1. What Is Sourdough Bread?

Sourdough is a naturally leavened bread made using wild yeast and lactic acid bacteria from a fermented flour-water mixture called a sourdough starter. Unlike commercial yeast, this natural process yields superior texture, flavor, and nutrition.

2. Health Benefits of Sourdough

  • Lower Glycemic Index: Slow fermentation reduces sugar spikes.

  • Digestibility: Natural bacteria help break down gluten.

  • Nutrient Bioavailability: Fermentation improves mineral absorption.

  • No Preservatives: Long shelf life due to natural acidity.

3. Authentic Professional Sourdough Bread Recipe

Ingredients

IngredientBaker’s %Weight (g)Notes
Bread Flour100%1000gHigh protein (12.5–13%)
Water75%750gPreferably filtered
Sourdough Starter (100% hydration)20%200gActive and bubbly
Salt2%20gFine sea salt

Yield:

  • Two large boules or three medium bâtards

4. Method: Step-by-Step Baking Process

Step 1: Autolyse (Optional but Recommended)

  • Mix flour and 700g water (reserve 50g) until shaggy.

  • Rest for 1–2 hours. This boosts gluten development.

Step 2: Add Starter and Salt

  • Add 200g active starter and 20g salt.

  • Mix thoroughly. Add remaining 50g water if dough is too stiff.

Step 3: Bulk Fermentation

  • Duration: 4–6 hours at 24–26°C (75–79°F)

  • Perform 4 stretch and folds every 30–45 minutes.

Step 4: Pre-Shape

  • Lightly flour bench. Divide dough and pre-shape into rounds.

  • Rest for 20–30 minutes.


Step 5: Final Shaping

  • Shape into tight boules or bâtards.

  • Place in bannetons dusted with rice flour.

Step 6: Cold Proofing

  • Refrigerate for 12–16 hours at 4°C (39°F)

Step 7: Bake

  • Preheat oven and Dutch ovens to 250°C (482°F)

  • Score the dough and bake covered for 20 minutes

  • Uncover and bake additional 20–25 minutes until deep golden



Total Time:

24–30 hours (including fermentation)

6. Professional Tips for Perfect Sourdough

  • Starter Health Is Key: Feed regularly. Use when it's at peak rise.

  • Hydration Matters: 75% is ideal for structure and openness.

  • Don’t Rush Fermentation: Flavor comes from time, not speed.

  • Cold Proof: Enhances flavor and makes scoring easier.

  • Steam Is Essential: Traps moisture for a crisp crust.

7. Equipment You’ll Need

  • Digital scale (accuracy is critical)

  • Dough scraper

  • Proofing baskets (bannetons)

  • Dutch oven or baking steel

  • Lame or razor for scoring

8. Common Mistakes to Avoid

  • Under-fermenting: Leads to dense crumb.

  • Overproofing: Causes collapse during baking.

  • Too much flour during shaping: Inhibits sealing and rise.

  • Scoring too shallow: Limits oven spring.

9. Storage & Shelf Life

  • Store at room temp in a paper bag or wrapped in a tea towel.

  • Avoid plastic—it traps moisture and ruins crust.

  • Stays fresh for 3–4 days.

  • Freezes well: slice before freezing for convenience.

10. Frequently Asked Questions (FAQs)

Q: Can I use whole wheat flour?

Yes, up to 30% substitution is common. Adjust hydration slightly.

Q: Why is my bread so sour?

Long proofing at warm temperatures increases acidity. Try cooler or shorter fermentation.

Q: How do I get large holes in my crumb?

Use higher hydration, strong flour, gentle handling, and good fermentation.

Conclusion

Mastering sourdough bread is both an art and a science. With attention to detail and patience, you can produce loaves that rival professional bakeries—crispy, tangy, and perfectly textured. This guide arms you with the essential knowledge, tools, and techniques to bake artisan-quality sourdough at home or in a commercial kitchen.
