until crust is deeply colored. Check internal temp with an instant-read thermometer: 96-98°C / 205-208°F indicates done[1].
⏱ 50-65 minutes
Cool long
Remove loaf with oven mitts and cool on a rack for at least 2 hours. Cutting too early yields a gummy crumb because rye starches need time to set[2].
⏱ 2+ hours
Tips & Variations
Variations
Caraway-forward
Increase caraway to 10g and toast briefly
→ Stronger regional aroma
With seeds
Add 50g mixed seeds (sunflower, flax)
→ Extra texture and shelf-life
Lean modern
Replace 50g rye with whole wheat for milder flavor
→ Smoother crumb, less dense
Pro Tips
- 💡 Always measure on a kitchen scale — rye hydration is unforgiving[2]
- 💡 Score shallowly on rye loaves; deep slashes can collapse the loaf
- 💡 Slice the loaf the next day with a serrated bread knife for clean slices
Common Issues
Common problems with Frankenlaib and quick fixes:
Storage
Bread box/bread bag
5-7 days
Keep whole loaf; cut side down to retain moisture
Kitchen towel
3-4 days
Use linen to avoid trapping moisture
Freezing
3 months
Slice and vacuum or wrap before freezing; thaw at room temp
⚠️ Avoid storing in the fridge — staling accelerates due to starch retrogradation[2].
