Japanese beer company Kirin has unveiled a new beer with frozen foam in the restaurants of Tokyo this month. The variant, called “Ichiban Shibori Frozen Draft,” features cold Kirin beer topped with frozen beer foam created using a process called Frozen Agitation, wherein air is blown into the beer as it is stirred and chilled.

The foam is very cold at -5 degrees celcius, which, according to Kirin, can help keep the beer below it ice-cold for roughly thirty minutes. Watch a preview of the Ichiban Shibori Frozen draft in the video below:

Ichiban Shibori Frozen Draft is available in Tokyo for a trial run and will be launched throughout Japan by May.
