Flour Basics
Flour is a staple ingredient in many recipes, but how long does it last? Flour made from wheat can last up to six months if stored in a cool, dry place, like a food-grade bucket. But if you store your flour in a damp environment, it will only last for about a month.
Flour types
There are many types of flour available on the market today, which can be confusing for a baker. Here is a quick guide to the most common types of flour, so you can choose the right one for your recipe.
All-purpose flour: This is the most common type of flour, and it can be used for most baked goods. It is made from a blend of hard and soft wheat and has a moderate protein content.
Bread flour: Bread flour is made from hard wheat and has a high protein content, which gives bread its chewy texture. It is not suitable for cakes or other delicate desserts.
Cake flour: Cake flour is made from soft wheat and has a low protein content. It is very fine and will give your cakes a tender texture.
Self-rising flour: This type of flour already contains baking powder and salt, so it should not be used in recipes that call for those ingredients separately. It is often used to make quick breads and biscuits.
How flour is made
It all starts with the wheat. The wheat kernel (or berry) is made up of three parts: the endosperm, bran and germ. Wheat flour is made from the endosperm only. The germ and bran are removed in a process called milling, which produces what’s called “white flour.”
Different types of wheat flour have different gluten-protein content, which affects the ‘rise’ or ‘fluffiness’ of baked goods made with that flour. For example, bread flour has a higher gluten content than pastry flour, so it will produce taller, lighter loaves of bread. Flours with lower gluten contents will produce shorter, denser baked goods.
Storing Flour
If you purchase flour in bulk, you’ll want to store it in a food-grade bucket to keep it fresh. How long does flour last in these containers? With proper storage, flour can last up to six months in a food-grade bucket. We’ll talk about the best storage practices for flour, so your supply will be fresh when you need it.
Best practices for storing flour
Whether you’ve just bought a new bag of flour or you’re trying to figure out how to best use up an old one, it’s important to know how to store it so that it will stay fresh for as long as possible. Flour does have a shelf life, and proper storage will help it last longer.
Here are some tips for how to store your flour:
- Store flour in a cool, dry place. Heat and moisture will cause flour to go rancid and spoil more quickly.
- If you plan on using your flour within six months, storing it in the pantry in a food-grade container is fine.
- For longer storage, up to one year, store the flour in the freezer in a food-grade container. Be sure to label the container with the date so you know when it needs to be used up.
- If you have any opened bags of flour that are past their expiration date, it’s best to throw them away. following these tips will help ensure that your flour stays fresh and usable for as long as possible.
How to store flour for long-term storage?
There are several things to consider when it comes to storing flour for long-term storage: moisture, temperature, light and pests.
Flour should be stored in a cool, dry place. The ideal temperature is between 40-60 degrees F. If the temperature is too warm, the flour will start to go rancid; if it is too cold, the flour will become hard and difficult to use.
Flour should also be stored in an airtight container. This will help to keep out moisture and pests. If you are using a food grade bucket, make sure to put a layer of food grade plastic down before adding the flour. This will help to keep the flour from absorbing any odors from the bucket.
Finally, flour should be stored away from light. Light can cause the flour to go rancid more quickly. If you are using a food grade bucket, you can store the flour in a dark closet or cupboard.
Shelf Life of Flour
Flour has a long shelf life and can be stored in food grade buckets for years. The main thing to keep in mind when storing flour is to keep it away from moisture and heat. If flour becomes moist, it will spoil and if it gets too hot, it will lose its nutritional value.
How long does flour last unopened
Flour has a long shelf life but goes bad eventually. Most types of flour last between 3 and 8 years when stored properly in the pantry. All-purpose flour, whole wheat flour and white flour have different timelines though, so pay attention to the type you have on hand.
all-purpose flour: 2 to 3 years
whole wheat flour: 6 to 8 months
white flour: 1 year
How long does flour last opened
Unopened, all-purpose flour lasts 6-8 months past its printed date, while unopened cake flour lasts up to one year. However, we want to emphasize that these are estimates only. All-purpose flour and other wheat flours will last longer if stored in the freezer (up to one year).
Once opened, all-purpose flour should be used within 3-4 months. We do not recommend storing all-purpose or any wheat flour in the fridge or freezer due to the potential for moisture buildup, which can cause mold or other spoilage.
Using Old Flour
Using flour that is too old can result in sub-par baked goods. The main signs that your flour has gone bad are if it has changed colors or smells strange. If your flour is more than a year old, it’s best to throw it out.
How to tell if flour has gone bad
Flour is a staple ingredient in many kitchens, but it doesn’t last forever. In fact, it has a relatively short shelf life compared to other pantry staples. So how can you tell if your flour has gone bad?
There are a few key indicators that your flour may be past its prime:
-The color of the flour has changed. If your flour is starting to look gray or yellow, it’s time to toss it.
-The texture of the flour has changed. If your flour is starting to feel clumpy or hard, it’s time to toss it.
-(If you’re using self-rising flour) The leavening agent in the flour is no longer active. If your self-rising flour isn’t rising anymore, it’s time to toss it.
If you see any of these signs, it’s best to err on the side of caution and throw out the flour. It’s better to be safe than sorry when it comes to food safety!
What to do with old flour
There are a few things to consider when you are trying to use old flour. The first is the type of flour. Flour can be all-purpose, self-rising, bread, pastry, or cake flour. The second is how the flour has been stored. Flour can be stored in a food grade bucket with a lid, or in a sealed bag or container. Finally, you need to consider the age of the flour. All of these factors will affect how the flour behaves when you try to use it.
- All-purpose flour: This type of flour can be used for most baking needs. If it is more than a year old, it may not rise as well as fresh flour, so you may need to use more yeast or baking powder.
- Self-rising flour: This type of flour already has baking powder and salt added to it. If it is more than a year old, the baking powder may not be as effective, so you may need to add more.
- Bread flour: This type of flour is higher in protein and gluten, which gives bread a chewy texture. If it is more than a year old, it may not rise as well or be as tender as fresh flour.
- Pastry flour: This type of flour is lower in protein and gluten than all-purpose or bread flour. It is often used for delicate pastry crusts. If it is more than a year old, it may not be as tender as fresh pastry flour.
- Cake flour: This type of flour is even lower in protein and gluten than pastry flour. It makes very light and tender cakes. If it is more than a year old, it may not produce cakes that are as light and tender as those made with fresh cake

In general, you can use old flour if it is less than a year old and has been stored properly (in a food grade bucket with a lid or in a sealed bag or container). However, the older the flour is, the less likely it is to work well in recipes .
