Hi, Well to be of much help, I'll need a bit more information. First of all, do you know what kind of grapes you have? Second, where are they growing? For example, are they getting enough sunlight because grapes need at least 6 to 8 hours of direct sun a day to produce fruit. So, repost and let me know what grapes you planted (also keep in mind that some types take a number of years to mature enough to even bear fruit) and the situation they are growing in and I'll try to help.
