How Long Does Sourdough Bread Last and How to Extend Its Shelf Life?

Sourdough bread has been a popular food item for centuries, known for its unique tangy flavor and chewy texture. But how long does sourdough bread last? Unlike regular bread, sourdough is made from a naturally fermented dough that contains live yeast and bacteria.

As a result, it can last longer than most other types of bread. However, its shelf life can still be affected by various factors, such as how it’s stored and the environment it’s kept in.

In this article, we’ll explore the shelf life of sourdough bread and the best practices for keeping it fresh for as long as possible. So, if you’re a fan of sourdough bread and want to know how to make it last, keep reading!

If wrapped and appropriately stored, sourdough bread lasts 3 to 5 days. The best way to enjoy sourdough is to eat it within 24 hours of making it. So, you can enjoy the crispy crust and soft, airy interior to the fullest.

An adequately stored loaf of bread will deliver good taste and flavor even after a long time. As a matter of fact, store-bought bread does not have the same shelf life as fresh sourdough bread (bread made from a sourdough culture).

Don’t refrigerate your bread, no matter what you do. This will accelerate the staleness of your bread. You’ll want to approach bread storage differently depending on how recently your bread was baked.

What Is The Shelf Life Of Sourdough Bread?

No preservatives or artificial improvers are added to sourdough bread, so its shelf life is relatively short.

Because sourdough bread has a shelf life and is actually considered fresh for a different amount of time, we need to differentiate between the two.

Despite the fact that sourdough bread doesn’t mold during the first 24 hours, it is not considered fresh after that time.

It is edible for around three days. On the third to fifth day, it should be toasted or warmed before eating. The sourdough bread will be stale (but not moldy) after five days.

How Long Does Homemade Sourdough Bread Last?

To give you a quick overview of how long sourdough bread will actually last, here is a quick summary:

First 24 hours. – This is when sourdough is considered fresh. Deliciously crisp crust & soft interior, freshly baked aroma.

Does Sourdough Bread Last Longer Than Regular Bread?

The lactic acid bacteria in sourdough bread help it stay fresh and soft longer than regular store-bought bread, but it doesn’t last as long because it lacks preservatives.

Trying to explain how sourdough bread differs from regular bread can take time and effort. Also, we have to clarify whether “regular” bread is made with homemade yeast or if it is a commercially made loaf with added preservatives and improvers.

Things That Can Shorten The Shelf Life Of Sourdough Bread

A number of factors can prevent you from eating fresh bread when it comes to sourdough bread. Temperature and humidity contribute to the shortening of shelf-life; high temperatures foster bacterial growth, which causes food to spoil quickly.

When the loaf is exposed to air, it loses its freshness; an aluminum foil or ziplock bag package will extend its shelf life. The final step is to store the bread in an airtight container that will keep out the air and protect it from the elements.

The shelf life of sourdough bread at room temperature is between 5-10 days when it is properly stored. You can extend the life of your produce by storing it in an airtight bag or container.

Can I Freeze Sourdough Bread?

Storing sourdough bread in the freezer would be the best option if you have yet to eat it after ten days. There is no problem with freezing individual slices of sourdough bread.

If you freeze them as slices, they may get freezer burn if you leave them in for too long. The advantage of frozen pieces is that they can be toasted without defrosting.

To reheat frozen sourdough bread, take it out of the freezer and place it in a 325F oven for 15-30 minutes. Your artisan bread will be able to develop a crisp crust this way.

How To Make Homemade Sourdough Bread Last Longer?

It is possible to extend the shelf life of homemade sourdough bread by making it yourself.

The fermentation process in homemade sourdough bread preserves the flavor and texture of the bread for 10-14 days when stored correctly.

In the meantime, wrap the loaf in foil and heat it for 10 minutes to refresh it. Let the loaf cool completely before enjoying it.

When stored properly at room temperature, sourdough bread lasts up to ten days. If it’s going stale, it can also be frozen or reheated in the oven. Take comfort in knowing that you can extend the life of your sourdough bread.

What To Do With Stale Sourdough Bread?

There may be times when your bread becomes stale. How can we use old sourdough bread? Here are some suggestions:

  • Make garlic bread – Butter and garlic can breathe new life into old sourdough bread. You can use olive oil to reduce the staling process if you prefer a different taste.

How Long Does Sourdough Last In The Freezer?

It is possible to store sourdough in the freezer for a long time, provided it is packaged properly.

A sourdough loaf will last up to 6 months without any issues, although once defrosted, it will start losing some flavor, crust, and crumb after some days.

For successful freezing of sourdough, properly wrap it. For freezing sourdough, you’ll need aluminum foil, plastic wrap, and a heavy-duty freezer bag.

Does Sourdough Last Longer At Room Temperature?

Yes, sourdough bread is always best stored at room temperature. You may be able to keep your sourdough culture in the refrigerator, but a loaf of sourdough bread is stored best at room temperature.

If you are storing sourdough, you may want to put it in a plastic bag, brown paper bag, or even a bread box, depending on the type of bread. I’ve compiled a guide to storing.

It is important to consider humidity levels when storing sourdough bread. Sourdough bread shouldn’t be stored in plastic bags or plastic wrap if you live in humid areas, as it will lead to early mold growth.

It is still recommended that you never refrigerate sourdough bread, even in very humid conditions. This dries the bread out and makes it stale faster than leaving it at room temperature.

It would be better to freeze sourdough than to put it in the fridge if you really can’t allow it to sit at room temperature.

How Do You Know When Sourdough Has Gone Bad?

It is easy to tell when sourdough bread is going bad since it will show visible mold growth and feel hard both inside and out. A bad smell may also accompany it, but this is only sometimes the case.

The crust and crumb will deteriorate once it has passed the fresh stage (first 24 hours). By day three, the crust is usually very hard and makes it difficult to cut the bread – but it can still be consumed if toasted or heated.

Identifying mold is easy. Sourdough bread mold is usually green or white and fuzzy, just like sourdough starter mold. Moldy sourdough bread should be disposed of and never eaten.


Sourdough bread is a delicious and nutritious food that can last longer than other types of bread due to its unique fermentation process. However, its shelf life can still be affected by various factors, including storage conditions and the environment it’s kept.

To make your sourdough bread last longer, you must store it properly and keep it away from moisture and heat. By following these tips, you can ensure that your sourdough bread stays fresh and tasty for as long as possible.

So, the next time you make or buy a loaf of sourdough bread, keep these factors in mind and enjoy every slice without worrying about its shelf life.
