What is Sourdough Starter

Very simply, sourdough starter is a fermented mixture of two ingredients, water and flour. Wild yeast found in flour flourishes when added to water and is allowed to rest in between feedings. This approach is the old fashioned way of making bread that has been done for centuries. It does require more time than active-dry or instant yeast but produces exceptional taste and textured baked goods. 

Tools Needed

In addittion to the flour and water a few tools are needed to make your own from scratch Sourdough Starter.

  • Kitchen Scale- It is highly encouraged to use a kitchen scale to weigh the flour and water in equals parts to achieve the best results. This is the scale shown in the picture above. However, my next kitchen scale will be a little larger to accommodate the large bowl needed to make sourdough bread. 
  • Chopsticks– This makes stirring the starter in a glass jar much easier. 
  • Glass Measuring Cup– Makes for easy pouring of water. 
  • Scoop or Spoon– Helps with the addittion of flour.
  • Medium Sized Glass Bowl– The first few days of a starters life is easier done in a medium size glass bowl. 
  • Plastic Wrap or Reusable Food Wraps– For the first few days of the starters life. 
  • Glass Jar (see below)

The type of glass jar needed will depend on which type of flour you use to make your starter and how rapidly your starter ferments. This is the jar seen in the photo below and it works beautifully when using white all-purpose flour. Please see section directly below (White Flour vs Wheat Flour) for more explanation.

White Flour vs Wheat Flour

The type of flour used will have a great influence on how your Stater ferments and the final product that you make with it. However, it is most important to not choose bleached flour as this will impede the fermentation.  

All-Purpose White Flour 

I adore sourdough bread that bites me back when I eat it. In other words, extra sour with a tang. However, my husband HATES that kind of bread. That is why I use all-purpose white flour for my Starter.

This type of flour yields breads that are very much like a crusty Italian loaf that he and I both go crazy for. Additionally, I use the Starter from this type of flour for making baguettes that then make incredible Homemade Breadcrumbs and croutons. The final products are never overly sour. 

Wheat or Rye Flour

Wheat and rye flour has more naturally occurring wild yeast. Because of this, the starter made from these types of flours will ferment faster and with more intensity. It is very important to keep a closer eye on Starters made from these flours and to use a glass jar that has a lid that is looser or can be left slightly open. The reason for this, a tight fitting lid could be a recipe for an exploding jar. 

In conclusion, wheat and rye flours will make much stronger sourdough products and all-purpose white flours (unbleached) will yield more mild final products. 

How To Make

To make Sourdough Starter that is ready to bake with will take approximately 7 days, give or take a day or two. Here are the instructions for each day.

Day 1

In a  medium sized glass bowl mix together 50 grams of water and 50 grams of flour. Stir well and cover. Let sit at room temperature. 

Pro Tip#1– To accurately weigh the flour and water start by making sure the scale is weighing in grams vs ounces. Place the bowl on the scale and turn on. The scale should read zero with the the bowl on top. Add enough flour to equal 50 grams. Calibrate the scale back to zero again and repeat with water.

Pro Tip#2– In the making and feeding of this starter there will always be equal parts of flour and water added to it. 

Day 2

To yesterday’s mixture add 50 grams of flour and 50 grams of water. Stir well and cover. Let sit at room temperature. 

Day 3

Throw away half of the Starter. To the remaining Starter add 100 grams of flour and 100 grams of water. Stir well and cover. Let sit at room temperature.

Pro Tip#3– The discarded Starter from day 3- day 6 is not fully developed enough to have any uses. Simply throw it away. 

Day 4

Throw away half of the starter. Add 150 grams of flour and 150 grams of water to the bowl and stir well. Cover and let sit at room temperature. 

Pro Tip#4– Day 4 is the day that you will notice the mixture starting to take on the personality of a Sourdough Starter. There should be small bubbles and a slight sour smell will start to take shape. 

Day 5

Similar to the previous days, throw away half of the Starter and add 150 grams of flour and 150 grams of water. Stir well, cover and let sit at room temperature. 

Pro Tip#5– The Starter should begin to look very similar to picture A below. If not do not worry, it will very soon.  Also, feel free to transfer to the glass jar once the new flour and water its mixed in on day 5. 

Day 6

Throw away half of the starter and add 200 grams of flour and 200 grams of water. Stir well, cover and let sit at room temperature. 

Pro Tip#6– By day 6 the Starter should look similar to photo A below and very possibly look like photo B. 

