The actual answer is yes, at least when it comes to wine (although I will note that the trade war stuff is only part of the picture--it has certainly hurt a number of wineries that previously relied on exports, but the wine industry is experiencing a much broader downturn than just this).
Not all wine, of course, but some wine is indeed seeing prices drop. There have been some great deals to be had in the past few years in certain corners, both big and small. Costco has had increasingly good deals on wine lately and other large retailers are having more and more as well.
There's a lot of price stickiness with wine, with wineries not wanting to lower sticker prices (since price is closely tied to branding and market positioning), so there's also been this fascinating trend of wine increasingly being bulked out to online retailers that operate on a rotating flash sale model (companies like Last Bottle or Wine Access), or to third parties who relabel it and sell it under an NDA on the original brand. These segments of the market are only going to continue to grow in the coming years as the glut of wine continues.
Kind of like the Super Bowl and other major sporting events. Normies can make that their "major trip" for the year but mostly they want to sell their multi-thousand dollar tickets to folks who will be at the next big thing the following month.
Prices and costs generally increase as the quantity sold decreases.
If they're buying fewer bottles for example, bottles will cost them more per bottle.
And if they're "losing money on international sales", often times they'll try to recoup that elsewhere. Like jacking up their own prices in justification.
Very likely wine demand was not going up, and price increases were instead due to increasing costs and inflation.
So when demand softens it may be advantageous to hold back the excess rather than lower prices. Yes, there are cash flow issues when this approach gets out of hand, but financial interests can cover a lot of that as well.
Eh, not really true for the cheap end of the market. A lot of wine sold in supermarkets, for example, is meant to be consumed a couple of years after bottling, tops. And storage can be a significant problem.
The real world works much differently.
If you run a competitive business in Capitalist America, you need to keep up with inflation, taxes, and the status quo as well.
You can see it happening in real-time, right this moment. Go to your local Costco wine section, look for the clearance markdowns where the price ends in $0.97. That means it's marked for clearance and won't be coming back, and there's some screaming deals right now.
It's nothing to do with health concerns. It's the economy.
