As competition in the beer cooler gets tougher, breweries big and small are making changes to package design to catch more eyes. Already this year, beer titans Budweiser, Miller, Heineken, and Sam Adams have all announced major makeovers of their can and bottle looks. 

In South America, Brazilian beer brand Antarctica made a big change to its packaging just in time for this year's annual Carnivale by adding a scannable subway ticket directly onto its can's label. To support the program it worked with the city of Rio de Janeiro and installed "beer turnstiles" at major train stations that scan and collect cans for recycling in one simple motion. Riders simply save their last empty or find a discarded can for a free ride home. The campaign is a social initiative as well, intended to cut down on litter and drunk drivers. [via Adverblog]
