The state of Utah as a whole seems to have the lion's share of weird laws. When the Mormons moved into the territory in the late 19th century, they carried with them a deeply rooted religious faith that has undoubtedly helped to mold many of the laws that were initially passed. Many of them are still on the books to this day.
When it comes to alcohol, Mormons not only abstain from consumption, they had their state legislature make it harder for others to imbibe. The state of Utah forbids beverages to be sold that contain more than 3.2% alcohol (via Stupid Laws). Possession of beer is okay in this state, provided that the container has less than 2 liters of the beverage within it. If you're a retailer, you are excluded from this law.
Should the governor of Utah declare an emergency, then all alcohol sales must cease. This state law prohibits not only the sale of alcohol during such a time, but also makes it illegal to "otherwise furnish" alcohol to another person. Just in case you were considering a creative trade, you might want to hold off.
Enjoying wine with your meal at a restaurant in Utah is perfectly fine. But you have to ask for a wine list before being offered a glass.
