Blackberries stay fresh for about 3 to 7 days in the refrigerator under the right conditions.
If you’ve ever wondered how long do blackberries stay fresh after bringing them home from the store or picking them fresh, the answer depends on a few key factors.
Fresh blackberries can stay fresh for just a couple of days at room temperature, but once you refrigerate them properly, they can last up to a week or sometimes a little longer.

How Long Do Blackberries Stay Fresh?
Blackberries stay fresh for different lengths of time depending on where you keep them.

In the freezer, blackberries stay fresh for up to 6 to 12 months.
Freezing doesn’t keep them fresh in the traditional sense, but it preserves them so they don’t spoil.
