How to Make Sourdough Bread Starter – Easy From Scratch
Have you ever looked at a loaf of store-bought bread and wondered, what exactly am I eating? That was me, staring at an ingredient list full of preservatives, conditioners, and additives I couldn’t pronounce. No matter how much my family ate, we never felt truly satisfied, and I started questioning whether the bread we relied on was actually nourishing us. That’s when I discovered sourdough & sourdough bread starter was the first step—real bread made the way it had been for centuries, using nothing but simple ingredients and time.

The “Overwhelming” Start of Making Sourdough Bread
At first, making a sourdough bread starter recipe from scratch felt overwhelming—keeping a wild yeast culture alive sounded complicated. But I took the plunge, mixed equal parts purpose flour and water in a clean jar, and set it on my kitchen counter with a rubber band marking the level.
Within days, it bubbled with natural yeasts, and the first time I baked with my own sourdough bread starter, the deep, tangy aroma filled my home. When I pulled that golden loaf from the oven, I knew I would never go back to store-bought bread again. Now, sourdough baking is a part of my life, and I can tell you—there’s nothing more rewarding than slicing into a loaf that you made completely from scratch. And the best part? You can do it too.
I never thought I would be the kind of person who made my own bread from scratch, let alone something as traditional as a sourdough starter recipe.
For years, I relied on store-bought bread, thinking nothing of it beyond the convenience. It was easy to grab a loaf off the shelf, toss it in the cart, and move on.
But as time went on, I started to notice something was off.
The bread we were eating didn’t keep us full for long, and my kids were constantly hungry, even after eating sandwiches. I would check the ingredients list, confused as to why something so simple needed preservatives, conditioners, and added sugars.
Also, I started experiencing digestive discomfort, bloating, and sluggishness after eating certain brands. I wasn’t sure if it was the processed ingredients or something else, but I knew I needed a change.
My First Steps into Sourdough Bread
At first, it seemed intimidating. Words like wild yeast, fermentation process, and float test made me think it was something only professional bakers could master. But the more I researched, the more I realized that sourdough was how bread was made for centuries—long before commercial yeast and mass-produced loaves from the grocery store existed.
I decided to take the plunge and make my own sourdough starter.
The first few attempts were messy. I questioned whether I was feeding it properly, whether the lots of bubbles meant it was alive, and if I had ruined it entirely. But I stuck with it, learning to read the signs, trusting the process, and slowly watching it come to life.
The first time I baked a loaf, my entire house smelled incredible. The deep, tangy aroma filled the air, and when I pulled that golden-brown crust from the oven, I felt a sense of accomplishment I had never experienced in the kitchen before.
And the taste? Unlike anything we had ever had from the store.
The crust was crisp and chewy, the inside soft and airy with just the right amount of tang. My family devoured it, and for the first time, I saw them truly satisfied after eating bread.
Why Sourdough Became a Part of My Life
More than just taste, I noticed changes in our health.
The long time fermentation of sourdough broke down gluten and phytic acid, making it easier to digest. My bloating was gone, my energy levels improved, and my kids weren’t constantly snacking between meals.
I realized that this wasn’t just about making bread. It was about reconnecting with real food, understanding where it came from, and reviving a lost tradition.
Now, sourdough baking is a part of our routine.
I keep my active sourdough starter alive like a pet, feeding it and watching it grow. I experiment with different types of flour, making everything from traditional loaves to sourdough pancakes, and enjoying the simple pleasure of baking something truly nourishing.
And the best part? Anyone can do it.
You don’t need fancy equipment, expensive ingredients, or years of experience. You just need purpose flour, filtered water, and a little patience.
If you’ve ever felt frustrated with store-bought bread, wondered what’s really in the food you eat, or simply want to experience the magic of homemade sourdough, this is your invitation.
Starting your own sourdough starter is easier than you think, and once you take that first step, you’ll never look at bread the same way again. Once your starter’s ready, don’t stop at bread—use your sourdough discard for fluffy rolls or wraps that pair beautifully with a drizzle of Homemade Sweet Chili Sauce and roasted chicken or tofu.
Why Sourdough Bread is a Healthier Choice
One of the best things about making your own sourdough starter is the incredible health benefits that come with it. Unlike store-bought bread, which often contains preservatives, added sugars, and commercial yeast, sourdough is fermented using wild yeast and natural yeasts. This fermentation process is what makes sourdough easier to digest and more nutrient-rich.
A key health benefit of sourdough is that it helps break down phytic acid, a natural compound found in grains that can block the absorption of essential minerals. When given a long time to ferment, the beneficial bacteria in sourdough break down this compound, making nutrients like iron, magnesium, and zinc more bioavailable.
Sourdough is also easier on the digestive system. Many people who struggle with digesting whole grain flour or gluten in regular bread find that sourdough is much gentler. This is because the fermentation process partially breaks down the gluten proteins, reducing their impact. If you’ve ever felt bloated or sluggish after eating bread, switching to sourdough might be a good idea.
Creating the Perfect Starter for Best Results
To get the best results, it’s essential to start with high-quality ingredients. Using a mixture of flour such as bread flour, purpose flour, or whole wheat flour will give your starter a solid foundation. Some bakers also like to incorporate rye flour, as it helps encourage lots of bubbles due to its high nutrient content.
When making a homemade sourdough starter, always store it in a clean jar and mark its growth with a rubber band. Keep it in a warm place since cold environments slow down fermentation. If your house is chilly, finding a warm spot like the top of the fridge or a proofing box can help keep your starter active.
A healthy starter is full of life—it should be bubbly and have a pleasant, tangy smell. One way to test if it’s ready for baking is by doing the float test. Take a little bit of your active sourdough starter and drop it into a cup of water. If it floats, it’s ready to use in your favorite sourdough recipes.
Baking and Maintaining Your Sourdough

