Why I Have Concerns About Oat Milk
How Long Can Oat Milk Last in the Fridge
If you’re like me, you never really know how long milk will last in the fridge. I’ve been known to leave a carton of oat milk in the fridge for months, only to find out it’s gone bad when I try to use it. So, how long can oat milk last in the fridge?
The answer may surprise you. Oat milk can actually last quite a while in the fridge. In fact, some sources say that it can last up to two weeks after being opened.
However, this is only if it’s stored properly. If you store oat milk in an airtight container and keep it away from light and heat, it will last much longer than if you just leave it out on the counter.

Does Oat Milk Need to Be Refrigerated After Opening
If you’re like most people, you probably keep your milk in the fridge. But what about oat milk? Does oat milk need to be refrigerated after opening?
The answer is yes, oat milk does need to be refrigerated after opening. Just like any other type of milk, oat milk can spoil if it’s not kept properly refrigerated. So, if you’re going to drink oat milk, make sure to store it in the fridge and drink it within a few days of opening it.
Of course, you can also freeze oat milk to extend its shelf life. Just pour the desired amount into an ice cube tray and freeze. Then, when you’re ready to drink it, thaw the cubes in the fridge or microwave.
Left Oat Milk Out for 5 Hours

But how long can milk actually sit out before it goes bad?According to the USDA, milk should not be left out at room temperature for more than two hours.
After that, bacteria can start to grow, and the milk can spoil. If you do accidentally leave milk out for longer than two hours, it’s not necessarily unsafe to drink. However, it will probably have an off flavor and may cause digestive upset.
So what should you do if you find yourself with milk that’s been sitting out for too long? The best option is to simply toss it and start fresh. But if you’re really attached to that half-gallon of oat milk, there are a few things you can try to salvage it.
First, boiling the milk will kill any harmful bacteria present. Additionally, adding a bit of acidity (like lemon juice or vinegar) can help counteract some of the off flavors caused by spoilage.
If in doubt, throw it out!
