Q.Can I Pick My Muscadines Before They Mature?
Yesterday, I looked at my muscadines. They were looking great but weren’t quite ready. This morning, I had lost hundreds of them to the birds. Can I pick my muscadines before they mature? Will they finish the process off the vine?

No, they are not climacteric, and will not ripen after they have been removed, unfortunately.
