We have our own grapevines out back. The previous owners planted them. They made wine every year. I love grapes so I was pretty excited when I saw them. You could always look at farmers markets for them.
How hard is it to setup a grapevine? We thought about this not just for wine but for the grapes too. It is one of those tings that comes into the house and goes out of it within a day or so, having a full supply would be great.
