Every week I receive hundreds of questions about how to care for sourdough starter, so I decided to add all the questions I receive and my answers into this post for a reference for those who are just starting to use sourdough.

Common Questions
Once the initial 7 or so days is up, how often does it need to be “fed” if you’re keeping it on the counter top?
How often you should feed your starter depends on how much you use it during the week. I would keep it in the fridge if you only use a few times a week. A good idea is to feed it every time you use it, and then leave it on the counter for 8 hours, and then put it into the fridge until you are ready to use it again.
How long before I intend to use it do I need to take it out of the fridge?
It depends on what you are making when you should take it out of the fridge. If you are following a sourdough recipe, usually the author will tell you exactly when to do so.
My sourdough is really thick and pasty? Is it supposed to be like that?
No, it is not. If your sourdough starter is really thick, then just add a little more water until it is the consistency of thick pancake batter.
In the “How to Make Sourdough Starter” blog post, I give you the guide line of that you want a 1:1 ratio of flour to water. However, that is just a guide line. The real ratio depends on what type of flour you are using. If you are using an all-purpose flour, then you can get away with a smaller amount of water, but if you are using a whole grain wheat flour you may need more water. The basic principle is that some flours soak up water more than other flours, so the best way to find out how much flour to water ratio you need for the type of water you are using is to just play around with it.
Why do I have to discard half of my sourdough starter? Instead of discarding half of my sourdough starter on Days 2-7, can I just use it to make another separate sourdough starter?
That question doesn’t actually make sense to me, because what you are creating is basically a symbiotic colony of yeast that you capture from your local environment. What you are trying to do is just make a master starter that then can then inoculate anything else with the yeast colonies that are in it. Therefore, you do not need to create more than one. It is basically just like having double the sourdough starter which once you have an established starter you can easily do by just adding more flour and water to the bowl of sourdough starter.
It is really hard to explain, but basically what I am saying is all that you are throwing away, when you discard half of your sourdough starter on days 2-7, is flour and water. Just think of it that way. There is really no way else to make sourdough starter, because what you have is immature starter at that point and there is not really a ton that you can do with it. Especially if you are making a sourdough starter and you cannot really tolerate grains, so what you have there is not fully fermented yet.
If you are trying to avoid grains that are unfermented, you are just going to want to discard it. You can put it in your compost or feed it to your animals.
It is not like you are throwing away perfectly good sourdough starter and to create more of another one is just the same as having one main sourdough starter. Anyway, I hope that makes sense!
How do you Store your Sourdough Starter?
When you are feeding you starter, you will leave it out on the counter where it can get a little bit of air so you might put a thin tea towel or something else that is not air tight for a few hours before putting it back in fridge.
However, when it goes in the refrigerator, you are going to want to use something airtight. I personally keep my starter in a 2.5 quart glass bowl and I cover it with a silicone lid. This is what I have always done. On occasion, I have to take the sourdough starter out and clean the bowl really well because things get really crusty up on the top of the bowl and I do not want that.
How much sourdough starter do you keep on hand?
I always like to keep a pretty good amount of starter in the bowl, because there are certain no wait sourdough recipes that you can make like my sourdough skillet and sourdough pancakes. If you have enough in your bowl that you can pull from, you can always make those recipes without having to wait as long as the starter is fed and full.
Now you always want to keep enough sourdough starter in the bowl that you can use to feed again to continue on having sourdough starter. As long as you can remove enough for your recipes while leaving about a cup of starter in your bowl, you can feed it and get it back to a full bowl of starter.
How Often Should I Feed my Sourdough Starter?
That totally depends on how often you are going to use it.
Say you are going to use you starter to make pancakes every morning, or english muffins or french toast, you can leave it out on your counter and just feed it every day.
I do not use my starter every day. I use it about once a week, so what I do is keep it in the refrigerator in a bowl with an airtight lid.
To illustrate, say that it is Friday and on Saturday I want to make pancakes, I will pull my sourdough out of the fridge on Friday and add some flour and water to the bowl, mix it up, and leave it on the counter with a tea towel cover it until Saturday morning. Once I am done making pancakes on Saturday and if I am not planning on using my sourdough starter until next week, I will feed it and leave it on the counter for 8 hours and then cover the bowl with an airtight lid and leave it in the refrigerator until next Friday.
