I'm new to growing grapes and am looking for some opinions.

According to Wiki, wine grapes tend to be sweeter than table grapes but have less flavor. Is this true?

Other than 'less flavor', are there any other issues involved in using wine grapes for the table?

My grapes are protected inside a hoop house over winter and I have room for a few more grape vines. Any recommendations for a really sweet grape will be greatly appreciated.
