Look at what you're replying to.
As already stated, this is the ESTIMATED RETAIL VALUE of the wine, NOT the Sales Revenue.
You then conflate this with the EXPORT VALUE of Californian wine, which is not the retail value but the price the winery is selling the wine for to a foreign buyer.
Apart from that the value also doesn't matter, in the context of AMOUNT of grapes purchased the QUANTITY of wine produced is more relevant than the VALUE created with it.
> "You literally have this situation. Only 2% of California wine goes to the export market at all, and people are literally arguing that [..]"
Again, it's not 2%. You literally need to read the sources you cited yourself. They provide good data to educate yourself and see where you're trying to force a conclusion without the proper facts.
And nobody is "arguing" what you state. The OP stated "It's a shrinking market, but it surely doesn't help that people are simply boycotting US goods." and you're trying to ridicule him for that without having any leg to stand on...
