Here are the current laws for tavern owners, issued by the Wisconsin Department of Revenue

Class "B" (beer), "Class B" (intoxicating liquor including wine), and "Class C" (wine only) licensed premises must be closed from 2 a.m. until 6 a.m. Monday through Friday. On Saturday morning (following Friday night) and Sunday morning (following Saturday night), you may stay open until 2:30 a.m. On January 1 (following New Year's Eve), you do not have to close.

Certain businesses, like hotels, restaurants whose principal business is selling food, bowling centers, indoor horseshoe-pitching facilities, curling clubs, golf courses and golf clubhouses, may stay open after these hours for their regular business but may not sell or allow consumption of beer, wine, or liquor.

So, I guess the bars have to close overnight, but they can open at 6 AM to handle the night shift from the factories - not that there are many factories left in Wisconsin.

One other unusual thing about Wisconsin drinking law:

Under current law, minors of any age are allowed to consume alcohol in a licensed tavern, restaurant or other licensed premise if they're accompanied by a parent, guardian or spouse who has reached the legal drinking age of 21.
