Simple Sourdough Starter Guide

Before baking a beautiful loaf of sourdough bread, you make a sourdough starter! A sourdough starter is a process in which you cultivate wild yeast for 6-12 days. I know this sounds complicated and time-consuming, but I promise you, all it really takes is a few minutes of maintenance each day and a keen eye for knowing when to nurture! Because yeast is a living organism, you have to feed and nurture it for it to reach a point where it is ready for bread-making. I have gone in-depth on each step of this process below.

You may be asking yourself, why can’t I just use instant yeast? Well, while instant yeast works perfectly in making things like rolls and English muffins, a sourdough starter is integral to achieving the perfect flavor and texture of sourdough bread. The sour flavor comes from acetic acid which develops during your sourdough starter’s growing process. There is a reason this process has been done for thousands of years! It is well worth the wait for better bread. Utilizing a sourdough starter will leave you with bread that is exceptionally flavorful, leavened, and with a perfect texture that cannot be replicated with instant yeast. Let us begin!

What You Need to Feed Sourdough Starter

Only 2 of the simplest ingredients are needed here- flour and water. Making the best sourdough bread does not require any fancy ingredients. It is the time, effort, and attention to detail that will leave you with the best loaf. Using only 1 cup of each ingredient will help make this sourdough starter.

  • Warm Water: Using warm water is the most important tip in growing yeast. Cold temperatures slow down fermentation which is counterproductive to the sourdough starter process. This also means that your starter should not be kept in too cold of an environment. If you live in an area with colder temperatures, you can add hot water to your mix to accelerate growth.
  • Whole Wheat Flour: I like to use whole wheat flour because it typically has a higher yeast content naturally. This makes it easier to cultivate the wild yeast and bacteria necessary to produce bread. You can also use all-purpose or rye flour, but all-purpose may not bubble up as much as other flours. As long as you are perceptive to your starter’s development, any kind of flour will work.

How to Make Sourdough Starter

Tending to a sourdough starter requires patience and diligence, but the end result is worth the time! Promise!

  1. Day 1: In a quart sized jar, add the cup of flour. Add the cup of warm water and mix into a paste. Screw on the lid tightly and set aside on the counter for 24-48 hours.
  2. Day 2-5: After about 24 hours you should see some bubbling activity. If it has bubbled significantly, it’s time to feed it! Discard all but ½ cup of the starter and add ½ cup whole wheat flour and ½ cup water and mix. Screw the lid on and set aside again for another 24 hours. If the starter is bubbling up in less time, switch to feeding twice a day instead of once a day.
  3. Day 6: Do this for 6 days and when you reach the 6th day, instead of discarding half of the starter, remove half and set aside to use in your sourdough bread.

The Ultimate Sourdough Starter Tips

Since you are growing a colony of yeast that needs certain conditions to thrive and grow, any imbalance can ruin your mix. Use these tips to make sure you get the best result out of your sourdough starter!

  • Temperature Differences: Since cold temperatures slow the growth of wild yeast, in a cold environment it may take up to 12 days for your yeast to be ready for baking. In a warmer environment, you should be ready to make your bread after 6-7 days.
  • Maintain a Schedule: The best way to get consistent results from your Sourdough Starter is to pick a certain time of the day every day to check on/ feed it. This way, you can nurture your starter as needed. It is easy to forget about it, but doing so can cause irrepairable results.
  • When Your Starter Is Ready: If your starter begins to consistently double in height a few hours after feeding, it is ready for baking. This typically happens around day 6-7.
  • Bread Isn’t Sour Enough: If your bread doesn’t have enough of a sour flavor, there are a few tricks you can try to add to your starter’s levels of acetic acid. One is to let your yeast grow in colder temperatures. It will take longer to be ready for baking, but lower temps accelerate acetic acid production which will give your dough a more sour flavor. Also, if there is a brownish liquid forming on top of your starter, mix this in rather than scooping it off. This is fermented liquid and will add sour flavor to your mixture as well.
  • Starter Smells Like Alcohol: This is usually a sign that your starter needs to be fed. When your starter is ready to be used, it should smell yeasty and bread-like.
  • Double Starter Size: You can increase the amount of starter you begin with. Just make sure your jar is big enough to allow it to double in size and then mix equal parts starter, flour, and water.

