Unlike the orchard, I did not seek outside guidance on my grape vines until the year where the entire, luscious tangle of vines sprouted powdery mildew.
Learn from my mistakes - mainly that grapes LOVE and NEED to be pruned, like a lot more than anything else I've ever grown. But worry not my friends, the pruning goes quick and pay bountiful dividends. The year I did no pruning got me something like 5 pounds of grapes, last year I hauled in over 25 pounds.
So here's the scoop - you will likely feel like you are taking so much of the plant that there is no way it will come back, but that feeling probably means you took just enough. Grapes love to be pruned back by about 2/3's of the new growth from the prior year. In a nutshell, old growth looks like papery bark, peeling and falling away from the vine and new growth looks like brown, spidery vines. Look up photos to be certain before you start cutting, but chances are that if this is your first time, you're in no danger of cutting into the old growth because your gut will tell you not to take that much.
Remember that grapes thrive on having ample air flow between the leaves and the fruit, and that as the season progresses, you'll be trimming back the leaves to expose the grapes to sunlight so they can ripen, removing vines now makes more room for that.
My experience of having my vines ravaged by powdery mildew and the devastating amount I ended up cutting back ended up being the best lesson I could've ever learned. And sometimes mother nature is cruel like that just to remind us that while we may try to manipulate the land, it is the land that always wins.
