Now you might think it's not so bad, there's plenty of other places wine makers can go and get started again. Hell, it looks like a lot of them wouldn't have to move more than a couple county's over to find good atmosphere.
Growing grapes isn't so easy, I've tried. Georgia Red Clay and Malbec doesn't seem produce anything, other than a brown, withering stalk that takes a chainsaw to remove. But we're talking about California, the holy land of new world wine, right? Exactly. But you want to grow grapes, particularly varietals that can be as finicky as wine grapes, which are native to deserts (grapes horde water, like just about anything else in the desert) you're going to set yourself back in time and resources. Vines have to be trained, and they don't produce enough for the first few years to get much out of. Roughly five years in you might be pressing and barreling, but it's only then that you can get a feel for what's going to be in the bottle. Then you have to wait for the damn things to ferment, take on the characteristics of the barrel you put them in, and then, maybe, your taste buds will be able to give you the final picture.
Wine makers have plenty of tricks to speeding up the production of wine, I'm sure, but nobody makes a bottle of wine over night, and when you're talking about moving the whole operation even thirty miles away, it's going to be years before you'll have anything substantial. Sure you can keep the winery in the same place, but vineyards aren't construction sites that can have a dead-line.
So, if the article is to be believed, you should be careful around tall buildings. Wine enthusiasts are going to be throwing themselves off of them.
