You can understand the confusion that the Washington Post wonders about.
The beer, from Utah, called Polygamy Porter is available for sale in Idaho, in stores generally that sell beer.
But Idaho liquor stores, you can't buy another Utah alcohol product called Five Wives Vodka, made in Ogden. They sell it in Utah (which Polygamy Porter isn't), but not in Idaho. The Post quoted Idaho State Liquor Division administrator Jeff Anderson as suggesting it was offensive: “The bottom line is, we represent everybody. It’s masterful marketing on their part. But it doesn’t play here.”
We can think of some quarters, at least, where it would play just fine.
