Beer firm produces brew with frozen foam head

Japanese brewery Kirin have come up with a solution to the beer-drinkers summer problem of a warm brew -- a drink which is served with a frozen foam head.

Ichiban Shibori Frozen Draft features a frozen foam head which makers claim will act as an insulating lid and keep a drink cold for 30 minutes.

The foam is made by cooling the beer to -5C and then pumping it out Mr Whippy style on top of the glass.
