Discover the timeless craft of sourdough baking. From cultivating your first starter to pulling a perfectly golden loaf from the oven, we'll guide you through every step of this rewarding journey. Transform simple ingredients into extraordinary bread.
Sourdough isn't just bread — it's a living thing. The wild yeast and bacteria in your starter create complex flavors that no commercial yeast can replicate. Every loaf tells a story of time, care, and the unique environment of your kitchen.
The long fermentation process develops rich, tangy notes and subtle complexity that evolves as your starter matures. Your bread becomes more flavorful over time.
The extended fermentation breaks down gluten and starches naturally, making sourdough easier on the digestive system than commercial bread. Many people find it more tolerable.
Your starter is a living, breathing ecosystem. It's a connection to baking traditions that stretch back centuries, right in your own kitchen.
Your starter is the heart of sourdough baking. It's a blend of wild yeast and bacteria that ferments your dough. Starting one takes patience, but it's simpler than you might think.
Combine equal parts whole wheat flour and filtered water in a clean jar. Leave it loosely covered at room temperature. You're creating an environment where wild yeast can thrive.
Once a day, discard half the mixture and add fresh flour and water. You'll notice bubbles forming — that's microbial activity. The smell may be strong; this is normal and will improve.
Your starter is ready when it consistently doubles in size within 4–8 hours of feeding and smells pleasantly sour. It should show visible bubbles and pass the float test — a spoonful floats in water.
Feed your starter daily if it lives at room temperature, or keep it in the fridge and feed weekly. It's now ready to transform flour, water, and salt into extraordinary bread.
Sourdough baking is a dance between time and technique. Unlike commercial yeast breads, sourdough works on a longer timeline, rewarding patience with unmatched flavor and texture.
Mix flour and water without salt, letting them rest. This allows the flour to hydrate fully and develop strength, making the dough easier to work with later.
Combine your starter with the dough and let it rise at room temperature. Perform stretches and folds every 30 minutes for the first 2 hours to build strength.
Shape your dough and place it in the fridge. Cold fermentation develops flavor and makes scoring easier. The longer it sits, the more sour it becomes.
Bake in a preheated Dutch oven at 450°F. The steam creates an amazing crust, while the interior develops an open crumb structure with those beautiful holes.
Every baker faces setbacks. Here's how to diagnose and fix the most common sourdough problems.
Likely cause: Under-fermentation or too much hydration. Try extending bulk fermentation by 1–2 hours, or reduce water content by 5%. Your dough should be puffy and almost jiggly when fully fermented.
Likely cause: Over-fermentation or weak gluten development. Reduce bulk fermentation time and perform more stretches and folds. Ensure you're building strong surface tension when shaping.
Likely cause: Cold temperatures or weak starter. Move to a warmer spot (70–75°F is ideal). Try using more starter in your next feeding, or wait a few more days for it to mature.
Likely cause: Over-proofed dough or insufficient steam. Don't proof longer than 24 hours in the fridge. Preheat your Dutch oven well, and ensure it's covered during the first 20 minutes of baking.
The right equipment makes a real difference. These are the tools serious sourdough bakers reach for again and again — chosen for function, not flash.
Traps steam during the first phase of baking, creating the ear and shiny crust that define a great loaf. A 5-quart size handles most home recipes comfortably.
EssentialA cane or rattan banneton supports your shaped dough during cold proofing and leaves a beautiful spiral imprint on the finished loaf.
EssentialA razor-sharp curved blade on a handle lets you score confidently at the right angle for maximum oven spring. Disposable blades keep it reliable.
EssentialSourdough is baked by weight, not volume. A scale accurate to 1g is non-negotiable for consistent hydration percentages and repeatable results.
EssentialCheck your dough temperature during bulk and the internal temp of your finished loaf (208–212°F means it's fully baked). Takes the guesswork out of both.
RecommendedA stiff metal bench scraper is indispensable for dividing dough, building tension during shaping, and cleaning your work surface without wasting flour.
RecommendedThe ideal vessel for your starter — straight sides let you track the rise by height, and wide openings make feeding and stirring easy without mess.
RecommendedThe open coil design mixes wet dough and thick starters without clogging. Far more effective than a spoon and easier to clean than a stand mixer for small batches.
Nice to HaveMost starters are ready to bake with in 7–14 days, though some take up to 3 weeks. Whole wheat flour speeds things up because it contains more wild microbes. Room temperature and humidity matter — warmer environments ferment faster. Don't rush it; a mature starter bakes better bread.
Yes. Cold slows fermentation dramatically. Feed your starter once a week and keep it refrigerated between bakes. Take it out a few hours before you plan to bake, feed it, and let it get bubbly at room temperature. This is convenient for casual bakers.
68–75°F (20–24°C) is ideal. Warmer kitchens ferment faster (4–6 hour bulk), while cooler ones need longer (6–8+ hours). You can work with cooler temps — just adjust your timing. Some bakers intentionally use cooler temperatures for slower fermentation and better flavor.
Depends on your timeline. Use 20% starter for a long, slow fermentation (12–24 hours), or 25–30% for a shorter bulk ferment (4–6 hours). More starter = faster rise. Most bakers land at 20–25% as a comfortable middle ground.
A Dutch oven is ideal because it traps steam, which creates the coveted crust. You can also use a covered baking stone, a cloche, or turn an oven-safe bowl upside down over your dough. The key is steam — without it, your loaf won't have dramatic oven spring or a shiny, crispy crust.
Fuzzy, colored mold (green, pink, black) means it's contaminated — discard it. Dark liquid on top (hooch) is normal and healthy; just stir it back in or pour it off. A gray or tan film is also fine. Trust your nose: a healthy starter smells pleasantly sour, not rotten.
Unbleached bread flour is the workhorse — high protein means strong gluten and good oven spring. Whole wheat and rye add flavor complexity and feed the microbes well; many bakers blend 10–20% into a bread-flour base. Avoid bleached all-purpose for hearth loaves — the gluten is weaker.
Look for volume, not time. Your dough should grow 50–75% larger, feel airy and jiggly, and show a smooth, domed surface with visible bubbles. The poke test helps: press gently — a properly fermented dough springs back slowly, leaving a slight indent. Under-fermented springs back immediately; over-fermented doesn't spring back at all.
Not dead — just hungry. That sharp solvent smell means the yeast has consumed all its food and produced excess alcohol. Feed it twice a day for a few days with a higher flour-to-starter ratio (like 1:5:5) and it'll bounce back. A well-fed starter smells sweet and yeasty, sometimes slightly tangy.
Usually under-developed gluten or over-fermentation. Do more stretches and folds during bulk to build strength, and check the windowpane — a small piece of dough should stretch thin enough to see light through without tearing. If it's over-fermented, gluten has broken down and no amount of shaping will save it; adjust bulk time next round.
If your tap water is heavily chlorinated, it can inhibit the wild microbes in your starter. Filter it, or leave a jar of tap water uncovered overnight so the chlorine evaporates. Well water and most municipal water is fine as-is. If your starter suddenly stops rising after weeks of good behavior, water is worth checking.
Use a razor blade or lame at roughly a 45° angle, cutting about ¼ inch deep in one confident swipe. A single long slash down one side gives a classic "ear" as the dough opens during baking. Score cold dough straight from the fridge — it's firmer and holds the cut cleanly. Wet blades stick less.
