Create your own sourdough starter and bake your first artisan loaf. A practical, step-by-step guide from day 1 to the final crust.

Sourdough Bread for Beginners: Your First Loaf

There's something special about pulling a loaf of bread from your own oven. The crust crackles as it cools. The interior has those beautiful irregular holes. You've made something from scratch that used to be out of reach for home bakers.

Sourdough bread has a reputation for being difficult. It's not. The basic process is straightforward: create a starter, mix dough, let it rise, bake it. What takes time is learning the rhythm, understanding what's happening in your dough, and trusting the process.

This guide walks you through everything: creating your starter, maintaining it, mixing your first dough, shaping, baking, and troubleshooting common problems. You don't need expensive equipment. You don't need special skills. You just need patience.

What Is Sourdough Anyway?

Sourdough bread is leavened by wild yeast and bacteria that live in a starter culture. The starter captures wild yeast from the air and flour, and the bacteria produce acids that give sourdough its distinctive tang and help preserve the bread.

Unlike yeast bread, which relies on commercial yeast (single-culture), sourdough uses a living culture. This means:

Timing is flexible - Your bread rises when it's ready, not when a schedule says it should
Flavor develops - The fermentation creates complex flavors you can't get with commercial yeast
Digestibility - Many people find sourdough easier to digest, even those sensitive to commercial yeast
Preservation - Sourdough stays fresh longer and doesn't need preservatives

The starter is your yeast source. It needs to be fed regularly to stay healthy, and it takes time to build strength. A strong starter is the foundation of good sourdough bread.

Creating Your Starter

Your sourdough starter is a mixture of flour and water that captures wild yeast and bacteria from the air. It takes about 7-10 days to create a healthy starter from scratch.

Day 1: The Beginning

Ingredients:

50g all-purpose or bread flour
50g water (room temperature, not chlorinated)

Process:

Mix the flour and water in a clean jar until no dry flour remains
Cover loosely (a cloth with a rubber band, or a lid not screwed tight)
Let it sit at room temperature for 24 hours

The mixture will look plain. You might see a few bubbles. That's fine. You're just getting started.

Days 2-3: Waiting

What to expect: The starter might look strange. There could be liquid on top (called "hooch"). It might smell unpleasant. This is normal. The good organisms are still establishing themselves.

What to do:

Discard half of the starter (or use it in other recipes)
Add 50g flour and 50g water
Mix well
Cover and wait 24 hours

Don't worry if it doesn't look active. The microorganisms are building strength.

Days 4-5: Activity Returns

By now, you should see more consistent bubbling. The starter should rise when it's active. The smell should be pleasant, like yogurt or fermentation.

Continue the feeding routine:

Discard half
Feed 50g flour + 50g water
Mix and wait 24 hours

If the starter is still not reliably active by day 5, continue feeding for a few more days. Some starters take longer, especially in cooler environments or with certain flours.

Days 6-10: Ready to Use

Your starter is ready when:

It doubles in size within 4-8 hours after feeding
It has a pleasant, slightly tangy smell
It has lots of bubbles throughout
A spoonful floats in water (the "float test")

If it's not quite ready, keep feeding and testing. It's better to wait than to start baking with a weak starter.

Feeding Ratios Explained

The feeding ratio is how much flour and water you add relative to how much starter you keep.

1:1:1 ratio (equal parts) - If you have 50g starter, add 50g flour and 50g water. This is a simple ratio that works well for maintenance.

Why not just add more? Some guides suggest adding larger amounts to avoid constant discarding. But smaller amounts are easier to manage, require less flour, and let you see the starter's activity more clearly.

The key is consistency. Feed your starter regularly, and it will thrive.

Maintaining Your Starter

Once your starter is active, you need to feed it regularly to keep it alive. How often depends on how you store it and how often you bake.

Room Temperature vs. Refrigerator

Room temperature - If you bake sourdough daily or every other day, keep your starter at room temperature and feed it once or twice daily.

Refrigerator - If you bake less frequently (weekly or less), store your starter in the refrigerator and feed it once a week.

What happens in the fridge - The starter slows down but doesn't die. It will need to be fed and brought back to room temperature before using.

The Daily Feeding Routine

Remove half your starter (or keep just what you need)
Add flour and water
Mix until smooth
Let it rest until active (4-8 hours at room temperature)
Repeat or refrigerate

Long-Term Storage

If you won't use your starter for more than a week:

Feed it normally
Let it rise once
Store it in the refrigerator
Feed once a week if you remember, or when you take it out to bake
Bring it to room temperature and feed 2-3 times before using

A healthy starter can last months or years with proper care. Some bakers keep starters that are generations old, passed down through families.

Mixing Your First Sourdough Dough

Now that you have an active starter, it's time to mix dough. You only need a few ingredients and basic equipment.

Ingredients for One Loaf

350g strong flour (bread flour or high-protein all-purpose)
250g water (about 72% hydration - this is a good starting point)
100g active sourdough starter (fed within 4-8 hours)
10g salt (about 2% of flour weight)

Total flour: 450g Total water: 250g Starter: 100g (includes its own flour and water) Salt: 10g

Equipment You Need

Large mixing bowl
Bench scraper or sturdy spatula
Digital scale (helpful but not essential)
Banneton or proofing basket (or a bowl with a towel)
Dutch oven or heavy pot with lid (optional but recommended)
Parchment paper (optional but helpful)

A stand mixer or special tools aren't necessary. A bowl, your hands, and patience are enough.

