With the MLB All Star Game about to begin, fans will be able to buy their beer at a self-serve beer machines. The idea has been attempted before, but this time around the technology is a lot of better. Here is how it works:

After an ID check — “Just because it’s self-serve doesn’t mean it’s unmonitored,” Twins spokesman Chris Iles said — fans buy a card pre-loaded with $10, $20 or $40. Then they hop in line for their beer of choice: Budweiser and Bud Light for 38 cents an ounce (a little over $6 for a pint), or Goose Island 312 Urban Pale Ale and Shock Top’s Lemon Shandy for 40 cents per ounce. The self-pouring is monitored, too, to stop anyone who may be overserving themselves.

There have been some issues…..

Target Field’s new machines have LCD screens with pouring instructions behind each set of taps, but Spike said they ran into a few hiccups with messy pours on a test run last week, especially after the machines sat idle. The stations will stay at Target Field for the rest of the season, and plans for expansion or changes will depend on fan feedback.

It will be interesting to see the reviews on this machine. Many ballparks are facing actual physical fan attendance issues and this machine would easily replace many beer vendors if it was successful.
