Sourdough Bread for Beginners: A Complete Getting-Started Guide
Sourdough seems complicated until you understand what is actually happening. You are cultivating wild yeast, then using it to leaven bread. Everything else — the schedules, the ratios, the scoring — is in service of that simple process. Here is how to start without getting lost in the rabbit hole.
- Sourdough is a two-phase process: build an active starter first, then bake with it. Most beginners struggle with the starter, not the bread.
- Your starter is ready when it reliably doubles within 4 to 8 hours of feeding and smells pleasantly sour, not rotten or like nail polish remover.
- A Dutch oven is the single most impactful piece of equipment. It traps steam and creates the crust you are chasing.
- First loaves will be dense. That is normal. Flavor and structure both improve as your starter matures over several weeks.
- Scoring the dough just before baking is not decoration. It controls where the loaf opens and prevents blowouts on the sides.
What You Actually Need
You do not need a stand mixer, a proofer, or a bread machine. Most sourdough bakers start with just:
- A kitchen scale (essential — volume measurements do not work reliably for bread)
- A large mixing bowl
- A bench scraper
- A banneton or lined bowl for shaping
- A Dutch oven
The Dutch oven is the one investment worth making immediately. It creates the steam environment that commercial ovens have built in, giving you the open crumb and blistered crust that makes sourdough worth the effort.
Building Your Starter
A sourdough starter is a live culture of wild yeast and bacteria. You create it by mixing equal parts flour and water, then feeding it daily until it becomes reliably active.
Day 1: Combine 50g whole wheat or rye flour with 50g room-temperature water in a clean jar. Stir, loosely cover, and leave at room temperature.
Days 2 to 5: Once or twice a day, discard all but 50g of the starter, then feed with 50g flour and 50g water. The discard can go into pancakes, crackers, or the compost.
Signs it is ready: The starter should double in size within 4 to 8 hours of feeding, bubble actively, and smell sour and slightly fruity. This typically takes 7 to 14 days. Colder kitchens take longer.
If your kitchen is below 68°F (20°C), move the jar somewhere warmer. The top of the refrigerator or inside the oven with just the light on both work well.
Your First Loaf
Once your starter is active, use this straightforward formula:
- 450g bread flour
- 325g water (72% hydration — forgiving for beginners)
- 9g salt
- 90g active starter (20% of flour weight)
Mix: Combine flour and most of the water. Rest 30 minutes (this is called autolyse). Add starter and salt with the remaining water. Mix until incorporated.
Bulk fermentation: 4 to 5 hours at room temperature. During the first 2 hours, perform 4 sets of stretch-and-folds every 30 minutes. The dough should feel noticeably stronger and slightly domed by the end.
Shape and proof: Shape gently, place seam-side up in a floured banneton, cover, and refrigerate overnight (8 to 16 hours cold proof).
Bake: Preheat your Dutch oven at 500°F (260°C) for 45 minutes. Score the cold dough, place in the pot, bake covered 20 minutes, then uncovered 20 to 25 minutes until deep brown.
The Gear Worth Buying
Essential:
- Dutch oven, 5 to 6 quart: Lodge and Challenger are the two standard picks
- Kitchen scale: any accurate digital scale works
Genuinely useful:
- Banneton proofing basket: shapes your loaf and wicks moisture during cold proof
- Bread lame (scoring tool): a sharp blade on a handle; a razor blade works too, but a lame is easier to control
Skip for now: bread machines, proofing boxes, specialty flours. Work with bread flour or all-purpose until your process is consistent.
Common Problems
Dense loaf: Either your starter was not active enough, or bulk fermentation was cut short. Taste a piece of your starter before baking. It should taste sour, not flat.
Flat loaf that spreads: Usually over-fermentation. Shorten bulk time or use colder water next time.
Gummy interior: The loaf is under-baked. Pull to a darker crust color than looks right. Internal temperature should reach 205 to 210°F.
Burned bottom: Raise your Dutch oven off the bottom rack, or slide a baking sheet onto the rack below it.
The Learning Curve
Your first few loaves will probably be dense with a tight crumb. This is normal. Your starter is still maturing and you are still developing feel for the dough. Baking rewards consistency more than technique. Bake the same formula weekly and you will see clear improvement by loaf 4 or 5.
Most bakers notice a significant improvement around the 6-week mark, when the starter has fully matured and the whole process has become familiar.

Common questions
- How long does sourdough take from start to finish?
- If you count starter development, plan for about 2 weeks before your first bake. Once your starter is active, a loaf takes about 5 hours of active and passive time on day one (mix, bulk ferment, shape), then an overnight cold proof, then about 45 minutes of baking the next morning.
- Can I use all-purpose flour instead of bread flour?
- Yes. Bread flour has more protein (12 to 13%) which builds stronger gluten and gives better oven spring. All-purpose works and produces a slightly denser loaf. A 50/50 blend is a reliable middle ground.
- My starter is not rising after two weeks. What is wrong?
- The two most common causes are temperature (below 70°F slows activity significantly) and chlorinated tap water (try filtered or bottled water). Adding a small amount of rye or whole wheat flour to your feedings also helps, as these contain more wild yeast than white flour.
- How do I store my starter when I am not baking?
- Keep it in the fridge once it is active. Before baking, pull it out the night before, feed it, and let it peak at room temperature before using. If you are not baking for several weeks, discard down to a tablespoon, feed with plenty of flour, and refrigerate.
- What is the difference between cold proof and room temperature proof?
- Room temperature proofing (2 to 4 hours) is faster but gives you a shorter window before over-proofing. Cold proofing overnight slows fermentation, develops more flavor, and lets you bake on your own schedule. Cold dough also scores more cleanly.