Day 7

On day 7 the Starter should at the least look like photo B if not like photo C. If it has a similar appearance to photo C, it is ready to use. If it looks like photo B, let it sit at room temperature for one additional day.  

Feeding and Reviving Sourdough Starter

Above all, if your Starter looks like photo C it is ready to be used for making all kinds of sourdough products. If it looks like photo B, you can still use it for baking. However, it will slow down the rising of bread dough. When it looks like photo A, it is time to feed the Starter. 

The different Stages of Sourdough Starter as it ferments.

To feed the Sourdough Starter, discard half of it and add 150 grams of flour and 150 grams of water to the remaining Starter. Stir well and let sit at room temperature overnight. If on the second day the Starter has the appearance of photo B, let it sit at room temperature for one additional day before using it in recipes. 

Pro Tip#7– If storing the Starter at room temperature it will need to be fed every 2-3 days. If storing in the refrigerator, it can be kept safely for up to 10 days before feeding. Please note that if storing in the refrigerator 2 feedings will most likely be needed before the Starter will look like photo C. 

Starter Smell and How to Know if it has Gone Bad

A healthy Sourdough Starter is going to smell sour. Therefore, it is not the best way to judge whether it has gone bad. However, the best way to know is by its appearance. If there are any visible signs of mold or red/orange spots it is time to throw the Starter out and begin again. Take heart though, Sourdough Starters are full of good bacteria. Because of this, chances of it going bad are much lower.

  1. Hi, I am a newbie to sourdough and saw your recipe and thought I would try it. I didn’t realize that I shouldn’t have used a tight lid through the process. I am now on day 7 and its watery consistency. Can I use what I have and loosely cover for a few days? Or for good results will I need to start over? It does smell a little sour. Thanks for the help!

    1. Hi Brandy! Welcome to the sourdough journey. No worries about the tight lid, itโ€™s a common hiccup for people in the beginning. The watery consistency youโ€™re seeing is hooch, which is just a natural byproduct of fermentation and a sign your starter is hungry. You can definitely try saving it!

      Hereโ€™s what Iโ€™d recommend:

      1) Stir the hooch back into the starter.
      2) Feed it 150 grams of both flour and water.
      3) Loosely cover it with plastic wrap or paper towels and a rubber band. This will allow it to breathe while keeping dust out.
      4) Discard half the following day and feed again. Repeat this process until your starter is full of life. Youโ€™re looking for bubbles and a thicker consistency. If it starts looking active and bubbly again, youโ€™re good to go!

      If it doesnโ€™t perk up, starting over might give you more reliable results, but I have a good feeling about this one. I hope this helps, and donโ€™t hesitate to reach out if you have more questions!

  2. hi, hoping for some help ๐Ÿ™‚ I’m on day 7 but if I’m honest my starter looks closer to picture A with a slight appearance of picture b? do I have to start over? do I just keep feeding everyday until it does look like picture b and c??? and if so how much 150g?

    thank you for any help you can give!

    1. Hi Krystin! No need to start overโ€”what youโ€™re describing sounds totally normal. Sometimes starters take a little extra time to fully develop that bubbly, airy texture like in picture C, but youโ€™re on the right track!
      Once you hit day 7 go ahead and discard half and feed it 150 grams of both water and flour. Watch for signs of progress, like more bubbles or a slightly tangy smell. If it seems sluggish, you can try placing it in a slightly warmer spot (around 75โ€“80ยฐF is ideal). Also, if youโ€™ve been using the same type of flour, switching to whole wheat or rye for one or two feedings can give it a boost!
      I’m guessing it will take 2-3 additional days. I hope this helps but please let me know if you have any questions. Oh, one last thing. You may find this post about maintaining your starter helpful. https://www.thefedupfoodie.com/how-to-maintain-sourdough-starter/

    1. Hi Vicki,
      Itโ€™s not uncommon for a sourdough starter to go through a funky phase, especially around day 2 or 3. That “rank” smell is likely the byproduct of wild yeast and bacteria settling in. Letโ€™s dig a little deeper into what youโ€™re experiencing:

      1) Alcoholic smell โ€“ A sharp, almost nail-polish-remover scent caused by fermentation.
      2) Sour or tangy odor โ€“ A natural part of developing lactic acid bacteria.
      3) Rotten or putrid โ€“ This could signal an issue, like contamination or improper feeding.
      If itโ€™s closer to option 1 or 2, your starter is likely on track! If it smells more like option 3, Iโ€™d recommend starting fresh to ensure the best results. Let me know if you need more help! ๐Ÿ˜Š

  3. I am about to start my very first sour dough starter and after reading the comments I guess I’m not to use the container that is pictured! But, I am unsure if I’m to cover it with siran wrap or something else. Can you advise me? oh and thank you for the trouble shooting other people’s starters, it’s a big help to watch out for.

