How long are blueberries good in the fridge?

Blueberries last for about 1-2 weeks if stored at or below 40 degrees Fahrenheit in the fridge. They should be stored in plastic bags having small holes for ventilation on one of the shelves of the refrigerator. But it is recommended to use them within the first week to enjoy their optimum quality and taste.

Moreover, you can even line up the packaging with paper towels to soak extra moisture. 

It is worth mentioning that it is better to wash the blueberries just when you are ready to eat them.

How long are blueberries good for at room temperature?

Blueberries last for about 2-3 days when kept at room temperature away from direct sunlight and heat. 

How long are blueberries good for in the freezer?

Blueberries, if kept in an air-tight container or air-tight plastic freezer bag, can last for up to 10-12 months in the freezer. 

So what you gotta do is to wash the blueberries in cold water and pat them dry using paper towels. Now line them up in the cookie tray and let them freeze in the freezer. Once they have frozen, transfer them to the plastic freezer bag, label it and store it in the freezer.

Thus keeping the blueberries in the freezer will increase their shelf life considerably owing to the cool temperature of the freezer that halts the bacterial growth on the blueberries.

When it comes to thawing, you can defrost the blueberries easily by leaving them in the fridge or a bowl of water. In case you are planning to make a blueberries smoothie, you can skip thawing and can use the frozen blueberries directly.

What is the optimum temperature to store blueberries?

You should always store your blueberries at 40 degrees Fahrenheit or below. Bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore it is always advised to store your blueberries at a lower temperature to preserve their freshness for a long time.
