Learn how to make a sourdough starter recipe from scratch with just flour and water. This versatile ingredient can be used to make breads, cakes, cookies, and so much more.
If you hang around the traditional foods community, chances are you have heard of making homemade sourdough starter from scratch.
I have had my homemade starter for over six years now. It is vital in my traditional food kitchen.
What Is A Sourdough Starter?
A sourdough starter is a live active culture made of fermented flour and water that is full of beneficial bacteria and yeasts.
It is used as a way to ferment recipes and naturally rise bread.
Why You Will Love Sourdough:
If you are unfamiliar, let me fill you in on all the reasons why crazy folks, like me, go through the effort of handcrafting, and maintaining, a beneficial colony of yeasts and bacteria in their kitchens.
Before yeast was isolated and sold in little packets, sourdough starter was a valuable commodity in homes and families, passed down for generations.
Health Benefits
Have you ever heard of phytic acid? Basically, it’s an antinutrient found in grains, beans, and nuts that interferes with the absorption of certain nutrients. They are present on grains to keep them from spoiling.
There is a reason they are there, but there is also good evidence that our bodies weren’t meant to handle them. Proper preparation of grains eliminates most, if not all, of the phytic acid in offending foods.
This is the very reason traditional cultures soaked and fermented their grains, seeds, and beans. These days, we’ve lost that art. And what have we found? People can’t handle grains anymore.
Instead of using instant yeast packets, people in traditional cultures leavened their bread with a fermented starter that captured all the yeasts in the environment.
AKA Sourdough starter
How on earth do we capture native yeasts? Read on, because I explain how to make your very own starter.
Because I love good food
I already confessed my foodie tendencies with you all. I reckon it’s the same inclination that led me into the world of homemade sourdough.
Locally made sourdough starter, with the native yeasts of the area present, is certainly the thing a foodie’s dreams are made of. A jar of healthy, productive starter is teaming with life, as evidenced by all the bubbles you will see rising to the surface.
Once you’ve experienced homemade sourdough baked goods, store-bought breads and pancakes simply don’t cut it. Sourdough has a depth of flavor that just can’t be found in something made quickly with a packet of instant yeast.

FAQ:
How long does it take to make sourdough starter?
It takes about a week to create an active sourdough starter, but sometimes it can take about two weeks to make a starter ready to bake bread.
Do you have to discard sourdough starter every time you feed it?
When you are first creating your sourdough starter, yes. If you donโt discard you will have so much starter that it will be hard to keep healthy. This is because the more starter you have the more flour and water you will need to add for the yeasts and bacteria to feed on.
After having a starter for a while rather than discarding you can just use it in discard recipes. This is a much more useful way of removing some of the starter rather than throwing it in the trash.
How do you know your sourdough starter is ready to use?
You will know your sourdough starter is read to use when you feed it and after 4-12 hours it doubles in size and is super bubbly. A good way to be able to determine this, is to place a rubber band where the top of the starter is after you feed it. Then after a few hours have passed you can see just how high it has grown.
Another way is to perform the float test. Take a small glass of room temperature water. Add a quarter sized dollop of active starter. If it floats, it is ready to bake with. If it doesnโt it is not active enough.
Sourdough Starter Recipe:
By now, you know why you want to have a bowl of sourdough starter bubbling away in your kitchen, but how the heck do you make one?
Ingredients
Flour (Whole grain wheat, unbleached all-purpose, and einkorn are all great choices.)
Filtered water (I use a Berkey water filter. We have the Royal size for our family of 7. You can find my full Berkey review HERE.)
Tools
Glass bowl (Metal can react with beneficial bacteria and yeasts.)
Tea towel
How To Make Sourdough Starter
Day 1:
On day one, mix one cup of flour and one cup filtered water. Stir vigorously, making sure to scrape down the sides and incorporate everything. Place a clean tea towel over the bowl and set aside. Allow it to sit for 24 hours.
Day 2:
On day two, discard half of the mixture and repeat the process. Add one cup flour, one cup water, stir vigorously, and cover.
Why do you have to remove half the mixture? By day four, you would have sourdough starter overflowing from your bowl. Also, removing half ensures that the right amount of flour and water is feeding the growing colony of beneficial yeast. If you weren’t discarding half, the cup of flour wouldn’t be enough to feed them on days three and four. Basically, you would end up with a lot of extra starter by the end of the process, and none of it would be mature.
Day 3-5
Repeat the day two instructions for days three, four, and five.
Day 6-7
On days six and seven, do the same but feed it every 12 hours, instead of every 24.
By day seven, there should be enough beneficial bacteria and yeast present to bake sourdough bread and other fermented sourdough goodies, like pancakes and english muffins.
You will know it’s working if it bubbles, and doubles in size.
