I have a woody vine growing on the back of my house that sprouted up on its own. this is the 5th year and it looks like it is growing clusters of grapes. I have tried to locate the name and look a like but the leaves look nothing like a wild grape. I have pics of the fruit, leaves and the inside of the fruit. the fruit is about 1/4 in. also, are the fruit eddible?

Here is a link that might be useful: 3 pics of unidentified vine
