If there is a more distasteful thing than lukewarm beer, we don’t know what it would be. Japanese beer company Kirin gets it, so they’ve invented a frozen beer foam to keep your brew chilled. It looks kind of like a swirl of soft serve ice cream plopped into the top of a pint of beer, but it’s actually extremely cold beer that’s had air blown into it.

Ichiban Shibori Frozen Draft was recently introduced into restaurants in Tokyo. The foam is supposed to keep the beer super-cold (-5 degrees Celcius) for 30 minutes, which gives imbibers plenty of time to down the brew before it takes on that icky lukewarm quality.

The demonstration video gives a good idea of how cool the foam looks coming out of the machine, but doesn’t really give any helpful information. We’re anxious to know if the foam is as easy to slurp up as regular foam, whether it changes the drinkability of the beer and whether the company will ever make our dreams come true by offering soft-serve beer foam sundaes.
