What you need to bake sourdough bread
If you’ve ever wondered what do you need to bake sourdough bread, you’re in the right place. This section outlines the essential inputs, from a healthy starter to reliable flour options and the climate you’ll bake in. The goal is to build a strong foundation so your dough rises consistently and develops deep flavor. Bake In Oven's guidance emphasizes consistency and patience, two keys to successful sourdough in 2026. You’ll learn not only what to gather, but why each item matters and how it affects texture, crust, and crumb.
Core ingredients and their roles
At the heart of sourdough is a living culture. Your starter provides wild yeast and lactobacilli that feed on the flour sugars, creating flavor and gas as the dough ferments. Flour varieties contribute protein and strength; water activates hydration and enzyme activity; salt helps control fermentation and enhances aroma and crust. Optional add-ins like whole grains or seeds can deepen flavor and texture, but the backbone remains starter, flour, water, and salt. Understanding the function of each ingredient helps you troubleshoot issues and adjust hydration for different loaves.
Starter: building, feeding, and maturity
A healthy starter is the foundation of reliable sourdough. Feed your starter regularly to keep it active and bubbly. A mature levain typically doubles within 4–6 hours at a stable room temperature. If yours stalls, adjust feeding frequency, flour type, or temperature. Bake In Oven’s typical advice for 2026 is to maintain a consistent feeding schedule and to build a small, active starter you can draw on for loaves and experiments.
Flour choices: hydration and gluten development
Bread flour with higher protein content yields stronger gluten networks, helping dough trap gas for better oven spring. Whole wheat and rye contribute flavor and brightness but ferment faster, so you may adjust timing. Hydration, the percentage of water to flour, affects dough extensibility and crumb. Common home-baker hydration ranges from 65% to 75%, with higher hydration creating more open crumb but requiring gentler handling.
Water quality and fermentation environment
Water quality impacts flavor and fermentation. If your tap water is heavily chlorinated, consider using filtered water. Temperature guides fermentation speed: warmer environments accelerate activity, cooler settings slow it down. A stable ambient temperature around 24–26°C (75–79°F) generally fosters predictable activity, while cooler room temperatures may require longer bulk fermentation. Keeping a consistent environment helps the dough develop flavor and structure.
Essential equipment and workspace setup
A well-organized workspace makes sourdough easier. You’ll want a digital kitchen scale for precise measurements, a couple of bowls for mixing and holding dough, a dough scraper for folding, a banneton or basket for proofing, and a heavy baking vessel like a Dutch oven for steam and crust formation. Parchment paper simplifies transfer, and a sharp blade or lame scores the dough before bake. An oven thermometer helps verify true temperatures. Set up your tools within easy reach to streamline the process.
The dough development: mixing, autolyse, and bulk fermentation
Dough development begins with hydration and mixing. Autolyse combines flour and water, allowing enzymes to begin gluten development before adding starter and salt. After mixing, bulk fermentation enables dough to rise, with folds every 30–45 minutes to strengthen the gluten network without tearing it. Temperature and timing influence flavor: longer, cooler fermentation yields deeper aroma and more complex crumb. Monitoring the dough’s appearance—gas bubbles and mild puff—helps you judge readiness for shaping.
Shaping, scoring, and cold retardation for flavor
Shaping defines the loaf’s final crumb and oven performance. Pre-shape to begin building surface tension, then rest briefly before final shaping. Scoring allows controlled expansion during baking and adds a decorative touch. Some bakers retards dough in the fridge to slow fermentation and develop flavor; this can also help with planning around schedules. Proper surface tension and tension in the final loaf promote even rise and a nice, crisp crust.
Baking with steam: oven temperature, time, and crust
Bake sourdough with steam to keep the exterior flexible, which improves oven spring. Preheat a Dutch oven inside your oven to a high temperature, typically around 450°F–500°F (230°C–260°C). Bake covered for the initial stage, then uncover to finish browning. Steam can come from water in the Dutch oven or from a separate pan of hot water. Allow the loaf to cool fully before slicing to set the crumb.