However, let us say that I am planning on using my sourdough starter again on Sunday to make cinnamon rolls, then I will just feed the sourdough starter and leave it on the counter until Sunday.
When you leave sourdough on the counter in room temperature, the yeast will again be nice and active and it will become bubbly sourdough starter. When you put it in the refrigerator, it puts the starter on pause, so you do not have to feed it as often because the yeast will relax and they do not need a whole bunch of sustenance. You can kind of think of it like a bear hibernating in the winter.
When the sourdough starter is in the fridge it does not need to be fed as much as it does when it is on the counter. On the counter it needs to be fed daily, but in the fridge it only needs to be fed once a week. You can even switch back and forth between the refrigerator and the counter if you use it sporadically such as using the sourdough every day and leaving it on the counter and then not using it for two weeks and leaving it in the refrigerator.
How much flour and water should I feed my sourdough starter?
Sourdough starters are really resilient. I have had mine for 8 years now and I never measure the flour and water. I just add enough to make the starter the consistency of thick pancake batter. I do not worry about it and it is a very happy, healthy sourdough starter.
What does “fed” sourdough starter mean when your recipes call for it?
Basically what I mean by that is your sourdough starter has had flour and water and the opportunity to sit out and feed on that.
If you are going to feed your starter, let us say it is out of the fridge, you give it flour and water and stir it up really well, you do not want to instantly put it back in the fridge even if you are not planning to use it. You want to let the starter sit out for a few hours to feed and be active for a little bit then cover it and put it back into the refrigerator. Now at that point, you could pull it out of the fridge the next day and use it for pancakes and sourdough skillet and it has been fed.
Is it okay to put my sourdough starter away unfed?
I do not usually like to put my sourdough starter away unfed, but I am not saying I haven’t done it and still worked out just fine. Once after I made pancakes on Saturday morning, I put my sourdough starter straight into the fridge without feeding it first and didn’t feed it at all until the next Friday when I pulled it out to feed it again in preparation for Saturday morning pancakes and it was totally fine. However, ideally you want to give the starter some flour and water, let it sit out on the counter for a few hours, and then put it in the fridge.
So obviously, there are way less rules to keeping sourdough starter than you might think. As you keep your starter, you will get really familiar with it.
My starter taste really sour. How can I make it so that it does not taste as sour?
Your starter may have a little bit of a smell if it hasn’t been fed in a while and your cooking projects will taste a little more sour. So if you want to avoid the super sour sourdough taste you might just need to feed it more often and not let it sit out on the counter as long. However, if you are sort of intolerant to grains, you are at least going to want to let it sit out for 24 hours to do all the fermenting work. If you are just trying to get a little bit of the sourdough taste and a little bit of that fermentation, you can let it ferment for a lot less time and avoid a lot of that sourdough taste, but it will not have the full benefit of the fermented grains.
If I receive sourdough starter from a friend, how long should I wait to use it?
I would say just feed it once and let it bubble up before using it.
How do you make sourdough starter?
Funny you should ask! I actually have a post all about that here: How to Make for Sourdough Starter
Do you know how to make gluten free sourdough starter?
I honestly have never tried it. I know that there are instructions out there on the internet. For example, after a quick Google search, I found this simple recipe for gluten free sourdough starter HERE. If you try it, let me know how it turns out!
What is your schedule for sourdough starter?
I honestly do not even have one. Every week is different. Sometimes I only use my sourdough starter one day and leave it in the fridge for a week and then the next week I use it everyday.
Is it normal for the sourdough starter to develop a hard crust over the top of it?
Yes! Whenever you have your sourdough sitting out on the counter with something that is not air tight, like a tea towel, it is totally normal. You can either scrape of the hard sourdough starter or stir it in.
What is the black layer of liquid on top of my sourdough called and why is it there?
It is called hooch. You can either dump it out or stir it in. Most likely your sourdough starter is hungry and needs to be fed, so just give it some more flour and water and it should be fine.
After day 7, do I keep discarding half of my sourdough starter?
Nope! Once the sourdough starter is established on day 8, all you have to do it just give it flour and water. You no longer need to discard half of it.
