FWIW that was in the early 90’s. I picked 23 pounds of blackberries and stuck them in the freezer. I was so thunderstruck with the bounty of wild berries that grow here after living in Colorado for years I couldn’t waste them.It didn't go anywhere, haha! That's a terrific find! I also didn't realize corks came in different sizes, I don't think we'd have been able to shove those #9's or whatever the number was in with a hand one.
So my aunt brought her potato masher over and we smashed them up and made wine! I think there might still be a bottle down there somewhere. Last one I brought up sat in the kitchen a couple days and had a secondary ferment start.It blew the cork out no kidding and the glass or two that remained was actually really good.