Maintaining Your Sourdough Bread Starter

Don’t throw your starter away when you are ready to make bread! Sourdough starters can be used indefinitely if properly maintained and cared for.

  • Storage: If using your starter less frequently, you can keep it in the fridge instead of on the counter top. Having it in the fridge will slow the fermentation process so you will only have to feed it once every week or so.
  • Reactivation: Sourdough Starters are fairly resilient, so even if you forget about it, it can be reactivated even after a couple months of neglect. Simply scoop off anything that is crusted over on the top, add fresh warm water, and feed regularly.
  • Hooch: If your starter has been sitting in the fridge for a while, it may begin to accumulate a liquid called ‘hooch.’ This is usually a brownish color and is a normal part of wild yeast’s fermentation process. It is a very sour, pungent liquid, so if you prefer a more sour bread, simply mix it in. Otherwise, scoop it off and continue the feeding process as normal.

Notes

If you don’t have whole wheat flour, you can use all purpose flour. It may not get as bubbly as it would with whole wheat flour, but it will work! 
If you’re using your starter less often, you can keep it in the fridge instead of on the counter top. Having it in the fridge will slow the fermentation process so you will only have to feed it once every week or so. If you forget about it, it can be reactivated even after a couple months of neglect. The longer it sits in the fridge, the more dark liquid may form on top of it. This is called hooch and can be mixed back in or poured out before you feed it. Be sure to let the starter come to room temp before feeding and then allow it to sit on the counter for 12 hours or so until you return it to the fridge.
If you would like to increase the amount of starter you have first make sure your jar is big enough to allow it to double in size and then mix equal parts starter, flour, and water.

  1. got myself in a diabetic mess so thanks to you I will go back to home made wheat bread.. much better for me again thanks. do you have other recipes you can shrare

  2. Do you let the removed starter come to room temperature before using or can you use it as soon as you pour it off after removing from fridge?

    1. You can split it instead of discarding it. You can use the discard in a recipe, start a new jar of start, or give it to a friend so they can have their own start!

  3. Instead of throwing out starter in 1st couple of days,,, can you use this in pancakes or some other sour dough recipe?

    1. You can’t use it in recipes for the first 6 days because it hasn’t fully developed and won’t lend any sourdough flavor or help your recipes rise.

  4. Are there no reviews? Tips? I’ve never made starter before and i don’t know how to use it. Is wheat bread the only kind of bread i can make with this? The other recipes say cover loosely, this says cover tightly…what is the difference? Which is better? This doesn’t say to use qll-purpose flour like the others? I’m curious about this recipe because of some negative reviews of other recipes…I would really like to know the “thinking” of these processes. I appreciate the recipe, i do plan on trying it. I personally plan to leave a review once I’m able to make a sourdough loaf. I would like to read a response first. Thanks for the recipe and your info.

    P.S.
    Just a bit of silly history here…I remember trying to make starter eons ago in the late 80’s when I thought everything had to be bon appite’ lol…I was cooking a lot & baking a lot of bread but also drinking a lot of wine like Julia Childs & Jaques Pupan’ (probably spelled incorrectly) lol but my starter kept getting moldy and i had no idea why…so i just gave that idea up and moved on lol But older now & hopefully can follow directions better lol 😉

    1. I can’t speak to why other people do things in their recipes! This one is best to do as directed. Sourdough bread usually contains wheat but it will be easier to digest than whole wheat bread.

  5. can you please give the rest of the recipe how to bake and if anything else to add before you bake
