Just in time for the All-Star game, Minnesota's Target Field is the first Major League Baseball stadium to get a self-serve beer station.
According to the Minneapolis Star-Tribune, fans got to try it out on Sunday during the Twins game against the New York Yankees.
The machine dispense four different kinds of beer, and fans are charged by the ounce.
Here's how it works: A customer goes to a concession cashier, shows an ID and buys a $10 or $20 vendor card to scan at the machine. Customers can withdraw up to 48 ounces every 15 minutes, but there will be an employee at each station to checks IDs and step in if someone appears intoxicated.
There's only one station at Target Field at this point, but another is expected to open in time for the All-Star game on July 15.
