What is a sourdough starter?
A sourdough starter is a living culture of wild yeast and lactic acid bacteria that is used to make bread rise. It is created by combining flour and water and allowing it to ferment.
Over time, the natural yeasts and bacteria present in the environment and on the flour begin to feed on the mixture. A portion of active sourdough starter is added to dough in order to make it rise during the baking process.
Sourdough bread has a distinct and complex flavor profile that cannot be beaten. The natural fermentation process in sourdough gives the bread a tangy, slightly sour taste.
The fermentation process in sourdough also helps to make the bread easier to digest for some people that might be sensitive to gluten. (It does not remove gluten from bread.)
How long will it take?
Creating a healthy and vibrant sourdough starter can take anywhere from 7 to 14 days depending on several factors. The temperature of your kitchen is the most important factor to consider.
Starters thrive in a warm environment, ideally around 75°F (24°C). But, you can still create a sourdough starter in a cooler environment.
NOTE: I created my starter in a kitchen that was 68°F (20°C) with no issues. It only required a little more patience as it took about 10 days before I could bake with it.
Trust me, this process is totally worth it. Once you've got it going, a healthy and vibrant sourdough starter will reward you with delicious bread for years to come!
What you’ll need
flour and water
The first step in creating a sourdough starter is to prepare the flour mixture which will be used to feed the starter.
Mix 6 cups of all-purpose flour with 3 cups of whole wheat flour and store it in a container with a tight-fighting lid.
NOTE: A sourdough starter can be created with all-purpose flour alone but the addition of whole wheat flour will give the starter a boost in the fermentation process.
Bottled water, filtered, and most tap water can be used in your starter. To remove the chlorine from tap water by evaporation, fill a bottle with tap water and let it sit uncovered for 24 hours before using.
Tools needed
To make a sourdough starter, you'll need a few essential tools. (affiliate links)
- First and foremost, you'll need a container to hold and cultivate the starter. We recommend either a pint-sized mason jar, a weck jar, or a food-grade plastic container.
- Covering the container with a lid or a breathable cloth, like a cheesecloth or a kitchen towel, allows air circulation while preventing contaminants from entering.
- It's also beneficial to have a rubber band to mark the starting point of the starter at feedings. This will allow you to see how much the starter has risen.
- A kitchen scale is invaluable for accurately measuring the weight of flour and water in precise ratios.
- A spoon or an offset spatula will come in handy for stirring and mixing the ingredients thoroughly.
- A digital thermometer can be helpful to monitor the ambient temperature of the room where you keep your starter.
Step-by-step instructions
You'll feed your starter once a day around the same time. Pick either morning or night depending on what is convenient for your schedule in order to stay consistent.
Day 1: Mix flour and water
Start by mixing 1 cup of the flour mixture with ½ cup of water. (120g flour + 120g water)
Stir the mixture thoroughly until all the flour is fully hydrated and no dry clumps remain.
Loosely cover the container with a lid or a thick breathable cloth, secured with a rubber band. (This allows airflow while keeping out contaminants.)
Place the container in a warm location.
Day 2: Stir
Wait 24 hours, then check on the mixture. Give it a stir to help incorporate a little air.
You should notice some initial bubbling or signs of activity.
Day 3-7: Discard and feed daily until active
Starting on day 3 you will discard most of the starter in the jar and feed it with flour and water.
Once a day around the same time, discard all but 2 tablespoons of the starter from the jar and feed it with ½ cup flour and ¼ cup water. (60g flour + 60g water) Mix thoroughly until well combined.
Repeat this daily, discarding and feeding, until your starter becomes active, bubbly, and doubles in size after each feeding. At this point, your sourdough starter is ready to use in recipes.
TIP: If your starter seems sluggish after the 4th day, start adding 2 tablespoons of flour along with 2 teaspoons of water into the jar, 12 hours after you fed it in order to help give it a boost.
How do I know when the sourdough starter is ready?
Knowing when your sourdough starter is ready to use in baking depends on a few factors. Here are some things to look for:
- A strong indication that your starter is ready to bake with is when it consistently rises and doubles after a few consecutive feedings.
- An active starter will produce small bubbles visible on the surface and on the sides of the container.
- It will have a pleasant, slightly tangy, and mildly fermented aroma.
