Answer: Fortunately (or unfortunately) you live in a climate that supports lots of fruit on grapevines. If you're not interested in fruit, there are a few plants that you can substitute for grapevines such as hops, or you can choose a grape variety that requires more heat than your growing area provides in order to produce fruit. Or, you can prune your grape vines to reduce the amount of fruit it is capable of producing. European grapes require the most summer heat and they produce on fruiting spurs. If you were to plant 'Csaba' or 'Pearl of Csaba' and carefully remove the fruiting spurs each year, you would have little, if any fruit. Hope this information helps you decide what to plant!
