Butter can go bad – if you store it wrong. We explain how to recognize this and give you tips for the right storage.
Can butter go bad?
If you store it incorrectly, butter can go bad quickly. According to the consumer advice center, butter only lasts a few days at room temperature, for example, while it can be kept for several weeks in the refrigerator and even months in the freezer. If you are unsure whether you can still eat butter, trust your senses.
Signs such as a sour odor, dark yellow discoloration, and rancid taste can indicate the butter has gone bad. If you can identify the characteristics mentioned in your butter, you must throw it away. According to the consumer advice center, harmful decomposition products can arise during the decomposition process.
Note: An expired best-before date alone says nothing about whether the butter is still good. After all, this is not a use-by date like meat, but merely an orientation for you as a consumer.
Storing butter correctly: This is how it works
So that your butter does not go bad, you should store it properly:
Keep the butter as cool as possible, preferably in a sealable container in the butter compartment of the refrigerator.
Alternatively, you can freeze them in small portions.
If you want to spread the butter on your bread, for example, make sure you use a clean knife.
Incidentally, these storage tips can also be applied to margarine.
If you buy butter, you should pay attention to organic quality. This is how you support species-appropriate animal husbandry. The Naturland, Demeter and Bioland seals have particularly strict requirements. You can also make your own butter.
The same applies to margarine, which is even more environmentally and animal-friendly in production because it is mainly derived from plants (and vegan margarine is entirely plant-based). Margarine is particularly sustainable if it contains no palm oil.
