I would have to say yes. I’ve been eating handfuls of grapes right off the vine for two days. I began yesterday when I was mowing the lawn in the rain. I’ve had my eye on one of our vines for weeks and every time I’ve tried one of the grapes that seemed like it was changing colors, it was too sour. Well, just yesterday, I hit the jackpot and found a few clusters of purple grapes that were perfectly sweet. So every time I passed by on the lawnmower, I’d grab another cluster of grapes to shove in my mouth. They were so good. I’m telling you.
I have no idea if there are vineyards in Maine. All I know is that we bought a few vines about four years ago in late March from Tractor Supply down in Augusta. We planted four of them next to the fence that surrounds the pool and they did absolutely nothing for three years afterwards. Well, last year they grew slightly. Two vines died, but two vines lived and this year, they grew like crazy and actually produced fruit. The photo above is of a cluster of purple grapes. This is the type I was eating yesterday as I was mowing the lawn. This next type is some sort of red grape. They’re still far too bitter to eat.
The vines have grown so much that they are almost covering the entire fence, which is about 50 feet long. When a grape vine finally grows, it really grows.
I’m pretty excited about having these grapes grow in the property. I’ve seen other more wide grapes growing in the area, but I haven’t eaten any of those. These do have seeds in them, so I basically just suck the juice out of the whole wad I shove in my mouth and then spit it all out after the flavor is gone. I know, gross.
Anyway, if you’re wondering whether or not grapes can grow in Maine, I hope I answered your question.
PS – Japanese Beetles love to eat the grape leaves, so if you would like to grow this fruit in earnest, you’ll have to do something about that.
