I'm not new to fresh fruit and have never had berries do this before. I threw them away, wouldn't even let the birds have them. Theyre not fermenting, as I've forgotten about berries before. I'm not sure what happened. But the person who gave them to me hates me. I didn't eat many of them and didn't get sick but I found it strange they smell like vinegar.

sounds like they started fermenting.
