Coors Introduces an All-Aluminum Beer Can

In January 1959, Coors introduced a seamless all-aluminum beer can in a Colorado test market after several years of development. Aluminum made the package lighter and resistant to rust, while manufacturing the cans within the brewery demonstrated a new approach to large-scale beverage packaging. The early container still required an opener; easy-open systems developed separately. Coors’s experiment helped establish aluminum as a practical alternative to steel and contributed to its later dominance in beer packaging.
