How to Make A Sourdough Starter

How to make a sourdough starter in little as eight days. The most effective way to make an active starter as quickly as possible with day-by-day photos and instructions.

Have you been bit by the sourdough craze? Maybe you tried to make a starter and it just didnt work out. Maybe your nervous to give it a shot. 

That’s why I'm here! 

I started my sourdough journey in July of 2019 (pre pandemic baker!) and haven't stopped since. I have helped so man people get a starter of their own going as well as conquer that first loaf. 

And I can help you. 

It took me multiple attempts to get my starter active as well as make my first loaf so I’m here to say, it’s not always easy. But it is well worth it. 

I started in July, but didn't make my first successful loaf of bread until Christmas. So it took me almost 5 months to make that first loaf of bread. 

I have complied all my wins, and failures, and have a technique that I hope helps cut out all that time (and flour) I wasted. 

I have made multiple starters and using the method here I had one going in just 8 days. My first one took almost 4 months. 

Let’s take a look first at what a starter even is before we dive in to making one.

What is a Sourdough Starter?

The quick definition, it is a leaven for baked goods. 

What is a leaven? A leaven is what gives rise to baked goods. It can be instant yeast, baking soda, baking powder and a sourdough starter. It what takes dough or batter to a fluffy and soft treat. 

But what is it really?

Sourdough Starters are a mix of flour and water that has fermented over time, and host a live culture, that can be used to give rise to breads and other baked goods. 

It collects the wild yeast and microbiomes  in our environments, trapping it inside the flour, and bringing it to life. 

Basically we are creating a live environment inside the flour mix. 

This ecosystem is what gives beautiful rise to bread and other baked goods. It has been done for centuries and still works today. 

If you are interested in more of the actual science behind what is happening Serious Eats has a great article breaking it all down.

A sourdough starter has even been found to be easier to digest with some people. The reaction that takes place breaks thing down that our bodies have a hard time to digest. It also doesn't require any sugar to make it active.

So many commercial bread products have loads of sugar and other additives that sourdough just doesn't need. Making it better for our bodies.

Because we feed and care for a starter that means it can live a long time. How long can a starter live? There are claims that some sourdough starters have been passed down for generations, and are over 100 years old!

As long as they are cared for properly, they can last a lifetime. 

What Can You Do With a Sourdough Starter?

There are endless possibilities for that starter. 

First off is that classic loaf of sourdough bread.

Sourdough bread calls for very simple ingredients and only uses flour, water, salt and the starter. It requires zero yeast, no sugar or dairy, and a longer proofing time.

All resulting in the best and freshest tasting bread. 

In addition to bread, there is along list of things you can use that starter in. 

Thing you can make with a starter include: Pancakes, pizza, quick breads, crackers, muffins, cookies and just about anything else that needs a leaven. 

Some recipes take time to rise and others require no time. Get all my recipes that use a sourdough starter. 

Equipment and Ingredients

Equipment

Digital Scale. The best way to measure out the ingredients. Cup measurements are not as accurate. 1 cup of flour can vary between 110-140 grams of flour. That is a huge difference.

2 glass bowls, containers or jars. I like to have two bowls so the starter can be transferred to a clean one. While some prefer to use a jar, I just find a bowl so much easier to use. 

Danish Dough whisk. Not necessary but definitely makes it easier. A wooden spoon can also be used.

Flour sack towel or tea towel: you want a towel to cover the bowl. It needs to be light enough to let in the thing we want, but heavy enough to keep out the things we don't.

Ingredients

Ther eare only two ingredients needed to make a starter. 

Flour and filtered Water

The type of flour is up to you. The preferred is going to be unbleached all-purpose flour but bread flour can also be used. I did not see success with bread flour but some do.

All-purpose just works the best for my environment. If you are using all-purpose, make sure it is unbleached. 

Whole wheat flour: To get a starter going I do recommend using whole wheat flour for the first day only then after that switching to all-purpose or bread. This is not necessary but I did find when starting with whole wheat it just took off faster. 

Thats it!

Very little equipment and ingredients are needed to keep a healthy starter.

Tips, Tricks and Important Info

Making a sourdough starter is a very simple idea and process. While it requires a little bit of time, it is not difficult at all. 

I have made a few starters, some were major fails and the other was a quick success. The process that I share was the fastest method. 

Here are a few things to keep in mind. 

1. Measure the ingredients in grams. Cup measurements are not accurate and one cup of water is not the same as one cup of flour. 
2. Keep a 1:1:1 ratio. This means you want the same amount of water, flour and starter by weight in grams.
3. Keep the bowl clean. I like to use two bowls or jars to keep my starter in a clean jar to help prevent the growth of mold and bacteria. 
4. Keep it in a warm dry place. Sourdough starters thrive in warmer environments. Keep it in a location that is 70-75 degrees.
5. Store it away from where you prep food. We only want flour, water and the natural environment to affect our starter. If it is around your cooking area, other ingredients might make its way in.
6. Do not put starter in the sink/drain! Make sure when you discard you are throwing it in the trash. When a starter is exposed to air it can become really hard and stick to things. This can cause a blockage in your drain.
7. Do not cover with a tight lid. This can cause the gasses to build up and can end up shattering the jar.
8. Keep the container covered with a light tea towl. I also like to use a flour sack towel. If the towl is too heavy it wont allow the things in that we need.

