OB Lager is a brand born in 1952, known as one of original beers in Korea. (The name “OB” stands for “Oriental Brewery”) It was loved by Koreans for a long time, but as millennials came of age, consumers started to find this brand old. No one looked for this brand and it was almost invisible in the market. (From 2015(oldest trackable year) to 2019, the sales volume decreased by 90%)
