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.

Hi for days 6 and 7 do you discard every 12 hours as well as feed it?
Yes!
Thank you!
I have sourdough starter made from milk and unbleached flour from my mother-in-law. I use it many times throughout the year for sourdough pancakes. I have it in the refrigerator until I want to use it then I take it out the night before and mix milk and flour to it, then take my starter out again usually 1 cup the next day and put in the refrigerator to use next time. I took my starter out and added 1 cup milk and 1 cup fresh milled hard white wheat, let this sit out on the counter for 1 day so far, it seem to rise, but not sure If this will work? It is still on my counter to work some more. I am very new to fresh milling my own flour, so please help. I would like to use my mother-in-law ‘s starter If I can. When I got this sourdough starter from my mother-in-law she said it was 50 years ago… that was about 20 years ago. It has been good to me using it for my sourdough pancakes, but this is all new milling my flour.I did change it completely not knowing, do you think I need to leave it on he counter longer or should it be in the refrigerator?
Milled flour can be more temperamental than unbleached all purpose. Sometimes it can require a higher hydration level because freshly milled flour tends to soak up more liquid. I would be a little leery leaving the milk/flour on the counter too long.
Hello! Where did you get the big glass jar you hold your starter in? Thank you in advance!

Hi. I’m new to this and was given about 1/2 c of starter from a friend. She told me to feed it 2 TBSP of flour and 1 TBSP of water daily which I have done. BUT your instructions indicate the same amount of flour as water. AND she never told me to discard anything. So now I’m now on day 7 and have about 1 1/2 c of starter which managed to increase in size by 1/3 overnight. Can I use this now, or should I start over fresh using your directions since I have not been discarding at all??? Help please. lol
If you were given a starter by a friend, it should already be active, and you can just keep it in maintenance mode. Here is my blog all about that: https://www.farmhouseonboone.com/how-to-care-for-sourdough-starter
To know if your starter is active enough to bake bread, try the float test! If it floats, you are good to go. Hope that helps!
I am on day 7 and have followed the directions completely (this is my second try). My starter is bubbly and doubled but is not floating in water. Should I continue to feed it or just try to bake with it?
Keep feeding it – sometimes it can take two weeks (even more!) to become active. When it is ready, it will past the float test.
Once my sourdough starter is ready to use, how much starter should I leave in my jar to feed? About 1 cup? 1/2 cup? I want to make sourdough and baked goods, but donโt want to use up too much of my starter and not have enough starter left over to feed and grow. Thanks!
This is entirely dependent on how much baking you will be doing. Typically, I tell people to leave about 1/2 cup in their jar before the next feeding. Then you can feed it however much you’ll need for all of your baking needs.
Thanks Lisa! Iโve been following the steps and tomorrow is my day 7. However, my starter is barely bubbly and not growing in size at all. Iโm assuming because itโs so cold. I just moved it to a warmer place, but am wondering if I have to keep feeding it twice a day or if I should feed it once a day or less. Anything else I should do? Thanks!
Hi there. So maybe Iโm over thinking thisโฆday 6&7 we feed it every 12 hrsโฆ.do we still discard half every 24โฆor do we just feed it every 12 hrs, no discard?
Thank you in advance
You discard each time you feed, just like on the other days, just more often. Does that make sense?
Is my Reverse Osmosis water considered filtered water? If not is it alright to use ?
Yes!
If Iโm using the white WW flour to start, can I later feed it with all purpose flour or should I stick to the same type of flour once I start?
Yep. I switch the type of flour all the time. It’s no big deal.
