Also, the idea that California wine - of all products - is very sensitive to exports is a bit strange since although California wine sales account for more revenue than the entire wine industry of any other country -- 68 billion dollars worth of sales each year (https://wineinstitute.org/our-industry/statistics/california...), the state exports relatively little, only about a billion dollars of California wine is sold abroad. So 98% of California wine is sold within the US. Only 2% is exported.
And yet there are so many people on this board that are convinced that Europe, of all places, is somehow responsible for driving California wine grower sales woes.
It's pretty funny if you think about it, you have some Bosnian dude and when you tell him that Ford is facing a sales slump he immediately shoots back -- it's because the Bosnians are no longer buying Fords! Truly an amazing example of economic narcissism.
