PITTSBURGH -- Pittsburgh Brewery on Tuesday introduced an aluminum beer bottle designed to keep beverages chilled longer than any other container on the market.

The unbreakable bottles will hold the company’s Iron City premium lager, a beer whose roots go back to the 19th century.

Back in 1962, the Pittsburgh Brewery teamed with Alcoa to bring the world the first flip top can. Within a year the trend caught on and was featured on other beers as well as soda cans.
