A Pennsylvania brewery is betting beer drinkers are willing to pay an extra dollar to keep their drinks cold nearly an hour longer. Pittsburgh Brewing Company -- maker of Iron City Beer -- plans to sell beer in aluminum bottles. It's teaming up with Alcoa, the world's largest aluminum maker, to produce the bottles, which are said to have superior insulation. About 20-thousand cases of the new aluminum bottle beer are en route to as many as 28 states and should be on shelves this week. The bottles have three times the aluminum of a typical beer can. It's not the first time Alcoa has teamed up with the local brewery to put out a new product. In 1962, the two put the first pull-tab beer cans on shelves.
