also involved the winemaking and vineyard biz (east coast us). i think that estimate is on the lower end, but also per season (single harvest per year). while the vines do take 5 years to really start producing, they will continue to produce for decades after, with a cyclical nature of peaks and valleys approx every 5 years. $10/per plant seems very low, even if selling only as u-pick. also highly depends on your spacing and grape type. for us in the south east, muscadine grapes are enormous and a single plant with a 12' spread can produce quite a lot per plant at its peak, easily 80lbs of grapes in one season. wine is approx 15-20lbs grapes per gallon from that.
