Oriental Brewery launched Cass in 1994, more than four decades after Doosan Group founded the company. The brand has bounced between global owners more than once — sold off by Anheuser-Busch InBev in 2009, bought back in 2014 — and in 2011 it overtook Hite to become South Korea's best-selling beer, a title it has held ever since.
