One thing about Utah, as I lived there for a year many, many years ago, is they have some of the strangest laws. For example:
They don’t call a bar a Bar but a counter top. The taps for draft beer are fake as waiters have to go in the back and pour your drink.
Kegs of beer are also illegal. A lot of people cross the state line and travel to Wyoming to buy Kegs and then smuggle it back. Its illegal, but people do it all the time and the cops make busts all the time too.
You can’t purchase liqueur at a regular store, as all alcohol purchases with a higher proof content are all sold at state run liqueur stores.
Any beer sold at convenience stores is referred to as “nearbeer” as its alcohol content is really weak and one probably has to drink a whole case of it to get a buzz.
Anyway, this law is just dumb, and is the result of Mormon puritanical nonsense.
