From the wonderfully engrish homepage: "Clear bottles make beer unpleasant because of sunlight and the like. So they, Japanese usually use brown-colored bottles to guard beer in Japan. They use green-colored bottles for Heartland Beer and there is no difference in effect. Heartland Beer was originally born in 1986 as beer on the menu of a beer hall, Heartland in Tokyo. The model was a big tree, called Heartland, around Chicago, America. On the beer bottle itself, they have embossed the big tree and it is a little hard to distinguish beer brewed by Kirin Brewery in a look. That unique design parasitically shows how Heartland Beer has been, we can say. Heartland Beer is brewed and produced in Toride city, Ibaraki. Just malt, hops and water are used and they never use extra elements like most kinds of Japanese beer. Heartland beer is out-and-out beer, you know. They have used the decoction method for saccharification; dissolving malt in water and then boiling several separated those. Then the beer smells very sweet and goes down well. We can be proud it is Japanese beer on a level with other foreign beer products."
