Sourdough bread is made entirely by using a sourdough starter aka wild yeast. A starter is a mix of flour and water that has been fermented and contains a natural colony of wild yeast that makes your dough rise. With a good, active sourdough starter, you won’t need any commercial yeast at all. Wild yeast works a little bit slower, so sourdough bread needs to be made over the course of a day, or even two days. It’s important you organize your time correctly. This slow development helps to tease out more complex, nuanced flavors in your sourdough bread — far beyond those of store bought ones.

Note: With your sourdough starter you are able to make sourdough bread, babka, waffles, pizza, bagels, …

You need
- 60 g all-purpose flour (or spelt flour or a mix of all-purpose and whole grain flour)
- 60 g lukewarm water
How to
The process takes about a week.
Day 1
Weigh the flour and water. In a glass jar, stir vigorously until combined into a smooth batter. It will look like a sticky, thick dough. Scrape down the sides and cover with a tea towel secured with a rubber band.
Place the jar at room temperature for 24 hours, until you begin to see the mixture bubbling up. It is important that you stir the sourdough starter every day in the morning and in the evening.
Day 2
Feed the starter. Add 60 g flour and 60 g lukewarm water, stir well to combine, and let sit out for 24 hours. Place a rubber band on the outside of the jar, at the top of the mixture, to track how or/if the mixture has grown. Stir in the evening and in the morning.
Day 3
At this point, you should see a few small bubbles here and there and it smells a bit sour, mildly sweet and yeasty. Which is great! The bubbles mean that wild yeast have started making themselves at home in your starter. They will increase the acidity of the mixture, which helps fend off any bad bacterias.
If you don’t see anything, it is possible that the process takes a little longer, it depends on the temperature in your kitchen. A colder environment may take longer. You can just continue with the stirring process for about 2 more days.
Day 4
The surface of your starter should look dotted with bubbles and your starter should be visibly larger in volume. Use a wooden spoon to discard half of the mixture, and throw it away. OR even better, you can fry ‘the batter’ in olive oil like a pancake or naan, with a pinch of salt and pepper. You will be surprised!!
Feed the starter with another 60 g flour and 60 g water. Stir in the morning and in the evening.
Continue this process for 2 more days. Discard half, then feed with 60 g of flour and lukewarm water. Your starter is like a baby, don’t forget to feed, stir every day and treat him with love. You can give your starter a name, I called mine Lemmy.
Day 5
Discard half of the mixture and feed your starter. If you don’t notice significant growth each time, feed the starter twice a day.
Day 6
If all is well, the wild yeast is quite active now. The starter should be completely webbed with bubbles and also be smelling quite sour.
You can now feed your starter just one more time and if everything is looking and smelling good, you can consider your starter is ripe and ready to use!
Day 7
You can now make the dough for bread. Don’t discard the starter but use the amount you need for your dough and then feed it with new flour and lukewarm water.
If you’re using the starter within the next few days, continue discarding half and feeding it daily. Your starter will remain active.
If you want to bake less often, you can also store the starter in the fridge. Remember to take it out and feed it at least once a week.
If you want to use your starter again, take it out of the fridge. First leave it until it reaches room temperature for at least 3 hours, then feed your starter. The starter is ready to use when it’s bubbly and airy.
FAQs
I prefer to keep around 200g of ripe sourdough starter on hand for baking, but you can certainly reduce the quantity of flour, water, and ripe starter to keep a smaller starter.
What is the best ratio to feed sourdough starter? ›
The most common feeding ratio is 1:1:1 (sourdough starter: flour: water). This is also known as a 100% hydration starter. For example, let's say you have 40 g of sourdough starter in a jar. To feed it, you'll add 40 g of flour + 40 g of water.
How much sourdough starter do I give to someone? ›
You can either split your starter into a new jar for your friend and feed both as normal ( about 100g of starter and 100g each of water and flour) or spilt some off and give them the discard to feed up. Generally, you don't need more than about 50g of starter to pass on to really get a new starter going.