How to Feed a Sourdough Starter

To get a good active starter it is importan to keep it on a good feeding schedule, especially in the beginning. 

How do you feed a starter? When first starting out, it is so important to remove half (and toss) before feeding with fresh flour and water. This will give that growing culture new food to feed on. Only making it stronger.

For example: Remove half, weigh what is remaining and then feed it. So if you have 100 grams of starter you will want to feed it 100 grams of flour and 100 grams of water. 

Some sourdough bakers will feed by how it feels. This has never worked for me and has left me with an underperforming starter. I swear by the 1:1:1 ratio but do what feels right for you. 

Why do we discard sourdough starter? Half will need to be tossed each time because if we didnt it would grow out of control. Because we are keeping such a small amount there isn't that much that needs to be tossed each time.

After about a week that discard can come in use and can be added to things like pancakes or sourdough waffles. Get all my discard recipes to start using your starter in.

Just the frist week we will want to throw it away. 

How to Make a Sourdough Starter

Let’s get started! Pun intended. 

Day 1:

Take a clan bowl, or jar and place on a digital scale. Set it to gram measurements and make sure it is zeroed out.

Add in 50 grams of whole wheat flour and 50 grams of filtered water.

The whole wheat is just a suggestion. You can also just start with unbleached all purpose. I have made starters both ways and they both turn out great.

Mix it well, cover, and let it sit for 24 hours. Thats it!

Day 2:

After 24 hours of resting this is what it should start to look like. It should be really thick and might even start to develop a crust on top.

It now needs to be fed. Remove half of the starter, leaving about 50 grams.

Add in 50 grams of flour.

Pour in 50 grams of filter water.

Mix, cover and set aside agin for another 24 hours.

Day 3:

This is what it will start to look like. Much different than day 2. You may even start to notice some bubbles.

After another 24 hours, repeat the same feeding process from day two.

Remove half (keeping 50 grams), add 50 grams of flour and 50 grams of water. Mix, cover and rest 24 hours.

As we move into day 4, the cultures are starting to come alive, be more active and need more food. It may even start to smell a bit. That is normal.

Day 4:

From day 4-7 the starter will need to be increased to 2 feedings a day. One in the morning and one at night.

By day 4 it will start to look a lot more alive. It may even have some bubbles. The photo shows what it looked like in the morning of day 4. It is much lighter in consistency and starting to see some bubbles.

Feeding schedule for day 4:

Morning: Discard, feed, and cover.

Evening: Discard, feed, and cover.

By Evening it could look even more alive.

Day 5:

Not much has changed by day 5, but continue with the two a day feedings.

Morning: Discard, feed, and cover.

Evening: Discard, feed, and cover.

Now is a good time to check in. Are you keeping the starter in a warmer location? Is it lightly covered with a tea towel? These things are important when creating a strong starter.

Day 6

By day 6 there seems to be a lot of change. It is getting softer and lighter and developing a crust on top between feedings.

This is normal. The crust just means it needs to be fed. Scrape it off the top and measure out the 50 grams.

Perform two feedings on day 6. Keep 50 grams of starter, feed 50 grams of flour and 50 grams of water.

Morning: Discard, feed, and cover.

Evening: Discard, feed, and cover.

By day 6 begin marking your jar with either a wet erase marker or rubber band. This will make the level of the starter so you can see if there is any growth.

Day 7

Day 7 it's not only looking different it is acting different.

There may be even more bubbles, its really light and there has even been a little bit of growth. It beginning to look like a perform like a starter.

Keep following the same feeding schedule for day 7.

Perform two feedings on day 6. Keep 50 grams of starter, feed 50 grams of flour and 50 grams of water.

Morning: Discard, feed, and cover.

Evening: Discard, feed, and cover.

Day 8

By day eight we had it. Removed the towel to the starter growing over the top of the jar, active bubbles and it was so light and airy.

If your starter is growing and looks alive it is ready to make homemade sourdough bread.

Is it Growing?

By day 7-10 you should start to see some growth in your starter. Using a wet erase marker, or rubber band, mark where you starter is before you feed it.

Check back in 6-8 hours and see if it has grown at all. If it has that means it is alive and active and can added to baked goods without the help of another leaven.

Learn more about how to tell when your sourdough starter is active.

You will have a strong starter when it has doubled or tripled in size in that 6-8 hour time.

After 8 hours you may notice that it starts to defeat and go back down.

This is normal. I just means it consumed all the food and energy and lost that baking potential. No worries just re-feed and watch it grow again.

Once it deflates and goes back down, you now have what is called discard. Learn all about sourdough discard and how to use it.

My Sourdough Starter Still Isn't Rising

If you are not seeing any growth after 10 days do not worry! Some starters just take longer to get going. There are somethings you can try before throwing in the towel.

1. Move back to once a day feedings.
2. Move to a different area of the house. I once tried keeping it in my pantry and it nearly died. It did not survive well in there. Try different areas of your kitchen or even house.
3. Find a warmer location. The ideal temp for a sourdough starter is around 75 degrees. If it is too cold, you may not see any growth.
