How long will frozen blackberries last?

Answer 1

Roughly 3 or 4 days, tops. Berries go bad quickly. You can double that by using those "green" bags that extend the shelf-life of produce. Also, the berries on the bottom of the carton, which have been crushed, are the first to go, and also the first to start developing mold. At the three-day mark, the bottom may be trash but the berries on the top may still be edible. If any berry is not whole, or is crushed, discard it.

Answer 2

I've stored mine for a year and they still made a good cobbler and great jam.

Answer 3

Up to three months IF your freezer is a four-star one - otherwise, follow your manufacturers recommendations.

Answer 4

You can keep about 1-3 months. Black berries aren't really good when you keep them in the freezer to long.

Answer 5

As long as you want.
