How Long Does Flour Last? Does it Go Bad?

Flour has been a kitchen staple for centuries, and while it’s long-lasting if stored properly, there is some confusion about how long its shelf life can be in different forms.

Have you ever wondered what the answers to questions like “does flour go bad?” or “how long does flour last?” are?

We’re here to demystify these queries and arm you with all the knowledge necessary to ensure safe storage of this versatile ingredient.

Read on to learn all the facts on flour storage, safety ratings, expiration dates, and more!

What’s Flour?

Flour is a powder made by grinding raw grains, beans, or seeds.

It’s used to make bread, pasta, pastry, and other baked goods.

The type of flour you use depends on the recipe you’re making.

For example, bread flour is made from hard wheat and has a high protein content, while cake flour is made from soft wheat and has a lower protein content.

Flour is one of the most common ingredients in baking, but it’s also one of the most misunderstood.

There are many different types of flour available on the market, and each has its own unique characteristics.

So, how do you know which flour to use for your baking needs?

Here’s a quick guide to some of the most popular types of flour:

  • All-purpose flour: This is the most versatile type of flour and can be used for a variety of baked goods. It’s made from a blend of hard and soft wheat and has a moderate protein content.
  • Bread flour: This type of flour is made from hard wheat and has a high protein content. It’s ideal for breads that require a lot of rising, such as yeast breads.
  • Cake flour: This type of flour is made from soft wheat and has a lower protein content. It’s perfect for tender cakes and pastries.
  • Self-rising flour: This type of flour already contains baking powder and salt. It’s often used for quick breads, such as muffins or biscuits.

How to Store Flour?

When it comes to flour, there are a few things you need to keep in mind in order to ensure that it stays fresh and usable for as long as possible.

For starters, always make sure that your flour is stored in an airtight container.

This will help to keep out moisture and pests that could otherwise ruin your flour.

You’ll also want to store your flour in a cool, dry place – ideally, the pantry or cupboard.

And finally, be sure to label your flour so you know exactly when it was purchased (flour generally has a shelf life of around 6-8 months).

Now that you know how to store flour, let’s talk about how to use it.

Flour is most commonly used for baking, but it can also be used for thickening sauces or gravies, making breading for fried foods, and more.

When baking with flour, always be sure to measure it correctly – too much or too little flour can completely change the outcome of your dish.

And finally, if you’re ever unsure whether your flour has gone bad, give it a sniff – if it smells rancid or off, it’s best to discard it and start fresh.

How Long Does Flour Last?

Flour is a staple ingredient in many recipes, but it doesn’t last forever.

So how long does flour last? And does it go bad? The answer to both questions is “it depends”.

Flour can last for several months if it’s stored properly – in a cool, dry place – but it will eventually start to go bad.

The signs of spoiled flour are discoloration, an off smell, and clumping.

If you see any of these signs, it’s time to toss the flour and get a new bag.

If you don’t use flour very often, you may be wondering if it’s worth the bother to keep it around.

The answer again is “it depends.

” If you only bake occasionally, it might make more sense to buy smaller quantities of flour so that you’re not stuck with a spoiling bag.

But if you do a lot of baking, keeping a big bag of flour on hand can be convenient (and cost-effective).

Just be sure to use it before it goes bad.

Can You Freeze Flour?

Yes, you can freeze flour. Flour will last 6-8 months in the freezer.

Be sure to store it in an airtight container so that it doesn’t absorb any unwanted smells or flavors from your freezer.

When you’re ready to use the flour, thaw it overnight in the fridge before using it in your recipe.

There are a few things to keep in mind when freezing flour.

First, be sure to use a freezer-safe container that is airtight.

Glass jars with screw-on lids work well, as do Zip-loc bags.

Second, write the date on the container so that you know how long the flour has been frozen.

And finally, remember that frozen flour will last 6-8 months, so don’t freeze more than you’ll need during that time period.

Now that you know how to freeze flour, put your newly found knowledge to good use by baking some delicious treats.

How to Tell If Flour is Bad?

The best way to tell if flour is bad is by its smell. If flour smells sour or rancid, it’s gone bad.

Another way to tell if flour has gone bad is by looking for signs of mold.

If you see any mold on the flour, throw it away immediately.

Finally, if the flour has changed color or is clumpy, it’s probably time to toss it out.

If you’re not sure whether flour has gone bad, err on the side of caution and throw it away.

It’s better to be safe than sorry when it comes to food safety.


I hope this blog post has been helpful in answering the question of whether flour goes bad.

Flour has a long shelf life but it can go bad if it is not stored properly.

Be sure to store your flour in an airtight container in a cool, dry place.

If you suspect your flour has gone bad, throw it out and get a new batch.
