This.
You have your pet theory, you, without evidence, decide that every fact you see is confirmation for that theory, so now you believe your theory even more.
I want to say something to make you feel bad about this, but you think I'm telling you that you were right all along.
As usual the reason overall wine sales would be down e.g. 10% and US wine sales down 20% in a country will be a combination of multiple factors. My pet theory though is that at least for some countries, the boycott factor is the big one.
> "In 2025 the U.S. wine exports plummeted 33.5 percent compared to 2024, driven largely by a 76.8 percent drop to its largest market, Canada, according to new data just released by the U.S. Census Bureau. In total, American wine exports fell from $1.3 billion in 2024 to $850 million this past year, a $428 million loss." [1]
So the largest export market dropped by 3/4 which led the total exports to fall by 1/3. I don't know how that is anything but a "real consequence"?

Lets use your numbers then.
Total US domestic sales were about 3.3 billion liters.
Exports were about 253 million liters.
Exports, if they went to 0, would explain less than 8% reduction in wine sales.
But the article quotes a 20% drop.
Exports have decreased maybe 1/3 and that is only in the last 2 years, and that is by your own numbers. That would constitute a 1.5% drop, not a 20% drop.
So changes in exports do not have a significant effect on the numbers, and cannot explain a 20% drop, or even a significant portion of a 20% drop.
Thank you for confirming my point though.
Do you really go through life seeing confirmation of all your beliefs everywhere, without ever checking?
US consumers spend about $115 Billion annually on wine. Exports to canada are less than 1% of that. I don't see how Canada matters much to the US in general, and specifically it doesn't make sense that a 70% reduction in half a percent of wine sales (that's like 0.4% reduction overall) is a major factor in putting the industry out of business, but you are welcome to look it up yourself or correct me. Keep in mind that US wine sold in canada will have gone through several hands and be heavily taxed, so the amount per bottle getting back to grape growers is a very small percentage of that already tiny percentage.
But of course you won't bother to look it up, you will just roll your eyes and assume US grape growers are being forced out of business because Manitoba's liquor stores are finally flexing their international influence!
