Introduced to the beverage market in 2001, the aluminum bottle sought to combine the traditional, beloved feel of a bottle, with the durability and recyclability of aluminum. They also have the benefit of blocking out sunlight, which can skunk a beer with the quickness. Anheuser-Busch became the first major brewer to package beer in the bottlecan (as it is sometimes called). You're most likely to see them at sporting events these days.
