The reason for this relationship is because of the relationship between religiosity and policy:
Local regulations determine the level of production much more than demographic characteristics such as income or education, says Bart Watson, chief economist of the Brewers Association, a craft-beer trade organisation. And religious legislators may get a bit overzealous. Utah, a state populated with many teetotaling Mormons, strictly limits the strength of draught beers and cocktails. Bartenders in the state must also mix drinks behind large barriers called “Zion curtains” (for the sake of the children, of course). No surprise then that it appears not to have caught on to the craft-brewing craze.
