They were rescued from packaging (someone made a boo boo) My uncle and I share "finds". I've used them before, and they ferment fine. Strain, mash, and use them like fresh. It's been a good year. 450 pounds of pears, 55 pounds of blackberries, 140 pounds of plums, etc, all found their way home. A buddies been making liquers. Have to try some....
