Does Butter Go Bad? How Long Is It Good In Fridge 2023?

Many people wonder: does butter go bad? The answer is yes, butter can go bad if it is not stored properly or if it has been kept for too long. Rancid butter can spoil the taste of your dish, and in some cases, it can even lead to health problems.

In this post, PublicanAnker will explore how to tell if the butter has gone bad, the factors that can affect shelf life for butter, and the best ways to store it to ensure its freshness and quality.

Does Butter Go Bad?

Yes, butter can go bad over time. Butter is a dairy product that contains milk fat, and like all dairy products, it is perishable. When butter goes bad, it can develop a rancid taste, and the texture may become grainy or oily. It may also develop mold or a sour smell.

Does Butter Need to be Refrigerated?

Butter can be stored at room temperature for a short period of time, but for longer storage, it should be refrigerated. This is because butter is a dairy product and contains milk fat, which can spoil if left at room temperature for too long.

However, if you plan to consume the butter within a few days, you can leave it at room temperature. Room-temperature butter is easier to spread than cold butter, which is why some people prefer to keep a small amount of butter at room temperature in a butter dish.

If you do choose to keep butter at room temperature, it should be stored in an airtight container to prevent it from absorbing odors from other foods in the area. It is also important to use clean utensils when scooping or spreading butter to avoid contamination.

How Long Does Butter Last in the Fridge?

In the Refrigerator

The shelf life of butter in the refrigerator depends on a few factors, including the type of butter, the freshness of the milk used to make it, and how it is stored. In general, unopened butter can last for several months in the refrigerator typically 1-3 months, if stored properly.

Here are some general guidelines for how long different types of butter can last in the refrigerator:

Salted butter: Unopened salted butter can last up to six months in the refrigerator, while opened salted butter should be consumed within two to three weeks.
Unsalted butter: Unopened unsalted butter can last up to three months in the refrigerator, while opened unsalted butter should be consumed within two weeks.
Flavored butter: Flavored butter, such as garlic or herb butter, should be consumed within one week of opening.

In the Freezer

Butter can last for up to six months in the freezer if stored properly. The key to keeping butter fresh in the freezer is to wrap it tightly in aluminum foil or plastic wrap to prevent exposure to air, which can cause freezer burn.

It’s also important to label the butter with the date it was frozen, so you can keep track of how long it has been stored. When you’re ready to use the butter, it’s best to let it thaw in the refrigerator overnight before using it.

While it may be tempting to thaw it quickly in the microwave, this can cause uneven thawing and can alter the texture of the butter.

How to Store Butter?

To store butter for the best quality and to prevent it from spoiling quickly, here are some tips:

Keep it Cool: Butter should be stored in a cool place to slow down the natural breakdown of the fat. The ideal temperature for storing butter is between 30°F to 40°F (-1°C to 4°C). This can be achieved by storing the butter in the refrigerator.
Use an Airtight Container: To prevent the butter from absorbing odors and flavors from other foods in the fridge, store it in an airtight container. You can also use the original packaging the butter came in, or wrap it tightly in plastic wrap.
Use Fresh Butter: Butter is a perishable item and it can go bad quickly if it is not fresh. Make sure to use fresh butter, and try to buy only the amount you need for the week.
Avoid Exposure to Air: Butter can become rancid when it comes into contact with air. To prevent this, always use a clean knife or butter spreader to cut the amount of butter you need, and immediately return the remaining butter to the fridge.
Keep Away from Light: Butter can also be affected by exposure to light, which can cause it to develop off-flavors. Keep butter in a covered container and store it in a dark place in your fridge.
Freeze Butter for Longer Storage: If you don’t plan to use butter within a week, you can freeze it for longer storage of butter. Wrap the butter tightly in plastic wrap or foil, and place it in an airtight container before freezing. Frozen butter can be stored for up to six months. When you’re ready to use it, simply thaw it in the refrigerator overnight.

Can I Keep Butter On The Counter and How to Store Butter Without Refrigeration? (on the counter)

It is not recommended to keep butter on the counter for extended periods of time, as it can spoil quickly due to exposure to air and heat. However, if you want to store butter without refrigeration for a short time, such as a day or two, there are a few methods you can try:

Use a butter crock: A butter crock is a ceramic dish that has two parts – a lid and a base. The base is filled with cold water, and the butter is placed in the lid, which is then submerged in the water. This creates an airtight seal that keeps the butter outside of fridge fresh for several days.
Use a butter bell: A butter bell is similar to a butter crock, but it has a different design. The butter is placed in a small dish that fits inside a larger, inverted dish. The larger dish is filled with water, creating an airtight seal that keeps the butter fresh.
Use ghee: Ghee is a type of clarified butter that has had the milk solids and water removed. It has a longer shelf life than regular butter and can be stored at room temperature for up to several months.

Regardless of which method you choose, make sure to use clean utensils when handling the butter to prevent contamination, and discard any butter that appears discolored, has an off smell, or tastes rancid.

Do I Store Salted Butter Differently from Unsalted Butter?

Salted butter and unsalted butter should be stored in the same way. Both types of butter should be stored in the refrigerator to keep them fresh and prevent spoilage. The ideal temperature for storing butter is below 40°F (4°C).

Keep butter in an airtight container or wrapped tightly in foil or plastic wrap to prevent exposure to air, which can cause the butter to become rancid or develop off-flavors.

If you want to freeze butter for longer-term storage, it is best to wrap it tightly in foil or plastic wrap to prevent freezer burn.

When it comes to cooking and baking, it is important to note that salted and unsalted butter are not interchangeable in recipes, as the salt content can affect the flavor and texture of the finished product.

How Long is Butter Good for After the Expiration Date?

It is generally not recommended to consume butter after the expiration date, as it can pose a risk of foodborne illness.

The expiration date on butter is a guide to the product’s quality and freshness, and consuming expired butter can lead to spoilage, bacterial growth, and food poisoning.

While some types of food can still be safe to consume after the expiration date if stored properly, it is not recommended to take chances with butter, as it can quickly spoil and become rancid.

It is best to check the expiration date on butter before purchasing it and to consume it before the expiration date to ensure its freshness and quality.

How to Tell If Butter Is Bad

Check the expiration date: If the expiration date on the butter has passed, it may have gone bad and should be discarded.
Look for discoloration: If the butter has yellow or brown spots, it may have started to spoil.

Check the texture: Fresh butter is smooth and creamy, while butter that has gone bad may have a grainy or lumpy texture.
Taste a small amount: If the butter tastes sour, bitter, or rancid, it is no longer good and should be discarded.

If you notice any of these signs of butter rancidity, it is best to err on the side of caution and throw out the butter. It is always better to be safe than sorry when it comes to consuming spoiled food, as it can cause food poisoning and other health problems.
