growing grapes

[Thomas]

See if you can find the Agricultural Cooperative Extension Service in Michigan--usually run by a university.

Before that, however, you should get a book or two. Grapes Into Wine, by Phillip Wagner, is a good place to start. It's an old book, but it should be available at your library.

Incidentally, just about all grapevines are hybrids of some sort; if you plant a seed, you might get a vine that represents one of the many parents and relatives of the seeds you planted, but you won't necessarily get the vine you wanted. You must use rootstock.
