For the wine producer what happens is that as their product becomes more and more expensive for Americans, their ability to make sales decreases (as American clients stop buying some wines because they become too expensive), the winemaker's profitability decreases, and in turn perhaps they have to lay some employees off (or make other tough business decisions) because they can't make payroll or pay certain suppliers or whatever.
Those results are obviously probably a little further away than the visit of someone who is coming in a few weeks, but the likelihood is that these types of consequences will hit at least some producers in the next few months / years.