The Mixing Process

Autolyse (30 minutes to 1 hour):

Mix flour and water until no dry flour remains
Let the mixture rest covered
This allows the flour to hydrate fully and makes mixing easier

Add starter and salt:

Add the starter to the autolyse mixture
Mix until the starter is incorporated
Add salt
Continue mixing until the dough is smooth and the salt is dissolved

How to tell when it's mixed: The dough should be smooth, uniform, and slightly tacky but not sticky. It should pull away from the sides of the bowl. If it's too sticky, add a little more flour. If it's too dry, add a little more water.

The Shaping Process

Shaping creates surface tension that helps the dough hold its shape during proofing and baking. There are several techniques, but this basic round shape works for beginners.

Shaping steps:

Turn out the dough - Gently turn the dough onto a lightly floured surface
Pre-shape (optional) - Gently fold the edges toward the center to create a loose round. Let it rest 15-20 minutes
Final shape - Flip the dough so the smooth side is up. Gently fold the edges toward the center, tucking them under as you rotate the dough. Continue until you've created tension on the surface
Flip again - Flip the shaped dough so the smooth side is down. Form a tight ball by pulling the edges toward the center and pinching them together
Check the tension - The dough should look smooth and tight. It should hold its shape without spreading

Place the shaped dough in a banneton or proofing basket, seam-side up. Dust with flour if needed.

Proofing and Timing

Proofing is the final rise before baking. Sourdough proofing is different from commercial yeast bread because it's slower and less predictable.

Two Approaches

Room temperature proofing - Let the shaped dough rise at room temperature until ready (typically 2-4 hours)

Refrigerated proofing - Place shaped dough in the refrigerator for 12-24 hours (overnight is common)

Cold fermentation benefits:

More developed flavor
Easier to handle
Better oven spring
Convenient timing (bake when you're ready)

How to Tell When It's Ready

The dough should look puffy and expanded. When you gently poke it with a finger, it should slowly spring back but leave a small indentation. If it springs back completely, it needs more time. If it doesn't spring back at all, it's over-proofed.

A good rule: when in doubt, wait longer. Sourdough proofing is forgiving.

Baking Your Loaf

The baking process transforms the proofed dough into bread. The key is heat and steam for good oven spring and crust development.

Using a Dutch Oven

A Dutch oven traps steam, which is crucial for good bread.

Preheat - Place your Dutch oven (with lid) in the oven at 450°F for at least 30 minutes
Transfer - Carefully remove the hot Dutch oven, place parchment paper with the dough inside
Cover and bake - Put the lid back on and bake for 20 minutes
Uncover and finish - Remove the lid and bake 15-20 minutes more until the crust is dark golden brown

Without a Dutch Oven

If you don't have a Dutch oven:

Bake on a baking sheet
Create steam by placing a pan of water in the oven
Spray the dough with water before baking
Use a spray bottle to mist the oven during the first few minutes

Temperature and Timing

Oven temperature - 450°F (230°C) is a good starting point
Bake time - 35-45 minutes total (20 covered + 15-25 uncovered)
Doneness - The crust should be dark golden brown, and the loaf should sound hollow when tapped

Cooling and Storage

Cooling: Let the bread cool completely before slicing. This usually takes 1-2 hours. Cutting into hot bread causes the interior to become gummy as the steam escapes.

Storage:

Room temperature in a cloth bag or bread box: 2-3 days
Wrap and freeze: several months
Sliced bread toasts well from frozen

Don't store sourdough in plastic while warm - it will create condensation and make the crust soft.

Troubleshooting Common Problems

Dense or Gummy Interior

Causes:

Under-proofed dough
Starter not active enough
Oven temperature too low
Cutting into bread before it's cool

Solutions:

Ensure starter passes the float test before mixing
Let dough proof longer if it's not ready
Use a thermometer to verify oven temperature
Wait for bread to cool completely

Spreading or Flat Loaf

Causes:

Over-proofed dough
Not enough tension during shaping
Starter too weak

Solutions:

Check proofing more carefully
Practice shaping with better tension
Ensure starter is at peak activity

Pale or Soft Crust

Causes:

Insufficient browning time
Oven not hot enough
Too much steam

Solutions:

Bake longer or at higher temperature
Use a Dutch oven for better heat retention
Remove lid sooner to allow browning

Sour vs. Mild Flavor

Factors affecting sourness:

Longer fermentation = more sour
Higher temperature = more sour
More mature starter = more sour
Longer storage = more sour

Adjust these factors based on your preference.

Tips for Success

Start simple - Don't try advanced techniques until you've mastered the basics

Keep notes - Record your starter feeding times, room temperature, proofing times, and what worked

Be patient - Sourdough takes time. Rushing leads to problems

Trust the dough - Follow what the dough shows you, not a rigid schedule

Expect imperfect results - Your first loaf might not be perfect. That's normal. Keep trying.

The Bottom Line

Sourdough bread is accessible to anyone willing to learn. It's not magic or secret knowledge - it's a skill that comes with practice. Your first loaf might not be perfect, and that's fine. What matters is that you've made bread from scratch, using only flour, water, and time.

Once you've made a loaf, you have something that connects you to thousands of years of baking tradition. You've created something nourishing and delicious with your own hands. That's worth celebrating.

Start with your starter today. Keep it fed. When it's ready, bake your first loaf. The process is simpler than you think, and the results are worth it.
