How long are blackberries good for?

The shelf life of blackberries depends upon their condition at the time of purchase as well as the storage conditions in which they are kept.

In the fridge

Blackberries last for about 4-7 days 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 2-3 days to enjoy their optimum quality and taste.

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

At room temperature

Blackberries last for about 1-2 days when kept at room temperature. 

In the freezer

Blackberries, 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 blackberries 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 blackberries in the freezer will increase their shelf life considerably owing to the cool temperature of the freezer that halts the bacterial growth on the blackberries.

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

What is the optimum temperature to store blackberries?

You should always store your blackberries 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 blackberries at a lower temperature to preserve their freshness for a long time.