- The texture and consistency should generally be airy and fluffy.
- The starter passes the "float test". See below.
How to perform a float test
Performing a float test is a simple way to check the readiness of your sourdough starter before baking.
To do this, take a small amount of your active starter and drop it into a bowl or glass of water. If the starter floats on the surface, it indicates that there is sufficient gas production from the fermentation, suggesting that it is active and ready to leaven bread.
If it sinks or only partially floats, feed it a few more days and test again.
How to maintain a sourdough starter
I recommend continuing to feed your starter daily for the first two weeks after you've gotten it established. Daily feedings will keep building up the yeast and bacteria and you'll end up with a very robust sourdough starter.
I have written an article that provides guidelines and tips on maintaining a sourdough starter, covering things such as feeding schedules, temperature control and troubleshooting.
You'll find valuable insights and practical advice to help you keep your sourdough starter healthy and vibrant for successful baking every time.
Frequently asked questions
How can I create a warm spot in my kitchen for my sourdough starter?
Creating a warm spot in your kitchen for your sourdough starter can help facilitate fermentation. Here are a few methods you can try:
- Near the oven: Place your sourdough starter near the oven while it's preheating or while you're baking. The residual heat can create a warm environment for the starter.
- Use a proofing box: If you have a proofing box or a proofing setting in your oven, you can use it to create a controlled warm environment. Set the temperature to around 75°F (24°C).
- Use a heating pad: Place a heating pad set to the lowest temperature under the container holding your sourdough starter with a towel in between the two. Make sure to monitor the temperature to prevent it from getting too hot.
- Find a warm spot in your kitchen: Identify the warmest spot in your kitchen, such as near a sunny window, or on top of the refrigerator. These areas often provide a slightly elevated temperature.
What if my kitchen is too warm?
If your kitchen is consistently too warm for your sourdough starter, you can use a few strategies to create a cooler environment for fermentation:
- Find a cooler area in your home, such as a basement or a pantry, where the temperature is more suitable for your sourdough starter.
- When feeding your sourdough starter use cool water from the fridge.
- Consider refrigerating your sourdough starter between feedings. Place it in the refrigerator after feeding, and take it out a few hours before the next feeding to allow it to come back to room temperature. This slows down the fermentation process and helps maintain the vitality of your starter.
- Consider using a proofing box or a temperature-controlled appliance designed specifically for fermentation. These tools allow you to set and maintain the desired temperature for your sourdough starter.
Why do I have to discard or remove the starter when feeding?
While discarding a portion of the starter may seem counterintuitive, it is a necessary step for maintaining a healthy and well-balanced sourdough starter.
Discarding a portion of the starter helps keep the overall quantity manageable. It would require larger amounts of flour and water for feeding, and make maintenance way more challenging.
By discarding a portion of the starter and feeding it fresh flour and water, you help keep the bacteria and yeast balanced.
It also helps maintain a milder flavor profile and prevents the starter from becoming overly sour.
TIP: Collect the discard in a separate container in your fridge when you feed your starter. Once you have enough you can use it to make sourdough pancakes or waffles.
Making a sourdough starter and baking sourdough bread is a rewarding and fulfilling process.
The hands-on process of sourdough baking can be a relaxing and enjoyable experience!

Margie Fuller says
Day 2 of making my starter. It’s gonna come out of my containers. Help. Margie
Amy Duska says
Hi Margie! Sounds like you've got a great start! Just transfer to a new larger container at the next feeding if you can.
Barb says
Hi, I started my starter today using a scale to measure. It was very thick compared to how yours appeared in the video. Should I add a bit more water?
Amy Duska says
It should be fine. It will become more watery as it sits at room temperature.
Barbara says
Hi Amy
I made the starter and have used it to make my first loaf of bread. Now my starter is in the refrigerator. Do I have to bring it to room temperature and feed it before I use it again? For instance, I wanted to make sourdough pancakes this morning, but starter is in the refrigerator. Should I have got my starter out yesterday, brought it to room temperature, fed it and then use it this morning?
Love your tutorials!
Thank you!