The best part about keeping your own starter is that you can use it in so many ways. While most people start with a simple sourdough bread recipe, you can also make sandwich bread, sourdough pancakes, or even explore creative sourdough discard recipes to use up extra starter.
When feeding your starter, use equal parts flour and water. If you have much starter, discard some before feeding to prevent it from overflowing. Using a kitchen scale helps ensure you’re maintaining the right balance. If it’s your first time working with a hydration starter, aim for equal amounts of flour and water to keep things simple.
Water quality also plays a big role in a successful sourdough. Many bakers prefer using filtered water, bottled water, or spring water instead of tap water, which may contain chlorine that disrupts the fermentation.
Mastering the Baking Process for the Best Results
Once your starter doubles in size consistently after feedings, it’s strong enough to bake with. A well-fed active starter creates better structure in the bread dough, giving it a good rise. Speaking of rising, allowing the dough enough time for a proper dough rise will ensure you get a light, airy loaf.
Baking sourdough takes patience, but it’s worth it. A properly fermented loaf has a complex flavor and texture that’s impossible to replicate with active dry yeast or commercial yeast. Baking in a Dutch oven helps trap steam, resulting in a crispy crust and chewy interior.
For those new to sourdough, the entire process might seem overwhelming, but once you establish a feeding schedule and get into a routine, it becomes second nature. Using affiliate links, you can find trusted brands like King Arthur flour or recommended tools such as a recipe card to track your baking progress.
The Problems of a Cold Kitchen
If you’re working in a cold kitchen, fermentation may take longer, so allow extra time. Some bakers use a cold oven technique to help with the bread rise. Playing around with feeding ratios and testing different types of flour will help you refine your technique over time.
If it’s your first time baking sourdough, don’t be discouraged if things don’t go perfectly right away. Every sourdough journey has its ups and downs, but with patience, you’ll be rewarded with delicious, homemade bread. Keeping an eye on the hydration level of your dough and adjusting based on your climate will also help improve your results.
So, whether you’re baking your first loaf of bread, experimenting with different sourdough recipes, or simply looking for a good way to enjoy homemade, nutritious bread, sourdough is an amazing skill to develop.
Ingredients for Your Homemade Sourdough Bread Starter

Making a simple sourdough starter recipe requires just a few simple ingredients. Here’s what you’ll need to get started:
Step-by-Step Instructions for Making Your Own Sourdough Bread Starter
Day 1: Mixing the Starter
- In a clean jar, combine equal parts flour and water. For example, mix 50 grams of flour with 50 grams water (or ½ cup flour with ¼ cup of water).
- Stir well until you have a thick, smooth paste.
- Cover loosely with a lid or plastic wrap and let it sit at room temperature in a warm place for 24 hours.
Day 2-3: Checking for Activity
- By the next day, you may see lots of bubbles forming, a sign of natural yeasts activating.
- Stir the mixture and feed it with equal amounts of flour and water (50 grams flour, 50 grams water).
- Mark the level with a rubber band and let it sit at room temperature again.
Day 4-5: Strengthening Your Starter
- By now, the mixture should smell slightly tangy and show more carbon dioxide bubbles.
- Continue feeding daily using equal parts of flour and water.
- If your house is cold (cold kitchen conditions), place the jar in a warm spot, like near a stovetop or inside a proofing box.
Day 6-7: Testing for Readiness
- Your active sourdough starter is ready when it doubles in size after feeding and passes the float test.
- To do the float test, take a little bit of your active starter and drop it into a cup of water. If it floats, it’s ready to use!
- If not, keep feeding it for another day or two, and try again.

