The US is quite a large land mass and thus has the ability to produce almost every kind of alcohol you can think of. Some areas are better for growing grains, and others are better for growing grapes, etc. As someone who enjoys mixology as a hobby, I’d say my shelf is about 70% US made liquors and the rest are imported. Most of the wine I’ve come across has been made in California. And ever since craft brewing had a moment, all the beer me and my friends drink are US made as well and those can get pretty hefty if you drink things like stouts. I usually just assume that every country has found a way to make at least one type of high proof product out of “necessity” at one point in time.
On the one hand, we already do it to cigarettes so it makes sense to do it to alcohol as well. On the other hand, why aren’t we labeling other items that have a cancer risk like floss or nonstick pans or a plethora of other items? Sometimes I see the little state of California warning sticker, but I know loads more stuff should be labeled that aren’t.
