What is the best flour for a new sourdough starter? ›

The best flour blend for creating a new sourdough starter is 50% whole-meal flour (whole wheat or whole rye) and 50% bread flour or all-purpose flour. I recommend a 50/50 mix of whole wheat flour and bread flour.

Over the past decade-plus of baking, I've tested all manner of flour from whole grain wheat to spelt to einkorn, and while they all do work, my preferred flour to use when creating a sourdough starter is whole grain rye flour and white flour (this can be all-purpose or high-protein bread flour).

For more tang: Incorporate some rye flour and/or whole wheat flour early in the bread-making process, such as when feeding the mother culture and the preferment. Rye flour in particular will help your culture produce some acetic acid.

The choice of flour in a sourdough starter is completely up to you. Whole wheat is one of many great options, so let's discuss why we might choose whole wheat. Whole grains are made up of three main components: the bran, the endosperm, and the germ.

It strikes a perfect balance of softness and structure, making it an ideal choice for various recipes. Due to its wide availability and affordability, all-purpose flour is often my top recommendation for creating and maintaining a sourdough starter.

Rye Flour: Rye flour is another popular option for sourdough starters. Naturally rich in amylases, nutrients, and microbes, this cereal flour enables a starter to quickly convert sugars for faster, more efficient fermentation.

Reasons your Sourdough Starter Might be Sluggish

Feeding schedule: A sourdough starter needs to be fed regularly to maintain its activity. If it is not fed often enough, the yeast and bacteria will become weak and the starter will become sluggish. I recommend you feed once every 24 - 30 hours, every 24 hours is better.

Myth 2: Sourdough starter requires fancy water

The key to sourdough starter success is using water without chlorine, which can cause the starter to die. While bottled water is chlorine-free, you can also use filtered tap water for our sourdough starter recipe.

*Do not try baking with your starter right after feeding it. Allow time for it to grow and feast on the flour before using it. Starters are usually ready to bake with around 4-12 hours after a feeding depending on the amount you feed your starter. The larger the feeding, the more time it needs to ferment.

Yes you can mix the flours in your sourdough starter. This can be an economical way to add some whole grains or rye. So you might want to feed 25% rye and 75% all purpose for example. There's really no hard and fast rules for what ratio of flour you use.

What if I used the wrong flour in my sourdough starter? ›

Also, the type of flour you are using can impede the rise of your starter. All-Purpose flour, for example, will not rise as robustly as a blend of bread flour and whole wheat flour. Different mixtures or types of flour will cause your starter to rise differently. I strongly recommend at least 50% whole wheat flour.

It's an easy process of mixing flour and water, discarding, and letting the mixture rest until stable and predictable fermentation happens each day. I feed my sourdough starter twice a day because I bake often.

Feed Your Starter Less (Stir In The Hooch)

Feeding your starter less will starve the yeast and bacteria and encourage it to produce hooch. If you want to make your sourdough more sour, then you need to stir the hooch into your starter when you feed it, rather than pouring it off.

Sourdough is naturally leavened bread, which means it doesn't use commercial yeast to rise. Instead, it uses a 'starter' – a fermented flour and water mixture that contains wild yeast and good bacteria – to rise. This also produces the tangy flavour and slightly chewy texture you'll find in sourdough.
