Blackberries have one of the highest antioxidant levels of all fruits.

Store fresh blackberries in the refrigerator, unwashed, in their original container or a plastic bag, and use within three to five days. Wash just before eating. For longer storage, freeze them in an airtight container or freezer bag for up to a year.