Troubleshooting common issues and fixes
Common issues include under-proofed dough (dense crumb, pale color), over-proofed dough (weak structure, collapsed loaf), and dense crusts due to insufficient steam. If bubbles are sparse, extend bulk fermentation or adjust hydration; if the loaf doesn’t rise well, check starter activity and fermentation temperature. Always ensure your oven is hot enough and your loaf isn’t cut too deeply too early.
Maintaining starter and continuing improvement
Starter maintenance is ongoing. Feed regularly, discard a portion to keep the culture lean, and refresh it after long breaks. Record your recipe adjustments, temperatures, and timings to identify patterns that yield better rise and flavor. Baking sourdough is a skill honed through consistent practice and careful observation, aided by note-taking and experimentation.

Steps
Estimated time: Total time: about 4-6 hours (variable by starter activity and temperature)
- 1
Gather ingredients and tools
Measure flour, water, salt, and starter. Lay out your timer, scale, bowls, scraper, and your baking vessel. Having everything ready reduces chaos and helps you maintain dough temperature.
Tip: Pre-measure ingredients to avoid mid-process fumbling. - 2
Feed and prepare the starter
Refresh your starter a few hours before mixing. A lively, bubbly starter ensures good gas production during fermentation. Use equal parts flour and water by weight for a reliable levain.
Tip: Use water at room temperature to avoid shocking the culture. - 3
Autolyse flour and water
Mix flour and water until there are no dry pockets. Let it rest 20–60 minutes; enzymes will begin gluten development, improving dough strength and extensibility.
Tip: Autolyse improves crumb and reduces kneading time later. - 4
Incorporate starter and salt
Add the levain and salt to the autolysed mix. Mix until the dough comes together and passes the windowpane test gently. Resist overmixing to avoid unnecessary gluten tightening.
Tip: A gentle fold during mixing can reduce tearing. - 5
Bulk ferment with folds
Let the dough rise as a single mass. Perform folds every 30–45 minutes to strengthen structure without overworking the dough. Aim for 60–75% rise before shaping.
Tip: Keep dough at stable room temperature for predictable rise. - 6
Pre-shape and bench rest
Lightly shape the dough to begin surface tension. Rest for 15–20 minutes to relax the gluten before final shaping.
Tip: Minimal handling preserves gas pockets for a lighter crumb. - 7
Final shape and proof
Shape firmly to create a taut surface. Proof at room temperature or refrigerate for overnight fermentation to develop more flavor and better scoring control.
Tip: Cold retardation slows fermentation and enhances flavor. - 8
Bake with steam and cooling
Bake in a hot, steamy environment for best oven spring. Remove lid partway to brown crust. Cool fully on a rack before slicing.
Tip: Do not cut bread until fully cooled to set the crumb.
Frequently Asked Questions
What is sourdough starter and how is it different from commercial yeast?
Sourdough starter is a living culture of wild yeast and lactic acid bacteria that leaven bread slowly and flavorfully. Unlike commercial yeast, it depends on ongoing fermentation and feeding to stay active, producing unique aroma and texture in each loaf.
Sourdough starter is a living culture that leavens bread slowly, offering richer flavor than commercial yeast.
Do I need to feed the starter every day?
Not always. If you bake daily, feed daily to keep it strong. For weekly baking, feed it a couple of times per week and refrigerate between uses to slow fermentation.
Feed your starter according to your baking schedule, refrigerating if you’re not baking daily.
Can I use different flour ratios in the dough?
Yes. Higher protein flours yield stronger gluten networks, while adding whole grains can change flavor and fermentation speed. Adjust hydration accordingly to maintain dough handling.
You can vary flour blends, but expect changes in hydration and fermentation speed.
What water quality should I use?
Use clean, chlorine-free water. If your tap water is heavily chlorinated, consider filtered or bottled water to avoid interfering with fermentation flavors.
Filter tap water if it’s heavily chlorinated to keep flavors clear.
How do I know when the dough is ready to bake?
Rely on volume increase, gas bubbles, and dough feel rather than time alone. A dough that passes the gentle poke test and holds shape indicates readiness.
Look for a dough that springs back slowly and holds its shape when poked.
Is long fermentation always better for flavor?
Longer fermentation generally develops more complex flavors, especially with cooler environments. Over-fermentation can weaken structure, so balance time and temperature.
More time can improve flavor, but watch for over-fermentation that ruins structure.