    1. How exciting to start your first sourdough adventure! You’re right, the container doesnโ€™t have to match the picture. Any clean container works as long as itโ€™s roomy enough for your starter to grow. You can cover it loosely with plastic wrap, a clean kitchen towel, or even a paper towel secured with a rubber band (those from a broccoli bunch work perfectly!). Iโ€™m so glad the troubleshooting tips have been helpful. Wishing you lots of bubbly success!

  4. I can’t wait to get started! If I start with wheat or rye flour to get the “more sour” sour dough, when making bread, would I use white flour as normal, or do I need to use wheat or rye? Thank you!!

    1. Hi Sharnee! I am so excited for you! You are going to love making homemade sourdough! Starting with wheat or rye flour is a great choice for a tangier sourdough flavor. Just keep in mind that these flours absorb more water, so you might need to add a touch more water to keep your starter at the right consistencyโ€”thick but stirrable. When making bread, you can use white flour as normal, or stick with wheat, rye, or even a combination. And if you want, you can switch your starter over to all-purpose or a mix later on. Have fun experimenting!

  5. Hi there, this is my very first time starting my sour dough journey and I am just in my second day but I am already noticing that my starter is already starting to bubble up is this normal?

    1. Hi Yanna. Thatโ€™s wonderful to hear! Yes, bubbling on day two is completely normal and a great sign that the natural yeast and bacteria are becoming active. Itโ€™s common for this early activity to slow down over the next few days as the microbes find their balance. Donโ€™t worry if it seems less bubbly for a bit, just stick to the feeding schedule and it will pick back up as it strengthens!

  6. Hi there I just started my starter yesterday and I fed it(as instructed for day2) today and checked on it after a few hours maybe 5-6 hours after I fed it and itโ€™s already doubled its size and looking more like picture B. Is this normal?

    1. Hi Tyler. Thatโ€™s great progress! It sounds like your starter might be experiencing a “false rise”, which is normal in the early days as the yeast and bacteria are still developing. After a false rise, it may deflate or settle down as the initial gases dissipate. This is all part of the process. Just stick to the feeding schedule, and youโ€™ll see it stabilize and grow stronger over the next few days. Also, don’t hesitate to reach out with nay questions along the way.

  7. Hello. I am on day 8, and my starter still doesnโ€™t have a sour smell. It just smells like flour. Did I do something wrong??

    1. Hi Charity! Thanks for reaching out. Itโ€™s completely normal for the starter to still smell mild at this stage. It can take some time for the tangy, sour aroma to fully develop. To better help, could you let me know if your starter is bubbly and rising after feedings? These are key signs that itโ€™s active and on the right track. Let me know, and weโ€™ll figure this out together

    2. Hi Heather, thanks for the response. Yes, it is bubbly and rising. Just didnโ€™t smell sour at all.

    3. Oh good! You should be good to go for using it in recipes. As your starter matures, you will start to notice more and more of the tangy smell and flavor forming. I would love to hear how it goes so please keep me updated. Happy baking!

    1. Hi Sue! Great question! Bread flour can work well for a sourdough starter because its higher protein content may promote strong fermentation. I use all-purpose flour because it’s versatile and works beautifully. Rye and whole wheat flour are also fantastic options, especially in the early stages, as they ferment more actively. Just remember that wheat and rye flours absorb more water, so you might need to adjust by adding a bit more water for the right consistency. Bottom line, you have plenty of great options to get wonderful results. Happy starting!

  8. Hi! I just started my sourdough and I am on day three but I accidentally fed 100grams of flour and water instead of 50. Do I just continue as directed even though I have too much on day two? Let me know thank you this has been such a fun process so far!

    1. Hi Pyper! There is no problem at all. Adding a bit more flour and water is completely fine and wonโ€™t harm your starter. This might just mean the feeding process may take 1-2 more days before being ready to bake with, but all should be fine. That makes me so happy to hear youโ€™re enjoying the process. Sourdough is the best!! Happy baking and don’t hesitate to reach out if any questions pop up.
