Sourdough Academy: Complete Sourdough Guide for Beginners
Sourdough Academy
Your complete guide to learning, maintaining, troubleshooting, and baking with sourdough.
Whether you're making your very first loaf or you've been baking sourdough for years, you'll find practical guides and straightforward answers to help you become a more confident baker.
What Is Sourdough?
Sourdough is a traditional method of baking bread using a fermented mixture of flour and water called a sourdough starter.
Unlike bread made primarily with commercial yeast, sourdough relies on naturally occurring wild yeast and beneficial bacteria living within the starter.
During fermentation, these microorganisms produce carbon dioxide, acids, and other compounds that contribute to sourdough's rise, flavor, aroma, and texture.
And once you understand the basics, sourdough doesn't have to be complicated.
What Is Sourdough Starter?
A sourdough starter is a living culture made from flour and water. It contains naturally occurring wild yeast and beneficial bacteria that ferment the flour.
Think of your starter as the heart of your sourdough baking.
A healthy, active starter will generally show signs of fermentation after feeding, including:
Once your starter is active and strong, it can be used to make sourdough bread and countless other recipes.

You don't need to learn everything at once. Start with the fundamentals and build from there.
Get an Active Starter
Your sourdough starter is the foundation of your baking. Starting with an established live culture can give you a simpler way to begin.
Learn How to Feed It
Your starter needs flour and water to remain active. Understanding feeding ratios makes maintaining it much easier.
Learn When It's Ready
Learn to recognize the signs of an active starter rather than relying only on a clock.
Bake Your First Loaf
Once your starter is active, you're ready to start turning flour, water, salt, and fermentation into bread.
How Sourdough Baking Works
Although sourdough recipes can look complicated, the basic process is relatively simple.
Fresh flour and water encourage fermentation and activity.
Combine starter with flour, water, and salt.
The dough rests while fermentation develops.
Stretching and folding help build dough structure.
Once fermentation has progressed, the dough is shaped.
The shaped dough undergoes its final fermentation.
High heat transforms the fermented dough into bread.
How to Activate Sourdough Starter
A starter can become less active during storage and transportation. That doesn't necessarily mean anything is wrong.
With regular feedings and the right conditions, a healthy starter can regain its activity.
Don't judge your starter by one feeding. Consistency is more important than perfection.

Feeding provides your starter with fresh flour and water for fermentation.
Your ideal feeding routine depends on several factors, including:
There isn't one feeding schedule that works perfectly for every baker. The more you learn to observe your starter, the easier it becomes to know what it needs.
Learn how to feed sourdough starter →Sourdough Starter Feeding Ratios
You'll often see feeding ratios written like 1:1:1 or 1:2:2.
These numbers represent:
For example, with a 1:2:2 feeding, you might combine:
Understanding ratios makes it much easier to adjust your starter to fit your baking schedule.
Learn about sourdough starter feeding ratios →Sourdough Hydration Explained
Hydration describes the amount of water in your dough relative to the amount of flour.
For example:
Higher hydration doughs contain more water and can produce a more open crumb, but they can also be more challenging to handle.
Higher hydration isn't automatically better. The best dough is one you can confidently handle and bake.
Understanding Bulk Fermentation
Bulk fermentation is one of the most important stages of sourdough baking. It begins after your ingredients have been mixed and continues until the dough is ready to be divided or shaped.
Fermentation time can vary considerably depending on:
Instead of relying exclusively on the clock, learn to watch the dough.
Proofing Sourdough
After shaping, your dough goes through its final fermentation, known as proofing.
You can proof sourdough at room temperature or use a refrigerator for a cold proof.
As with bulk fermentation, there isn't one universal proofing time. Your dough, starter, flour, temperature, and recipe all matter.
Why Isn't My Sourdough Rising?
If your sourdough isn't rising properly, don't immediately assume your starter is bad.
There are many possible causes:
Learning to troubleshoot is one of the most important parts of becoming a better sourdough baker.
Live vs. Dried Sourdough Starter
If you're shopping for sourdough starter, you'll likely encounter both live and dried starter options.
A live sourdough starter is an established culture containing active microorganisms.
A dried starter has been dehydrated and needs to be rehydrated and reactivated before normal use.
Both can be useful, but they offer different experiences.

Frequently Asked Sourdough Questions
What is sourdough?
Sourdough is a traditional method of making bread using a fermented culture containing naturally occurring wild yeast and beneficial bacteria.
What is sourdough starter?
Sourdough starter is a living culture of flour and water containing wild yeast and beneficial bacteria. It is used to ferment sourdough dough.
How long does sourdough starter take to activate?
Activation time varies depending on the starter, temperature, feeding routine, flour, and other conditions. A healthy starter should show increasing activity after feeding.
How do I know when my starter is ready?
Look for signs of active fermentation such as bubbles, expansion, and a predictable rise after feeding. The exact timing varies.
How often should I feed sourdough starter?
Your feeding schedule depends on how frequently you bake, how you store your starter, room temperature, and your feeding ratio.
Can I refrigerate sourdough starter?
Yes. Many bakers refrigerate their starter when they aren't baking frequently. The starter generally needs feeding and activation before regular baking.
Why isn't my sourdough starter rising?
Possible causes include insufficient feeding, temperature, starter strength, flour, timing, or feeding ratios. Troubleshooting the specific situation can help identify the cause.
Is sourdough difficult?
Sourdough has a learning curve, but it doesn't have to be complicated. Once you understand starter activity, fermentation, and dough development, the process becomes much easier.
Can beginners make sourdough bread?
Absolutely. Beginners can make excellent sourdough bread by starting with a straightforward recipe and learning the fundamentals one step at a time.
