Hannah, Ram; The renaissance of canned beer is in full effect, led by the microbrewing community. Mny of the brewers out here are focused on sustainability, which aluminum makes easier. also, the cans keep light from skunking the beer, giving longer shelf life.
Plus, based on my Southern/borderline redneck roots, there's just something about reaching into an icewater filled cooler and pulling out a near-freezing can of beer and knocking it back. Look for Dales, Caldera, 21st Amendment, New Belgium, Ft. George, and Hopworks as great examples of quality canned beer.
