Virginia is big on agritourism and MANY people that visit a winery in Virginia ask (first question I ask), what are you growing/which wines are estate wines. The reason most of us are looking at farm wineries is because prior to 2019, the farm winery was the only way to have a tasting room and as Fred pointed out, the zoning requirements are much less.
On the other hand, you may have trouble buying quality fruit. Of course you can just truck in juice or fruit and make non-Virginia wine.
Personally, I'm into growing and showing off what I can grow in my area. The winery will be more than just a production area, bar and retail area. Our winery will showcase our wine, our vineyard and our gorgeous area of Virginia.
