You can find proper wine at 4-5€ at the producer, 3.5€ is probably the strict absolute minimum where you can find honest wine direct from producer. Any thing below is just fermented garbage, the grappes that otherwise would spoil the wine, it just happen to have sugar to be fermented, I don't know how the hell how they are pre-processed, just stay away from it.
And I could buy British gin in Hong Kong cheaper than in UK

"The natural advantages which one country has over another, in producing particular commodities, are sometimes so great, that it is acknowledged by all the world to be in vain to struggle with them. By means of glasses, hot-beds, and hot-walls, very good grapes can be raised in Scotland, and very good wine, too, can be made of them, at about thirty times the expense for which at least equally good can be brought from foreign countries."

For wines in a top US region, you wind up paying a ton of money for the mortgage on the land, too.

German wine in the USA is just mass market Rieslings and maybe an ice wine and nothing else. We’d always joke that they save the good stuff for themselves.
Similar to how a pack of cigarettes costs $15 in NYC and $6 in Raleigh, NC.

Even in Raleigh, there are taxes on tobacco.
Eventually, more often than not the temperature control and matching wine with what you eat matters more than anything.
If what you’re saying is true, then an acre in the Napa valley is more than twice as expensive as its counterpart in the Champagne region. Which is weird, I’d expect the Champagne acre to still make you a lot more money
(Making good recommendations may well be more profitable than making bad recommendations, because if they make bad recommendations you'll stop coming back. But they absolutely are trying to sell you something).
Works out to about $20 a bottle in California.
