We've seen plenty of innovative ways to keep beer cold in recent months, with everything from a refrigerator with a built-in blast chiller
to a can that cools itself at the push of a button
. But these have all involved cooling the beer's container, leaving the liquid inside to warm up at the same rate as any other beverage. That's why Japanese beer maker Kirin has gone a different route, and developed a method for cooling the beer directly and, more importantly, keeping it chilled for much longer. The company's new Ichiban Shibori Frozen Draft stays at a low temperature thanks to a specially-developed machine that dispenses a topping of frozen beer foam like soft serve ice cream.
