No winery yet. I only planted 240 vines the first year (2019) and those vines had a small crop this past year that was harvested by the racoons. If I ever get a decent crop, we'll see whether I sell grapes or start a small winery. One and a half acres is not a large vineyard so I'm aiming for at least 3 or 4 acres. Once I get the vines producing, I can't expect much more than two tons an acre. A ton of grapes will yields about two barrels or 120 gallons so 3 acres would only yield 300 to 400 cases. Even the smallest wineries produce about 800 to 1000 cases a year. We are still learning and trying to get established. I do love every minute spent in the vineyard (save the discovery of the racoon harvest and the Great Mother's Day freeze).
I considered TWC but I have different varieties throughout the vineyard, some will do better on TWC and others on VSP. I'm going with VSP for ease of netting, spraying with a tractor mounted sprayer and ease of harvest. I'm not keen on reaching overhead to harvest. I'm trying to plan netting and have decided that fruit zone netting will be the best. Overhead netting will be a problem with mowing; my husband does the mowing and he will get tangled in the netting (I've spent many hours under mowers unwinding wire, string, hoses...).
I don't think tucking vines will be tremendously labor intensive. I'm walking along the rows constantly and assessing the vines, checking for disease, bugs, damage, pulling leaves, cluster thinning, spraying weeds, tying vines, so tucking vines is just another action. I can always change to TWC or mid wire if I chose. Just run a cane to the higher wire.
One other (sort of secret) reason for VSP is what the public expects a vineyard to look like. A huge business for wineries and vineyards is as a wedding venue. That is why I'm using wooden trellis posts. Metal posts would be so much easier to install and would last longer but don't look pretty in a picture.
