Why do you need a sourdough starter?

A sourdough starter is a continually maintained mixture of wild yeast and suitable bacteria used to seed fermentation in new dough for bread, pastry, and more.

How long does it take for a sourdough starter to be ready?

In general, I’ve found it takes about 7 days from when you first mix flour and water to when a sourdough starter is ready to be used to bake bread.

Is a homemade sourdough starter safe?

A well-maintained sourdough starter can live virtually indefinitely. The high-acid environment of the sourdough starter helps stave off any unwanted pathogens. However, if you see any signs of traditional mold (pink, white fuzzy, green), it’s best to discard the entire starter and start a new one.

Should I make or buy a sourdough starter?

While buying a sourdough starter is very easy online, it’s a very easy process to do at home! Plus, creating your own starter exposes you to the signs of fermentation, what steps you need to perform to maintain your starter, and gives you a chance to get to know the feeding (refreshment) process.

How long does it take for a sourdough starter to peak?

Some bakers use the term “peak” to refer to either the point at which a starter is ready to be used or needs feeding, or it can refer to the physical peak height of the starter in the jar. I find judging a sourdough starter’s readiness based solely on the height it has risen to may lead to using it at an incorrect time. After all, the height of a starter is simply a display of the strength and other characteristics of the flour. To determine when your starter is ready to be fed (or used for baking), look for a combination of signs: some rise, bubbles on top and at the sides, a sour aroma, and a loose consistency (it should loosen the longer it ferments). From there, use the timeframe for fermentation as a guide: at about 72-78F (22-25C) with 30-50% whole grain flour and 20% ripe starter (the seed, or inoculation), it might be ready after 12-16 hours.

Why doesn't my sourdough starter have big bubbles?

It's okay if your starter doesn't have big bubbles. Large bubbles can be the result of the flour you're using and the hydration. What's more important overall, is to see strong signs of consistent fermentation: some bubbles, consistent rise each day, a sour aroma, a loosening in texture.

Why is my sourdough starter not rising?

It's worrisome if you don't see any rise in your starter, you should see some. Usually, no rise is a sign it's not fermenting properly and needs more time to establish. Continue with the feeding schedule outlined in my guide on how to make a sourdough starter and it should begin fermenting after a few days.

Making an Incredible Sourdough Starter from Scratch in 7 Easy Steps

Description

This sourdough starter recipe will help you create your own sourdough starter from scratch at home in seven easy steps. Your starter is the cornerstone of great bread—once you have it showing consistent signs of fermentation each day, which takes on average 5 to 7 days, you’re ready to start baking sourdough bread!

Ingredients

300g all-purpose flour
400g whole-grain rye flour
800g water

Cook Mode Prevent your screen from going dark

Instructions

Day One
To a clean jar, add 100g whole rye flour and 125g warm water. Mix ingredients and keep somewhere warm for 24 hours.
Day Two
To clean jar, add 75g of the mixture from Day One (discard the rest), 50g whole rye flour, 50g all-purpose flour, and 115g water. Mix ingredients and keep somewhere warm for 24 hours.
Day Three
To a clean jar, add 75g of the mixture from Day Two (discard the rest), 50g whole rye flour, 50g all-purpose flour, and 115g water. Mix ingredients and keep somewhere warm for 24 hours.
Day Four
On day four, you will give the mixture two feedings. In a clean jar, add 75g of the mixture from Day Three (discard the rest), 50g whole rye flour, 50g all-purpose flour, and 115g water. Mix and let rest for 12 hours. In the evening, after 12 hours, repeat the discarding and feeding you did in the morning. Let the mixture rest overnight.
Day Five and Six
For days five and six, continue to discard down the jar contents and then feed with the same ratio of ingredients as Day Four, twice a day. You can use the same jar for these feedings.
Day Seven and Onward
In the morning on Day Seven, discard the jar’s contents down to 20g of the mixture and add 30g whole rye flour, 70g all-purpose flour, and 100g water. Repeat this feeding twice a day, once in the morning and once in the evening, indefinitely.

Notes

You don’t have to use a new, clean jar each time you feed your starter, but I find it’s helpful to keep track of the weight of the jar so you know how much you’re carrying over.
