The appearance of a rather special Tokyo Sky Tree commemorative beer can from Asahi got us frothing at the mouth and thirsty to find out more about this season’s crop of limited edition beers.

Asahi Sky Tree Tower Cans: The miniature Tokyo Sky Tree on the side of this can changes color with a change in temperature. At room temperature it’s blue but once chilled, it darkens to purple. In the run up to the opening of the tower in spring next year, Asahi will be giving away a load of Sky Tree Tower related goods and 50 lucky people who buy one of these six packs of Super Dry or Clear Asahi will win a Sky Tree Tower themed prize. The cans are on sale until Oct 25.

Kirin Ichiban Shibori Toretate Hoppu: Though Asahi’s cans are cool, the product inside is still your standard dry larger, but this one ought to tickle the fancy of beer connoisseurs. Made from hops that have just been harvested in Iwate this beer has a clean finish and a fruity scent. Kirin reopened their Sendai factory, which was damaged in the quake, just in time to get this beer made. The company points out that buying this beer is a way to show your support for the beleaguered farmers in the area. On sale from Nov 9.
