How is 90% of all wine coming from California? Is this talking about all wine consumed in America or smth? The other statistics I have not as good an intuition about, but they seem way too high for "all" as in world wide...
Yeah, those numbers are US-centric. It isn't surprising since the post is targeting a US audience.
The numbers seem a bit off, but not by a huge amount. A little Googling suggests that California produces 80-85% of American wine, and about 75% of American fruits and nuts.