How do I know when my sourdough starter has gone bad or molded?
Honestly that is a case by case bases. I get a lot of questions about this, but I don’t really know if your sourdough starter is molded or bad until I see it.
So, honestly I do not know. I do know that your sourdoughs starter should not have an off putting smell, but it does have a sour smell to it. You should definitely be able to see if there is mold.
How do I know my sourdough starter is working after it finished day 7?
You will know it is working if works in your recipes. For example, if you are making sourdough bread and you make the dough, put it in a nice warm spot, and if it doesn’t rise that means your starter is not full established and you need to keep on making it or you just need to throw it away and start over.
Your sourdough starter should definitely rise if it is good and active. You will also see a lot of bubbles on the top as well.
Why is sourdough starter much healthier than just regular flour?
This has to do with the grains and the fermentation. A lot of people today cannot tolerate grains. For the most part, a lot of people have given up grains and going gluten free and grain free.
I am not a doctor or a food expert, but I can tell you what I know about it.
Outside of a grain, there is a protective layer called phytic acid. That phytic acid is very incompatible with your body absorbing and digesting those grains. When you ferment those grains, the fermentation process takes care of that pre-digesting work for you and it makes the grains and the nutrients in them more easily accessible for your body to recognize it and use it without having to go through those original steps of breaking down the phytic acid which can be very taxing and difficult for your body. Plus, fermentation just makes the nutrients more readily available. What was locked up inside the phytic acid in the grain, the outside of the bran, is now available for your body to use, so a lot of the vitamins that are in the grain are not actually doing you any good and fermentation unlocks them.
A lot of the time, people who are not tolerate of grains, find that they can tolerate sourdough starter if it has a least sat out on the counter for 24 hours.
I cannot tolerate grains. Do you think that I will be able to tolerate sourdough starter?
I personally can tolerate grains just fine, but if you are a person who cannot tolerate grains, but not if you have celiac, then maybe you can tolerate sourdough starter that is fermented for at least 24 hours. However, if you have celiac then you will more than likely not be able to even tolerate sourdoughs starter, but definitely check with your doctor.

Dewena says
I watched your sourdough video this morning while eating breakfast that included a thick slice of toasted buttered sourdough bread from the Publix bakery. It was delicious until I remembered my mother’s homemade sourdough bread and listened as you talked about yours. I’ve never made the starter but my mother used to bring me hers in a tupperware bowl on the plane and I made the best bread with it. I wasn’t too good at keeping it going a long time and Mama finally told me that the current bowl she brought me would be the last. She’s been in a nursing home for nine years now many states away and I sure wish I had another chance to sample her wonderful bread. I’ve pinned your recipe and will try once again!
Lisa says
Hi Dewena,
I hope you do try it again. It really is super simple once you get started 🙂
Evan Weatherup says
Can I use actual bread flour? I started my starter 4 days ago and I have tiny bubbles on top but it seems very thick and clumpy. I’ll add water to strive for the pancake batter consistency and see if that helps.
Kim says
I am so excited to make my starter! Thankful to have found your blog/videos.
My question is if I begin my starter in a container it out grows can I transfer it to a larger container? Beside the obvious, cool with it, is it okay to transfer starter?
I will probably start in a mason jar or glass bowl but would love to move it to a glass jar similar to the one your’s is in in recent videos.
Thank you!
Renae Richard says
Can I use all-purpose einkorn flour(Jovial) in your starter recipe? Also, can I use less flour to start if I am only making 1 or 2 loaves of bread weekly? I don’t THINK I will need so much starter??
Lisa says
Yes, you can use einkorn. The amount of starter you keep on hand won’t have anything to do with how much you use to start with. Think of it as building up a beneficial colony of bacteria and yeasts. Once you have that you can add any amount of flour and water that you want. For example, right now I have three cups of starter on hand (ish) but if I want to make pancakes tomorrow I will add several cups of flour and water tonight. Sometimes I have as little as a quarter cup.
Katy says
Hi! I received sourdough starter from a friend and have been feeding it once a week keeping it in the frig. I made your English muffins and they were delicious! My question is what is the right way to build back up my amount of starter? Just leave it on the counter and feed it every day? I was understanding that if I left it out it needed to be fed every day and also used every day, is that right? I just wanted to build back up the amount..