Sourdough Starter Maintenance
Once your sourdough starter is alive and active, there will be some maintenance to keep it going for years and years.
In the refrigerator for occasional use
Storing it in the refrigerator slows down the fermentation process, so one feeding per week, or every other week, is sufficient.
I usually use my starter a couple times per week. If I plan to make pancakes Saturday morning, for example, I will pull my starter out of the fridge Friday morning and add flour and water. By Saturday morning it is bubbly and ready to go.
I remove the two cups of starter needed for my pancake recipe, and put the “master starter” back in the fridge. Since it was fed the day before, it is good to go for another week, or whenever I need it next.
On the counter for daily use
Since the “little guys”, as my kids like to call the bacteria in the starter, are active at room temperature, they will have to be fed more often if keep it in this state.
If you leave your starter out on the counter, you will need to add flour and water every day. You will also have to be baking every day to use up all that starter.
Most people probably won’t use the starter quite so much, unless you own and operate a bakery. I would recommend storing it in the refrigerator between uses.

Wow, this is the most clear and easy to understand
I have been searching and searching always leaving me more confused on how to start
Really Appreciate you!!!!
So glad to hear! Thanks for sharing!
Hi my name is Hayley. I want to start a sourdough starter and have been researching it. Your videos are awesome!
My question isโฆ do I have to use filtered water? I know you said to use filtered because of chlorine or bleach but i have well water. Would that work?
Yep! Well water should be fine! I usually just use our well water.
I measured my 1 cup of flour and 1 cup of water in grams to make sure my proportions were correct (because this is my third time trying to do this)
I have SO much starter and I’m only on day 5. It will outgrow my quart jar big time by the time it is ready. Am I doing this right??
I am discarding 1/2 each day as well.
Are you discarding half at each feeding? If need be, you can discard slightly more.
I am on day six now so I will begin my feedings twice a day but yesterday I discarded 3/4 of a quart jar. I’m just not sure if my starter/ water/ flour ratio is correct now. I’ve just been guessing and discarding so much in order to keep it in the quart jar . Without having to start all over again, could you tell me how much starter to begin with today? And then I’ll go from there.
Iโm on day 4 of this process and this far every day Iโve come back to feed it and found separation. Some liquid sitting on top or in the middle. Is that normal?
It is pretty normal. That is called a hooch and it means your starter is hungry.
I am on day 6 of making a starter and there is mold all over the container (not in the starter, but there is no way to get the starter out without touching the mold). How do I prevent this for the next time I want to make a starter? I presume I have to throw this one out. I had it in a glass jar with a towel over the top. I am so sad, I was so ready to bake tomorrow!
Your jar must have drawn moisture somehow. It it a possibility that your starter is getting too warm? If you feel comfortable, you can scoop out a little bit of the starter and place it in a new jar and begin feeding it again.
Thanks so much I’m just learning about sour dough
Iโm on day 12ish and my starter still doesnโt grow (or pass a float test) and is very watery. Iโve just realized Iโve been using bleached flour, could this be the culprit? Any way to salvage? Or just start anew with unbleached flour next time?
Thank you for sharing all your experience and knowledge!
You should be able to start feeding it with unbleached from here on out and be okay. It can sometimes take two weeks or more to get your starter ready.
Hi Iโm on day 14 of my sourdough starter. I have been discarding half and making it into a pancake consistency, but it is still runny and a little bubbly. It has never risen. I thought my house was too cold so I put a heating pad around it but it isnโt doing anything. I noticed that I have been using bleached flour can that be the problem or what can I do to make it thrive. Thanks!
Sometimes it just takes a bit! I would suggest switching to unbleached to see if that helps. Have you tried the float test?
I am attempting my second starter, my first one looked and smelled right but every time Iโd bake with it my bread wouldnโt rise very much and it was super dense (it would even pass the float test) Iโm not sure what I did wrong. Can I salvage my original starter? Iโm wondering if my house temp is too warm or too cold, whatโs the optimal temperature when leaving it out on the counter?!
I would continue to try to salvage the original. How often are you feeding it? A warmer house works better for really activating the starter. Not too hot not too cold. Many people will place their starter in the oven with just the light on or another warm place.
I have a locking lid, mason jar, can I start my starter in that or does it need a little breathable tea towel over the top instead?
It needs a towel over top so that way it is exposed to the wild yeasts in the air.
I am so glad I found you online! I meticulously followed your direction for starter with my favorite flour from MN, Sunrise Flour Mill company. I first baked potato flakes bread and it is divine. Next I will make the true sourdough bread from the lovely starter that is in its 7th day now. I do not have time to do it tonight (8:00pm) but I will be working with it soon. It will go in my refrigerator for now.
Thank you for mapping out the details so carefully. It is very intimidating to start this process. My sincere thanks!
Good luck! Thanks for your kind words!
