Does Butter Really Expire?
Butter does have an expiration date and can go bad or spoil if not stored properly. The shelf life of butter depends on the type and how it is stored. Unsalted butter can last for a few weeks at room temperature and up to three months in the fridge, while salted butter can last a bit longer. Freezing butter can also extend its shelf life for several months. It’s essential to check for signs of spoilage, such as discoloration, a rancid smell or taste, or mold, before consuming expired butter.