How to Properly Store Your Sourdough Bread Starter and Bread
Storing your homemade sourdough starter correctly is essential for keeping it healthy and active. Whether you bake frequently or only occasionally, proper storage ensures your starter remains strong and ready for baking whenever you need it.
Storing Your Sourdough Starter on the Counter
If you bake often, keeping your active sourdough starter at room temperature is the best option. Simply feed it daily with equal parts flour and water to keep the natural yeasts active. Using a clean jar with a loose lid allows carbon dioxide to escape while maintaining a stable environment for the fermentation process. Marking the level with a rubber band helps track its growth.
Refrigerating Your Starter for Longer Storage
For those who bake less frequently, refrigerating your own starter is a good idea. Place your healthy starter in a glass jar, cover it lightly, and store it in the fridge. Feeding it once a week with fresh flour and warm water will keep it alive. Before baking, take it out, feed it, and place it in a warm place to reactivate.
How Long Can You Store Sourdough Bread & How to Reheat It Properly
Sourdough bread lasts longer than store-bought bread due to the natural acidity from the fermentation process, which helps prevent mold growth. However, how long it stays fresh depends on how you store it.
How Long Does Sourdough Bread Last?
- At Room Temperature: Sourdough stays fresh for about 4 to 5 days if stored properly in a linen bag, bread box, or wrapped in plastic wrap.
- In the Fridge: Refrigeration is not a good idea as it dries out the bread quickly.
- In the Freezer: Sourdough can be frozen for up to 3 months. Slice it beforehand so you can reheat individual portions when needed.
How to Reheat Sourdough Properly
Reheating sourdough correctly restores its crispy crust and soft interior. Here are the best methods:
- Oven Method (Best for Whole Loaves): Preheat the oven to 350°F (175°C). Lightly sprinkle the bread with a little bit of warm water, wrap it in foil, and bake for 10-15 minutes until warmed through.
- Toaster or Toaster Oven: For slices, toast on a medium setting to restore crispiness.
- Skillet Method: Heat a skillet over medium heat and warm each slice for 1-2 minutes per side. This works well if you don’t want to use an oven.
- Microwave (Not Recommended): If necessary, wrap the slice in a damp paper towel and heat for 10 seconds, but this can make the bread chewy.
For the best results, always reheat sourdough using dry heat methods like the oven or toaster to maintain its texture and flavor.
Once your sourdough is bubbly and ready, try it with my Whipped Honey Butter—the combo is chef’s kiss. Or make a batch of Flaky Homemade Biscuits to serve with your fresh loaf!

FAQs About Sourdough Bread Starter & Bread Baking
1. What if my starter isn’t bubbly?
It may need more time, especially in cold temperatures. Try placing it in a warm spot and feeding it twice a day.
2. Can I use different types of flour?
Yes! Rye flour, rice flour, or whole grain flour can boost fermentation and create a more active starter.
3. How do I store my starter?
Keep it on the kitchen counter if baking often or in the fridge for long-term storage. Feed weekly if refrigerated.
4. How much starter do I use for baking?
Most recipes use about 100 grams of flour worth of starter, but always check your sourdough bread recipe.
5. What should I do with the remaining starter?
Use it in sourdough discard recipes, like sourdough pancakes, crackers, or waffles.
6. Why does my dough take a long time to rise?
Fermentation is slower than using active dry yeast. Make sure your dough stays in a warm place to help it rise.
7. How do I prevent wasting too much starter?
Use a feeding schedule that keeps the starter small. Also, using equal parts flour and water for feedings reduces excess waste.
8. Can I bake in a regular pan instead of a Dutch oven?
Yes, but using a Dutch oven traps steam, which improves the bread rise and crust texture.
9. How do I adjust for different hydration levels?
A hydration starter with more water will create softer dough, while a lower hydration level makes it easier to handle.
10. Why does my starter smell bad?
A tangy smell is normal, but a strong rotten smell means it needs feeding. Use fresh grams of flour and stick to a feeding schedule.
