Does Brown Sugar Go Bad? – Full Analysis

Brown sugar can be an integral ingredient when it comes to baking or preparing a dish that requires this type of sucrose sugar. Brown sugar is different from white sugar, most notably because of its color. The brown color is actually a result of the presence of molasses.

Does brown sugar go bad? No, brown sugar does not go bad. If it is stored away correctly and kept in an airtight container, it will last indefinitely. Brown sugar, like rice, beans, honey, or salt, lasts for a long time if it is protected by air, moisture, and bugs. Without perfect storage, most bags of brown sugar can still last 5 years despite most expiration dates between 1-2 years.

The expiration date printed on the bag is just a regulation rule created by the FDA. If you have a packet of brown sugar that is hard, it does not mean that the sugar has gone bad. It just means that the sugar lost some moisture, and its softness can be restored. 

How Long Does Brown Sugar Last?

Brown sugar has a very long shelf life. Its shelf life is comparable to canned goods, beans, and rice. As long as the sugar is in an airtight container and kept safe from air, moisture, and bugs, it can last almost indefinitely. 

Its natural long shelf life means that brown sugar can last for ten or more years, possibly even a hundred years. We are not exaggerating!

Although, you may not want to store a cheap bag of brown sugar from Walmart in a bank vault for one hundred years. The indefinite length of storage time mostly applies to high-quality brown sugar without any additives or extra ingredients. 

A regular bag of brown sugar will last for a good five years. However, the manufacturer who produces brown sugar will put the expiration date at 1-2 years on the packaging. 

The expiration date is because FDA regulations state that all things must have an expiration date. But brown sugar can still last beyond these dates.

How to Know if Brown Sugar has Gone Bad?

Like plain white sugar, brown sugar has a very long shelf life. The high amount of moisture in the brown sugar will make it stay incredibly soft and malleable as long as it is in an airtight container. Most packages of brown sugar do not have preservatives as part of their ingredients, so it is not protected from spoiling if something goes wrong.

When brown sugar rots, it will change into a different color. The color turns depending on its moisture content. The color change will be most noticeable around the edges of the package. For some packages of brown sugar, the color will turn pale or white. However, if a package of brown sugar starts to turn darker than its original color, then that is also a sign of rot.

One more way to tell if a brown sugar package is old is by its stickiness. Brown sugar has natural moisture in it, but it should never be sticky or slimy. If you touch some brown sugar and a sticky film left on your fingers, there is too much moisture in the brown sugar, and it has gone bad. 

If Brown Sugar is Hard – Did it Expire?

Brown sugar that has turned completely hard is still perfectly safe to eat. Many people think that because brown sugar is hard, it has become stale and is no longer edible. But that is just not true. 

Because of the high moisture content in brown sugar, it is very soft compared to white sugar. However, if the bag has a hole or is exposed to too much air, it can lose its moisture. But losing moisture does not mean it has gone bad. Most brown sugar packages will get hard from time to time. 

When you have a hard package of brown sugar in your pantry, the first thing you need to do is place it in a grocery bag or a large Ziploc bag and smash it on the ground. The impact will cause the brown sugar to break apart, so you can soften it into smaller pieces.

You can then take a piece out of the package and wrap it in a damp paper towel. The paper towels should not be dripping with water as that will ruin the brown sugar and make it sticky. 

Place the brown sugar wrapped in a damp paper towel and put it in the microwave. Microwave the sugar for 20 seconds. When finished in the microwave, squish and mash the brown sugar, so it softens completely

If the sugar is too hot, then you can use a fork to mash it. If it is still hard, then microwave it again for 10 seconds. After you are finished microwaving it, the brown sugar should be soft and ready to be added to any recipe.

How to Store Brown Sugar

How you store your brown sugar depends on what you intend to do with it. If you plan to use it for everyday cooking and baking, brown sugar can sit in a cupboard or pantry or in its original packaging. 

Remember that you can also put brown sugar in the fridge if your house retains a lot of heat or if you have a bug issue. While it is in the refrigerator, it can be kept in a bag or a container. Just be sure to protect the brown sugar from air or moisture. 

If the brown sugar is meant for long term storage, then it must be in a container that it will protect it from the sun and the air. A thick glass jar with a suction seal lid is good as well. 

It is unnecessary to freeze brown sugar since it lasts so long all by itself at room temperature. But you can freeze the sugar if you want to. Like storing it in the fridge, brown sugar in the freezer must be in an airtight container, so it is not vulnerable to freezer burn.