How long does it take to start a sourdough starter from scratch? ›
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).
How to calculate how much sourdough starter to use? ›
Baker's Percentage of Sourdough Starter
- Fermented Flour to Total Flour: = (400/2)/(800+200) = 200 / 1,000 = 20%
- Fermented Flour to Non-Fermented Flour = (400/2)/800 = 200 / 800 = 25%
- Total Starter to Total Flour = 400 / (800+200) = 400 / 1,000 = 40%
- Total Starter to Non-fermented Flour = 400 / 800 = 50%
Ideally, it should be doubling within 4 to 6 hours of feeding - but it can sometimes happen within just 2 hours if it's warm. If your starter is not doubling, it's not ready and it will not have the ability to rise bread (and you'll end up with very under fermented sourdough bread).
Do you have to discard sourdough starter every time you feed it? ›
With each sourdough starter feeding, you'll be discarding some to avoid it from becoming overly acidic. Most will compost or trash this discard, but you can save it and use it in other recipes!
How thick should my sourdough starter be when I feed it? ›
When we send out our dried sourdough starter packets, the instructions say to make it like a thick pancake batter. That is the viscosity we prefer. We recommend doing this with a 100% hydration - remember, that is 50% flour and 50% water.
Can you overfeed sourdough starter? ›
Yes, you can overfeed your sourdough starter. Audrey explains: “Every time you add more flour and water, you are depleting the existing population of natural bacteria and yeast.” If you keep adding more and more, eventually you'll dilute the starter so much that you'll just have flour and water.
What are the portions for feeding sourdough starter? ›
Typical feeding ratios are 1:2:2 or 1:3:3 (old sourdough: fresh flour: water). However, even extreme ratios like 1:50:50 would still work. In that case, the freshly fed sourdough would just require more or much more time to grow and reach its peak, as judged by the maximum volume increase in the jar (at least doubled).
Starter that's kept at room temperature is more active than refrigerated starter, and thus needs to be fed more often. Room-temperature starter should be fed every 12 hours (twice a day) using the standard maintenance feeding procedure: discard all but 113g, and feed that 113g starter with 113g each water and flour.
Do you stir sourdough starter before using? ›
No you do not have to stir sourdough starter before you use it. You measure the sourdough starter by weight, not volume, so stirring it or not makes absolutely no difference. What does "fed" sourdough starter mean? Fed sourdough starter refers to a starter that has been fed flour and water (preferably by weight).
Which flour is best for sourdough starter? ›
The best flour blend for creating a new sourdough starter is 50% whole-meal flour (whole wheat or whole rye) and 50% bread flour or all-purpose flour. I recommend a 50/50 mix of whole wheat flour and bread flour.
How do you know when sourdough starter is established? ›
You can perform a float test to check if your starter is ready. Take a small spoonful of the starter and drop it into a glass of water. If it floats, it indicates that the starter is sufficiently active and ready for use.
Can you have too much sourdough starter? ›
If you have too much starter compared to the additional flour and water you're adding, your hungry starter consumes all the nutrients and then it's not as bubbly.
Can you overfeed your sourdough starter? ›
Premature discarding and overfeeding will weaken your starter and elongate the process. Don't discard and re-feed a weak starter before it shows increasing bubble activity or height from the previous feeding. If you don't see more bubbles or a faster rise each day, skip a feeding, and give it more time.
How much of your sourdough starter should you discard? ›
Room-temperature starter should be fed every 12 hours (twice a day) using the standard maintenance feeding procedure: discard all but 113g, and feed that 113g starter with 113g each water and flour.
What should a day 2 starter look like? ›
Day 2: Check for bubbles
Day 2 is probably as easy as it gets. You want to check if your starter has any bubbles on the surface, which is an indication that the fermentation has started. But even if you can't really see any bubbles, don't worry too much. Just leave it in a warmish place for another 24 hours.
