What is a Sourdough Starter?

A sourdough starter is a fermented mixture of flour, water, and wild yeast. This combination of ingredients gives bread and other baked goods unique flavors and textures. Sourdough starters are created by mixing flour and water, then allowing it to sit for several days to allow the natural yeast in the air to mix with the mixture. 

During this time, the mixture will become bubbly and sour-smelling as the natural yeast converts sugars in the flour into alcohol and carbon dioxide. The resulting starter can be used as a leavening agent in baking, imparting a complex flavor and texture to the finished product. 

Sourdough starters can also be maintained over time, with regular feeding, as they continue to evolve and develop unique flavor profiles.

Why Make Your Sourdough Starter?

Making your sourdough starter is a great way to get into baking sourdough bread from scratch. A sourdough starter is a fermented mixture of flour and water used to leaven bread dough. 

The fermenting process gives the bread a unique flavor and texture that is not achievable with store-bought yeast. It also acts as a natural preservative, making your bread last longer than it would with store-bought yeast.

Making your sourdough starter allows you to customize the flavor of your bread, and the fermentation process can create new and exciting flavors that are not achievable with store-bought yeast. 

Plus, you’ll be able to save some money by avoiding having to buy store-bought yeast each time you make a loaf of bread. With your sourdough starter, you can easily make delicious and unique pieces of bread that are sure to please any crowd.

The Ingredients

Making your sourdough starter requires just a few essential ingredients. The base of the starter is flour and water. You can use any flour, but unbleached all-purpose flour works best. You will need one cup of lukewarm water for each flour. Depending on the climate where you live, you may need to adjust the amount of water for optimal starter texture. 

You will also need a spoon and a non-metal bowl or container. It’s best to avoid metal containers because they can react with the acidity in the starter. A jar or glass container with a lid works well.

Finally, you will need a spoonful of starters from a mature culture, often referred to as “mother.” This gives your starter something to feed on and helps to kickstart the fermentation process. You can find mother starters at some health food stores, or ask a friend or fellow baker if you can borrow some of theirs. If all else fails, you can try buying sourdough starter online. 

The Process

Making a sourdough starter is a surprisingly simple process requiring only a few ingredients and patience. The first step is to mix equal parts flour and water in glass or ceramic bowls, such as one cup each of unbleached all-purpose flour and lukewarm water. Stir the mixture until it is thoroughly combined, and then cover the bowl with a damp cloth or plastic wrap. Allow the mixture to sit in a warm place for 24 hours.

After 24 hours, the mixture should have begun to bubble. This means the wild yeast in the air has started to feed on the sugars in the flour and create carbon dioxide gas, which causes bumps. Next, discard half of the mixture and add one-half cup of fresh water and one-half cup of fresh flour. Stir the mixture until it is thoroughly combined, then cover it and leave it to sit for another 24 hours.

Repeat this process for two more days. By day three, your starter should be full of bubbles and have a pleasant sour smell. At this point, you can use your starter right away in any recipe that calls for sourdough.

If you’d like to store your starter for more extended periods, feed it every two days with equal parts water and flour, then cover it and let it sit overnight before using it or storing it in the refrigerator. If stored in the fridge, take out your starter the night before you use it, so it has time to come up to room temperature before baking with it.

The Results

Once the starter is ready, it can make various delicious sourdough recipes. The sourdough will have a unique flavor and aroma that can’t be found with store-bought starters. You can be sure that you have a starter full of natural, wild yeast and bacteria that will create unique and delicious results every time.


Making a sourdough starter from scratch is an easy and rewarding experience that yields delicious results. Not only is the process fun and relatively straightforward, but it also helps to create a unique flavor profile that store-bought starters cannot replicate. With patience and practice, anyone can make their sourdough starter and enjoy homemade, naturally-leavened bread.
