How to Tell if Oat Milk has gone bad?

Oat milk is a popular alternative to animal milk because it is better for the environment and health. However, oat milk has a shorter shelf life – only about 7-10 days after opening the can if stored in the refrigerator. After this time, you should check, smell or taste the milk to see if it has gone bad. If not, you can still drink milk; on the contrary, give up milk now!
