You’ve just made a fresh batch of cannabutter, and now you’re wondering how long it will last in the fridge. It’s a common question among cannabis enthusiasts who enjoy cooking with infused butter. The answer isn’t as straightforward as you might think, as it depends on several factors.
The shelf life of cannabutter is influenced by its ingredients, storage conditions, and how well it is sealed. Cannabutter typically consists of butter and cannabis, which are both perishable items. Butter can go rancid if not properly stored, and cannabis can lose its potency over time.
When refrigerated, unsealed cannabutter can last for about two weeks. However, it’s important to note that during this time, the potency of the cannabutter may decrease. To extend the shelf life, it is recommended to tightly seal the cannabutter in an airtight container or wrap it in aluminum foil or plastic wrap.
If properly sealed, cannabutter can last up to six months in the fridge. Freezing cannabutter can further extend its shelf life, with some sources claiming it can last up to a year or more in the freezer. However, it is important to thaw frozen cannabutter slowly in the refrigerator to maintain its quality.
Overall, it’s best to consume cannabutter within a reasonable amount of time to ensure optimal freshness and potency. If you’re not sure whether your cannabutter is still good, you can give it a sniff test to check for any off odours or discoloration. When in doubt, it’s always better to err on the side of caution and make a fresh batch when needed.
Proper storage of cannabutter
Proper storage of cannabutter is essential to maintain its potency and prevent spoilage. Here are some tips to help you store your cannabutter correctly:
1. Refrigeration: Cannabutter should always be stored in the refrigerator to keep it fresh and prevent bacterial growth. The cool temperature helps to maintain the consistency and prevent mold formation.

5. Keep away from light: Store your cannabutter away from direct light, as exposure to light can degrade its potency over time. Opt for a dark corner in your refrigerator or wrap the container in aluminum foil to protect it.
6. Proper handling: Always use clean utensils when scooping out cannabutter from the container, as introducing contaminants can lead to spoilage. This will help maintain the quality and taste of the cannabutter.
7. Smell and texture check: Before using your stored cannabutter, give it a smell and texture check. If it smells rancid or has an off texture, it’s best to discard it and make a fresh batch.
8. Keep away from pets and children: Cannabutter can be appealing to pets and children due to its aroma and taste. Make sure to store it in a safe place, away from their reach, to avoid any unwanted consumption.
By following these guidelines, you can ensure that your cannabutter stays fresh, potent, and safe to consume for a longer period of time.
Factors influencing the shelf life of cannabutter
When it comes to storing cannabutter, the shelf life can vary depending on several factors. These factors play a crucial role in determining how long the cannabutter will remain fresh and potent. Here are some key factors that can influence its shelf life:
- Storage temperature: The temperature at which cannabutter is stored can greatly impact its shelf life. Refrigerating cannabutter is important to slow down the growth of bacteria and other pathogens that can cause spoilage. It is generally recommended to store cannabutter in the refrigerator at a temperature below 41°F (5°C) to ensure maximum freshness.
- Container type: The type of container used to store cannabutter can also affect its shelf life. It is best to use airtight containers to minimize exposure to air, moisture, and odors that can lead to rancidity and spoilage. Glass jars or plastic containers with tight-fitting lids are commonly used for storing cannabutter.
- Quality of ingredients: The quality of the cannabis used to make the cannabutter can impact its shelf life. Using fresh and high-quality cannabis buds with a good THC content can result in a more potent cannabutter that lasts longer. Avoid using low-quality or old cannabis as it may have less potency and a shorter shelf life.
- Processing method: The way cannabutter is made can also affect its shelf life. Proper decarboxylation, infusion, and straining techniques are important to ensure a longer shelf life. Improper processing methods can result in a butter that spoils more quickly or loses potency faster.
- Exposure to light: Exposure to light, especially direct sunlight or strong artificial light, can degrade the THC in cannabutter. To prevent light-induced degradation, it is advisable to store the cannabutter in a dark or opaque container and in a cool, dark place.
- Frequency of use: The frequency at which the cannabutter is used and exposed to air can impact its shelf life. The more frequently the cannabutter is opened and exposed to air, the more it oxidizes and degrades. It is best to portion the cannabutter into smaller amounts and store them separately to minimize exposure to air.
- Hygiene: Maintaining proper hygiene during the butter-making process and storage is essential for maintaining a longer shelf life. Ensure that all utensils, equipment, and containers used are clean and dry to prevent the growth of bacteria or mold that can spoil the cannabutter.
By considering these factors and taking proper storage measures, such as refrigeration and using airtight containers, you can extend the shelf life of your cannabutter and enjoy its potency and freshness for a longer period of time.
Signs of spoilage
Cannabutter can last for a considerable amount of time when stored properly in the refrigerator. However, like all food products, it eventually deteriorates and becomes unfit for consumption. Here are some signs to look out for to determine if your cannabutter has gone bad:
1. Odor
One of the first signs of spoilage is a noticeable change in the butter’s odor. If you detect a sour or rancid smell, it indicates that the cannabutter has gone bad. Fresh cannabutter should have a pleasant, buttery aroma, so any off-putting smell should be a clear indication of spoilage.
2. Appearance
Another way to determine if cannabutter is spoiled is by examining its appearance. Fresh cannabutter should have a smooth and creamy texture, without any signs of discoloration or mold growth. If you notice any green or black spots, or if the butter appears clumpy or grainy, it is best to discard it.

3. Taste
Deteriorated cannabutter will have a noticeably off taste. If you taste any bitterness, sourness, or a rancid flavor, it indicates that the butter has spoiled. Fresh cannabutter should have a delicious and nutty taste, so any unusual or unpleasant flavors should be a clear sign that it is no longer safe to consume.
It’s important to note that the shelf life of cannabutter can vary depending on factors such as storage conditions and the quality of the ingredients used. It is always best to err on the side of caution and discard any cannabutter that shows signs of spoilage to avoid any potential health risks.
