Is Sourdough Gluten Free?


I get quite a few questions about whether long fermented sourdough bread is considered gluten free. Although the answer is NO, there is more to the answer that I want to share with you.

First, let’s talk about Sourdough and the process of fermenting your grains. Sourdough starter is a colony of yeast and bacteria. When you make a starter, you are capturing this yeast and bacteria from the air, the flour, and even the utensils you use.

When you make bread using a sourdough starter, there is a long rise time. This is called the fermentation process. In general, it takes anywhere from 4-24 hours to fully ferment a loaf of sourdough bread.

During this time, there is a breakdown of the gluten in the dough. And, although it doesn’t render the bread gluten free, it can be tolerated more easily by gluten sensitive people.


Celiac patients can not tolerate even a small amount of gluten. However, wheat sensitive and gluten sensitive people have reported being able to tolerate sourdough bread that has been fermented for at least 12-24 hours.

This is great news for those who suffer with bloating and stomach issues after eating bread.

To make things even better, when you use freshly milled flour to make your sourdough, the vitamins and minerals are more bioavailable if you long ferment them with sourdough.

I think we are all in agreement that we want to feed our families the most nutritious food we can. Freshly milled sourdough bread is kind of a super bread. Full of nutrients and easier to digest, this bread is also the most flavorful of all!

I love to make sourdough bread with freshly milled ancient wheat. These heritage wheat varieties are already easier to digest than their modern counterparts and are also much more flavorful.

To summarize, if you are someone who deals with tummy issues after eating bread, I highly recommend looking into long fermented sourdough bread.
