Lotte Liquor

Lotte Liquor (hangul:롯데) is a distiller in South Korea, founded in 1926. It is the world's second leading producer of soju. It also manufactures a variety of other alcoholic beverages including red wine, Kloud beer, and whiskey.
Lotte soju is known by the brand name Chumchurum (hangul: 처음처럼). Chumchurum means "like the first time" (pure) in Korean. The bottles are branded with pictures of a Korean magpie and a bud. In South Korea, the magpie is known as a bird that brings good news, and a new bud symbolizes "new" and "beginning".
Chumchurum contains 19.5% of alcohol and is made with alkali water, which give the soju a distinct taste. The company recommends shaking the bottle well before drinking it, for taste – as in the commercial.
Chumchurum is advertised by Korean famous singer Lee Hyori(이효리). From November 2012 the liquor is advertised by Hyuna, Hara & Hyorin. BLACKPINK's Jennie has become the new model for Chumchurum starting January 2021 and is expected to hold that title for 4 years.
The company's current president is Jae Hyeok Lee.