Lisa says
You can just add as much as you need once it’s mature. I will just throw in two or three cups of flour and water and let it sit out, when I was a whole lot!
Katy says
Ok! So if I leave it out and feed it each day, I don’t need to use it every day? Does it mature the longer it’s at room temperature (& being fed each day)?
Jessica says
Once you are to the point of the sourdough being established and not having to discard half. Do you feed it roughly a ratio of 1:1:1 of starter, flour and water?
Lisa says
Yes, that’s correct!
Candace says
Hi Lisa! I am on day 3 of my starter and it smells terrible….like vomit. This is my 4th or 5th time making a starter over the years and I don’t remember it ever smelling like this. The smell began yesterday (day 2). I use unbleached all purpose flour and berkey filtered water in a glass bowl with a tea towel on top. Is this normal the first few days? The starter has been very bubbly at each feeding…..it just smells so bad! I am 30 weeks pregnant, so it’s possible my hormones are affecting my sense of smell, but even my children say it smells terrible. I know you’re about to have a baby any minute, so I’ll just keep at it and see if the smell changes in the next day or two.
Thanks,
Candace
Tara says
I had a few batches that were the same. We threw them out. I have one that looks to be working and is NOT like that! No vomit smell. No crazy bubbles at the very start. I hope that helps.
Emily says
If I wait 24 hours for my starter to fully ferment before using it to bake, will it still act as a leaven? Do I have to use it at its peak bubbly (before it deflates) if I want my bakes to rise?
Bridget says
I had a sourdough starter i made for several months, I stored it in an air tight container in the fridge, one day I pulled it out and let it sit on the counter to warm up I went to feed it and it was molded..I had just used this the week before..why would it have molded do you think?
Lisa says
Usually this means some type of contamination got in.
Kira says
Hello! Thank you for all of your instructions for creating and maintaining a sourdough starter! I have a question…. After pulling it out of the fridge to rejuvenate do you discard a portion and then feed your starter? Or do you just feed it and then sit it out on the counter to ferment?
Lisa says
Just feed it and let it sit on the counter!
Lindsay says
If you’ve been nervous to attempt a sourdough starter, like I was, don’t be. Lisa’s instructions were super easy! I have switched the flour up twice now in only 2 months time and my starter is still thriving! Definitely give it a go!
Lisa says
Love to hear that!
Susannah says
Hi! Do I stir the flour and water mix on days 2-6 before discarding half? Thanks!
Sandra says
Hello,
This is my first time working with a sourdough starter. My starter is 7 days old today and well it has out grown it’s container. My question is do I move it to another container? Do I discard some of it and continue o row it? Do I refrigerate it? Please Help!
Sandra W
Lisa says
The best option would just be to start making a whole bunch of pancakes. That will solve your problem quickly as they take up a lot of starter.
Frith says
Hello, I’m wondering if you have to use the same type of flour when making the Sourdough starter and each time you feed it or can you feed it different varieties? Thanks!
Lisa says
You can totally switch it up!
Tiffany says
I think I may have lost track of which day I was on with my starter and inadvertently started feeding every 12hrs on day five instead of day six. Today is day “seven” according to my new schedule, but if I’m right about my suspected mistake it’s actually only day six. Should I just feed for one more day to be safe, or have I ruined it?
Lisa says
It should be fine! Just continue with the twice per day feedings!
Jillanne says
Hello,
I’m in day 8 of my starter and have been trying all sorts of discard recipes along the way so I’m inundated with all the things. So, I fed it last night (last of 2 a day feedings). To be sure I follow, I take from it as it is to make say bread, and then feed it, and put it in the fridge until about 24 hours before I want to bake again. Us that right? Can I just put it in the fridge now and pull it out before I want to use it? It feels like all I’ll ever have is discard.
Lisa says
Yes, you can just put it back in the fridge until you want to use it again. You will only have discard while establishing it. After that, just keep as much on hand as you need.
Aubree says
Hi, first off I love your blog and youtube! Thanks for sharing all this amazing stuff with us. I am going to start a sourdough starter, I am going to grind my own flour for it. Which flour do you like best? Should I use whole wheat or einkorn? Is the consistency of a whole wheat starter compared to einkorn different? I just dont know which one to use, or if it matters since it is healthy either way because it is fermented.
