I’ve been coming to the understanding that “bourbon” is like champagne in that it doesn’t describe a type of alcohol so much as alcohol of that type produced in a specific region (though with the caveat that there might be factors about that region that also means boubon is a distinct type of alcohol due to those factors). If that’s accurate, wouldn’t it mean that “the American bourbon industry” is redundant like “the French champagne industry” would be? All Bourbon is American.