Barbara
Amy Duska says
Hi Barbara! If you are using the starter to make a "discard" recipe like pancakes, there is no need to feed the starter. You can use it right out of the fridge. On the other hand, if you are going to make bread or another baked good that calls for "active" starter, you would want to take the starter out of the fridge and feed it before using it. 🙂
Emily says
Hi there! Thank you so much for this very helpful guide! Quick question—do you transfer your starter to a clean jar every time you feed it?
Thank you!
Amy Duska says
Hi Emily, I do like to transfer my starter to a new jar when I feed it, but, it's not necessary. Just a personal choice because I like to keep the jar very clean. When starter dries it becomes very hard!
Silvia says
Hi I’ve used bread flour rather than all purpose flour by accident. Is it still ok or I need to start again? Thanks
Amy Duska says
No need to start over. Bread flour is fine!
Nina says
Hi Amy,
I made a starter and baked with it few times, I then stuck it in the frig. I have not been able to revive it yet, it’s been 7 days. Did I kill it? Should I give up and start over? Please advise.
Many thanks
Nina
Amy Duska says
Hi Nina, just feed it twice a day until it becomes active again.
Antonella says
Hi Amy! I have my starter and fed it once already but I have a question for the second feeding. Is it just feed it or do I have to discard everything but 2 tbsp every day of feeding? Thanks!
Amy Duska says
Discard all but 2 tablespoons from the previous day. 🙂
Melissa Kent says
Hi Amy,
I had to switch to the half whole wheat/all purpose flour method after 11 days since my starter was only rising a little bit every 24 hours.
It seems this method has worked and my starter is now doubling at 24 hours. I am feeding every 12 hours as instructed. Is there a point where I can go back to feeding it every 24 hours? And will I also have to feed it with both flours instead of just all purpose flour?
Thanks!
Melissa
Amy Duska says
Hi Melissa! Yes, once the starter has taken hold, you can switch back to every 24 hours if you are going to keep it at room temperature. If you keep it in the fridge, you won't need to feed it every day. You can gradually switch back to all-purpose flour too. I would feed 75% AP 25% whole wheat once and then the next with only all-purpose. This is so the balance of yeast stays strong while you transition back to all-purpose flour.
Emily says
Can I use 1 cup all-purpose flour instead of 1/2 all-purpose and 1/2cup whole wheat?
Amy Duska says
Hi Emily, yes you can. The whole wheat flour is there to give to give it a boost, but using only all-purpose flour will work too.
Jeni Mougin says
I need some advice! I used your recipe and after 2 weeks, it was only rising about an inch, so I chucked it. Started again, this time consulting The Clever Carrot website as well and feeding it with whole wheat flour. Our house is about 66* (MN in the winter). I have been keeping it upstairs for more warmth, and it's bubbly but only rising about an inch each 24 hours. On day 14, I started feeding it using 1:1:1 instead of 1:2:2 like you do as I read that possibly there isn't enough starter to "eat" all the flour added. I'm sort of grasping at straws. Any advice you have would be much appreciated!!
Amy Duska says
Hi Jeni. Mix 3 cups of whole wheat flour and 3 cups all-purpose flour in a container with a lid. This is what you will feed your starter with until it is ready. Everyday discard all but 2 tablespoons of starter from the previous day and feed it with 1/2 cup of the flour mixture and 1/4 cup of water. 12 hours later stir in 2 tablespoons of water and 2 teaspoons of water to help give it more food to eat until the next day. You will do this everyday until your starter is ready to bake with. Whole wheat flour will give it the boost it needs to flourish in these conditions. You should notice a difference in about 2 days. Please let me know how this works for you. I've given this advice to many people and they have had success with it. Good luck! P.S. The temperature of your house at 66°F is fine, it will just take a little longer than warmer kitchens.
Geoff says
Amy, thanks so much for this info. My starter, Dugan, is on day 9 and is still barely moving. He bubbles some and yesterday produced some clear liquid but that’s about it. The smell is very unremarkable as well. Is it time to let him go and start over or keep going? I feel like I’m making zero progress. Thanks much, love your tutorials!
Geoff
Amy Duska says
Hi Geoff, start feeding Dugan twice per day, 12 hours apart. Use a mixture of whole wheat and all-purpose flour to feed him with. Also, make sure the temperature where you store him is not too warm. I feel that around 70°F (21°C) is the safest. Do that for 2 days and let me know if you see some activity!