Thanks
Aubree
Catherine says
Hello; i started my sourdough 2 days ago with wholemeal flour. yesterday the jar filled with the starter and so i had to put my starter in another glass. would this ruin the process? in my first trial last week i did it with all purpose flour and i found like a thin layer of water on top of the sourdough mixture. why does this happen? thank you
Robyn Day says
Hi, I am on day three of the sourdough starter process and I have noticed by the next morning my starter has doubled, but if I wait the full 24 hours it deflates and gets a water layer on top. Does this just mean it needs to be fed more often?
Amy Warriner says
Hi I started my starter with 50g each of water and multigrain flour. I am on day 4 and was wondering if i could up the amounts to 100g of each or will that throw off the mix. Also would i still remove half of the current starter before adding the new amounts.
vanessa says
Hi! I used my starter for some time now and just put it in fridge for the first time. my question is when I take it out it smells like vinegar like crazy and a lot fo watery stuff on top. is this normal? also, do I feed it straight out of the fridge? or what til room temperature? thanks
Darlene says
Hi, I have a quick question. I am now on day seven and while I was re-reading your blog and instructions. I realized that I completely forgot that on day six and seven you’re supposed to feed the starter every 12 hours. I was continuing to do every 24. it smells fine. it’s bubbly and it’s thick like a thick pancake batter. am I OK? I was going to just do the eight day tomorrow and feedback it twice, every 12 hours and wait till the 9th day to use it. will that work? Thanks
Lisa says
It should be totally fine! Sounds like it’s thriving!
Jen says
Hi! I’ve read your q and a and haven’t seen answers to these…
1) is it 1 cup packed (or loose) flour?
2) is water measured with a dry or liquid measuring cup?
3) does it ever get bigger than double it’s size after feeding? (I’m using a 34oz mason jar. Covered with a paper towel that is secured by the lid ring.)
4) do you have any suggestions with traveling with a starter while in the process of making it? I travel between my two homes every other week. One house is brick and mortar In the city, with hvac. One is a trailer out in the middle of nowhere… I was thinking I could keep it in the microwave there?
Thank you in advance!
Suzette says
Hello! I’m at Day 7 but my starter is not very bubbly. There are some… Definitely does not look like your healthy mix pictured. I also always have a layer of clear/yellowish fluid on top every time I go to feed it. Is there something wrong? Can I use it? Thanks for any help.
Suzette.
Lisa says
The layer on top is called hooch and just means you need to feed it with a bit more flour and water, or more often.
Suzette says
Excellent! Thanks so much.
Kirsten Hull says
Hi!
I’m only on day one of my starter and did the 1:1 ration (1 cup water, 1 cup unbleached flour). It’s hour 15 and has a fair amount of hooch on it. I fed it, but this time measured at 50g of starter, 50 g four, 50 g water because I didn’t know what “half” would be other than eyeballing it. Is the hooch normal for the first day, and should I have fed it right away? Is the way I’m measuring it correct?
Karen says
Possibly what one of your followers was asking on this question- Is when they are discarding half of the future starter could they create another starter and keep up the process and give this to others….. and in that case the answer is yes. We used the discard (though not mature) to add to waffles, pancakes or make fry bread which is similar in fashion to your pizza crust but on the stove top–
Best,
Karen
This was the question I am referencing:
Why do I have to discard half of my sourdough starter? Instead of discarding half of my sourdough starter on Days 2-7, can I just use it to make another separate sourdough starter?
That question doesn’t actually make sense to me, because what you are creating is basically a symbiotic colony of yeast that you capture from your local environment. What you are trying to do is just make a master starter that then can then inoculate anything else with the yeast colonies that are in it. Therefore, you do not need to create more than one. It is basically just like having double the sourdough starter which once you have an established starter you can easily do by just adding more flour and water to the bowl of sourdough starter.
Vicki says
Do you use the starter in it just fed bubbly form to make bread or wait until it goes down a little to use?
Meghan says
I’m new to using a banneton basket and my dough is sticking. I started using it because my dough would stick terribly to my towel/bowl rising method. I would get a GREAT rise but then it would go downhill fast when transferring to my cast iron.. any tips?
