check this out AMAZING AUTOMATIC BEER POURING MACHINE

Now - let’s think about it. 

This is very cool from my perspective.  I love thinking how some engineer figured this out.  In a society where beer  is not taboo, this is in the Tokyo Internation Airport.

My only concern is the last step - the pour seemed like it was going well anyway, why the switch to the foam only shot at the end?  One of the benefits of naturally occuring foam is the delivery of aroma.  Can’t see how this gets aroma to us.  The other thing to think about is: is there more than one beer in the machine and if so, how can we tell if the foam is coming from the same beer. 

Ah - always the cynic.

Cheers
