Basic Mixed Sourdough (Grundrezept Mischbrot) — Beginner Friendly

A forgiving mixed wheat-rye sourdough loaf for beginners. Step-by-step, with practical tips and troubleshooting to build foundational skills.

What to Expect

This basic mixed sourdough deliberately prioritizes learnability and flavor over artisan theatrics. Expect a reliably tasty loaf that teaches you fermentation timing, dough feel and basic shaping.

What you'll learn:

  • ✓ How a wheat–rye blend changes dough behavior
  • ✓ How to judge readiness after bulk fermentation and proof
  • ✓ How refrigeration extends flexibility and reduces mistakes

💭 Your first loaves will teach you most — shape, crumb and oven-spring improve quickly with a few bakes. Focus on reproducibility rather than perfect aesthetics.

What You Need

Must have:

Active sourdough starter

Bubbly and active 4–8 hours after feeding, shown in a starter jar

⚠️ Create a starter first → more

Kitchen scale

Accurate to the gram — sourdough is a baker's math

⚠️ Buy one before you start; weight-based recipes are consistent

Dutch oven

Oven-safe to 480°F / 250°C

Alternative: If you don't have one, a hot baking sheet plus a pan of water will create steam.

Nice to have:

Why this recipe is forgiving:

Moderate hydration (65%)

Lower hydration reduces stickiness and makes shaping easier for beginners [1].

Wheat–rye blend

Rye adds flavor and tolerance; mixed flours tolerate wider fermentation windows than straight white doughs [2].

Cold retard (refrigerator proof)

Slows fermentation so timing is flexible and over-proofing is less likely, a common beginner advantage [1].

Loaf pan option

Using a pan removes most shaping failures; you still learn fermentation and baking fundamentals [2].

Ingredients

For: 1 bread (about 1.75 lbs / 800g)

Bread flour 350g
Medium rye flour 100g Adds flavor and retains moisture
Water 290g Lukewarm, about 85°F / 30°C — temperature affects fermentation speed [1]
Active sourdough starter 100g Use when it's peaked and active 4–8 hours after feeding [1]
Salt 9g About 2 tsp; always weigh for consistency

Step by Step

Mix in evening → Refrigerate overnight → Shape and bake next day

1

Mix dough (Evening, 10 min)

9:00 PM

Weigh all ingredients on your kitchen scale into a large mixing bowl. Stir with a spoon or a dough whisk until no dry spots remain.

✓ Homogeneous, slightly tacky dough
💡 No formal kneading required for this hydration — mixing develops enough structure for the overnight rest [1].
2

Autolyse / short rest (30 min)

9:00–9:30 PM

Cover bowl and let rest. This hydrates flour and begins gluten development.

✓ Dough looks smoother and more extensible [2]
3

Add salt and fold (2 min)

9:30 PM

Sprinkle salt and gently incorporate. Perform 4 stretch-and-folds at ~10–15 minute intervals or do 4 folds now.

✓ Dough gains slight strength and surface tension
→ Stretch and Fold technique
4

Bulk rest and refrigerate

10:00 PM

Cover bowl (plastic wrap or lid) and place in refrigerator. Cold retard for 12–20 hours to develop flavor and slow fermentation.

✓ Dough is relaxed and slightly risen; bubbles visible under the surface [1]
5

Turn out and shape (Next day afternoon/evening)

Afternoon/Evening

Use a dough scraper to turn chilled dough onto a lightly floured surface. For freeform: do letter folds to create tension and shape into a tight boule. For an easier option, press into a greased loaf pan.

✓ Surface appears taut; seam holds
💡 Beginners: a loaf pan reduces shaping errors and still produces good crumb [2]
6

Second proof (1–2 h)

Place shaped loaf seam-up in a floured proofing basket or seam-down in pan. Rest at room temperature until slightly puffy; use the poke test — slow spring back indicates readiness [1]

✓ Loaf passes poke test
7

Preheat oven

Preheat oven with your Dutch oven inside to 480°F / 250°C for at least 30 minutes so the vessel is thoroughly hot.

💡 A fully heated vessel produces the best oven-spring and crust [1]
8

Bake

Carefully transfer dough into the hot Dutch oven (use oven mitts). Cover and bake 30 minutes, then remove lid and reduce temperature to 425°F / 220°C for 20–25 minutes until crust is deep brown.

✓ Crust is dark and loaf sounds hollow when tapped; internal temperature about 200–208°F / 93–98°C [2]
💡 If using a loaf pan, bake uncovered but add steam with a water pan on the oven floor for the first 10 minutes.
9

Cool (IMPORTANT!)

Cool on a rack for at least 1 hour, preferably 2. Cooling lets the crumb set and finish starch retrogradation — slicing too early yields a gummy interior [1][2].

⚠️ Do not slice while warm.

What If It Doesn't Work?

Common issues and practical fixes:

Bread is too flat

Likely: Starter not active or dough over-proofed during bulk or final proof

Fix: Use a more active starter (feed and wait for peak) and shorten proof times; try warmer bulk and colder retard to balance activity [1]

→ More info

Gummy or underbaked crumb

Likely: Insufficient bake time or sliced too soon

Fix: Bake longer at slightly lower temp if crust darkens too quickly; always cool at least 1–2 hours [2]

→ More info

Too sour

Likely: Excessive fermentation time or too much rye/acid development

Fix: Shorten proof times, use cooler fermentation or reduce starter percentage next time [1]

→ More info

No oven-spring / loaf didn't open

Likely: Underproofed seam tension, blunt scoring, or insufficient steam

Fix: Create a tight skin during shaping, score confidently with a [bread lame](https://amzn.to/3LKDRH0) and use a covered vessel like a Dutch oven for steam [2]

💪 Even imperfect homemade sourdough usually tastes better than store bread — learn from each loaf and adjust one variable at a time [1].

What now?

That worked!
→ Try increasing hydration or more active folds for more open crumb
I want a stronger rye character
→ Experiment with higher rye percentages and different rye types
I want to shape better
→ Practice shaping techniques and tension creation
I want to understand the science
→ Read core fermentation and enzyme behavior in sourdough