Deanna says
Hello, thank you for the tips. I’ve been making sourdough bread now for a few weeks and it’s been great. The person I received the starter from told me to remove 200 grams and add 100 grams each flour and water when feeding. She said I should have 100 grams left of the starter prior to putting in the new flour and water. I never have that amount left. So I’ve been removing 100 grams discarding the remainder and then adding the extra, but I still never have 100 grams remaining after discarding 200 grams. Why would I be losing this weight? Is this a problem?
Elizabeth says
I have had my starter a few months now. When I feed it, it rises like a champ. Beautiful and bubbly, doubles in size. Every time I try to use it in a recipe I never get even the slightest rise in my dough. Does this indicate bad starter? My house is usually 68° I keep it in the oven…
Monica says
Do I need to discard half when I feed it AFTER the 7th day?
Lisa says
No, only while you’re building it up.
Kristina says
Hi there, I just started my bread starter… after it’s done “starting” can I transfer it over to the clamped jar or do I have to keep it in a bowl? I love the idea of the clamped jar for space reasons… tia☺️
Tracy Gavigan says
Hi Kristina….I am on day 6…I will be putting mine in a clamped jar ! i need the space as well ; )) I am counting on this being OK haha
Tracy
Val Colvin says
Hello!
I’ve baked in a technical way with sourdough for YEARS… We’re downsizing our farm and I’ll no longer ferment dough in 5 gallon buckets for large batches of bread! Yay! I’d like to relax my feeding also as I’ve watched you just dump cups of flour and water into your jar. I’m stuck in the rut of taring the weight of my jar, weighing my starter, and then adding equal amounts of flour and water. Do you estimate how many cups of starter you have? Then I assume you adjust the thickness… Ready to relax my methods!
Momma to 13
Val
laura says
Hi there!
I’m on day 5 of my starter, using whole wheat flour. I noticed that yesterday and today it hadn’t grown but is instead separating. There is a layer of liquid at least an inch on the top. Is my started still ok or should I start over again?
Ella says
Hello Mrs. Lisa,
First I just wanted to say your blog has been so helpful in keeping a healthy sourdough starter, and your recipes make so excited to try them! But I have question. If I keep my sourdough starter on the counter at room temp, do I have to feed it every day even if I won’t use it to cook on that particular day?
Thank You!
Alley Bates says
Wow! I love your website! Your FB videos recently showed up in my videos section and I cannot get enough of your videos. This is my first time checking out your blog site and it certainly won’t be my last.
Thanks for your videos and blog!
Inna says
Thank you for all the info! I have 2 questions.
Do I have to feed my starter before putting back in the fridge even if I fed it like 5 hours ago to make leaven?
After feeding my starter, it only takes 2 hours for it rise before falling back down? I use it to make sourdough bread and most recipes say it takes 4-12 hours for it to rise. What can be the reason that it’s taking only 2 hours? And is it a problem that it takes only 2 hours?
Thanks!
Cathy says
When feeding a mature starter, I discard until I have 100 g starter and add equal parts flour & water; 100 g flour and 100 g water. Is it necessary to have equal parts starter to feed? Do I have to discard that much starter? Can I just feed without discarding to grow the amount? Or at what point do I need to discard starter before feeding?
Ali says
Do you need to feed the starter with the same flour as the original starter? For example whole grain wheat with whole grain wheat. Or is it’s okay to switch it up such as whole grain wheat original starter with all purp flour for feeds?!
Pam says
Do you always use the same kind of flour or flour blend when feeding your sourdough starter?
Erika says
Ok. By now I’ve watched all the videos and read this post and I haven’t seen my questions anywhere: Can I use my stainless steel measuring cups to measure out the flour and water for the sourdough? When using a recipe that calls for sourdough can I use those same stainless steel cups to measure the sourdough itself? And while I am planning to get some glass bowls before starting my sourdough, can I make a sourdough recipe in my plastic mixing bowls or does it have to be glass?
Lisa says
Yes, I use stainless all the time!
Erika says
Ok, thanks! I’m headed to the second hand store tomorrow and if I get at least one glass bowl and a new-ish looking wooden spoon I’ll finally try to make sourdough!
