Holzofenbrot is a rustic sourdough optimized for high, variable heat from a wood-fired oven. It combines a strong open crumb, blistered crust, and smoky notes when baked on hot stone or in a hearth. Long fermentation and careful temperature control produce flavor and digestibility while maintaining oven spring.[1][2]

Ingredients

Weigh all ingredients on a kitchen scale. For wood-fired baking, aim for a slightly stronger dough (higher protein) and moderate hydration to tolerate intense oven heat.[1]

Ingredient Amount % Note
Strong bread flour (high-protein) 700g 100% gives structure for oven spring
Whole wheat flour 150g 21% adds flavor and color
Water 520g 74% room temp; adjust ±10g based on flour absorption
Active sourdough starter 140g 20% refreshed and bubbly
Salt 18g 2.6% for taste and dough strength
Optional: Smoked sea salt 2g 0.3% small boost to 'wood-fired' aroma

Schedule

Traditional Long (recommended)

Maximizes flavor and makes timing flexible for wood-fired ovens

Day 1 morning Feed starter to peak
Day 1 afternoon Autolyse: mix flours and water, rest 45-60 min (45-60 min)
Day 1 afternoon Mix with starter and salt, perform stretch-and-folds over 2 hours (2 hours)
Day 1 evening Bulk fermentation until ~30–50% rise (3–4 hours at 22°C)
Day 1 late evening Shape and place in [banneton](https://amzn.to/4sNHBYO), then retarded proof in fridge (12–24 hours)
Day 2 baking time Bake in wood-fired oven or home oven / Dutch oven (40-60 min)

Single-day (when kiln hot)

Shorter timeline for experienced bakers who can match oven heat

Morning 6am Feed starter
Morning 10am Mix, autolyse, and bulk ferment (4–5 hours)
Afternoon 3pm Shape, short proof
Evening 6pm Bake in hot oven/hearth

💡 Tips

  • If your hearth is cooler than expected, extend proofing to increase oven spring potential[1].
  • Retarding dough in the fridge improves flavor and makes baking windows flexible[2].

Step by Step

1

Autolyse

In a large mixing bowl combine flours and water until no dry patches remain. Rest 45–60 minutes. Autolyse improves gluten development and hydration—especially helpful before subjecting the dough to variable wood-oven heat.[1][2]

✓ Visual check: Surface smooths, dough feels cohesive
⚠️ Common mistake: Skipping autolyse reduces extensibility and oven spring

⏱ 45-60 minutes

2

Mix and develop

Add starter and salt. Mix using a dough scraper and gentle pinches until integrated. Perform 4–6 sets of stretch-and-folds every 20–30 minutes during bulk fermentation to build strength without overworking.[1]

✓ Visual check: Dough gains elasticity, shows bubbles
💡 Keep dough at 21–24°C for steady fermentation

⏱ 2–3 hours (including folds)

3

Bulk fermentation

Allow dough to rise until ~30–50% volume increase. For wood-fired ovens a slightly under-fermented dough often gives better oven spring because the high heat finishes the expansion.[2]

✓ Visual check: Bubbles on surface and sides, dough jiggles

⏱ 3–5 hours (depends on temp)

4

Shape

Turn dough onto lightly floured surface, pre-shape into a tight boule or bâtard using a dough scraper. Final shape should be tight to trap gases. Place seam-side up in a floured banneton.

✓ Visual check: Taut surface and defined seam

⏱ 10 minutes

5

Cold proof (recommended)

Retard in the fridge 12–24 hours to develop flavor and make baking schedule flexible. Cold dough is easier to handle when loading into a hot oven or hearth.[1]

✓ Visual check: Dough slightly risen, very chilled

⏱ 12–24 hours

6

Prepare oven/hearth

If using a wood-fired oven, ensure the hearth and stone are heated evenly—aim for 350–400°C surface then rake coals aside to create a hot floor with lower dome heat. For home ovens, preheat a Dutch oven at 260–275°C (500–525°F) for 45–60 min to mimic hearth conditions.[1][2]

✓ Visual check: Hot stone with stable retained heat, thermometer reads target
💡 Use an instant-read thermometer to check stone and dome temps

⏱ 45–60 minutes

7

Load and bake

Turn dough onto parchment paper or peel. Score with a bread lame. For hearth: slide loaf onto hot stone, close door quickly; add a few dampened embers or a tray of water to increase steam briefly. For home ovens in a Dutch oven, bake covered 20 minutes, then uncover and reduce temp to 230°C (450°F) for remaining 20–30 minutes until crust is deeply colored.[1][2]

✓ Visual check: Strong oven spring, blistering crust, hollow thud when tapped

⏱ 40–60 minutes

8

Cool before slicing

Transfer with oven mitts to a rack and cool thoroughly. Cutting too early yields a gummy crumb—allow at least 2 hours for large loaves.[1]

✓ Visual check: Loaf no longer warm, crumb set

⏱ 2+ hours

Tips & Variations

Variations

Smoked crust

Brush loaf lightly with water and briskly expose to embers for a minute

→ Adds subtle smoky notes; practice caution with flames

Olive and rosemary

Fold 120g chopped olives and 10g fresh rosemary during shaping

→ Mediterranean flavor that withstands high heat

Hydration boost

Increase water by 10–20g for a more open crumb

→ Slightly more open crumb but harder to handle in hearth

Pro Tips

  • 💡 Use a digital kitchen scale for reproducible results; small weight changes matter in large loaves[1].
  • 💡 When transferring to a hearth, dust the peel lightly with semolina for quick release.
  • 💡 If baking in a wood oven, observe how your oven loses heat after opening and adapt loading order accordingly[2].

Common Issues

Common wood-fired problems and fixes:

Storage

Bread box/bread bag

3-5 days

Store whole and cut side down to retain moisture

Kitchen towel

2-3 days

Wrap in linen to allow some breathability

Freezing

3 months

Slice before freezing for easy use

⚠️ Don't store in the fridge—staling accelerates due to starch retrogradation; freezing is preferable for long-term storage[2].
