Ethanol is naturally occurring.
That said, I agree that including alcohol here is bizarre. As far as I can tell there has never been a monotonic increase in ABV; instead, there is a large selection ranging from high alcohol content to even alcohol-free (which is so unpopular in the US as to be barely worth mentioning, but quite popular in Germany, and I'm now seeing large and even regional breweries in the US produce AF versions of their most popular beers).
> Unless they're talking about distillation
Most alcoholic beverages are made through some sort of distillation process, so I'm not sure what difference you're alluding to here.
