Because Moutai 1997 is not one of the top ten famous liquors in China. If you look at the trademark and address, it is not produced by the Moutai distillery. It is just one of the many distilleries in Moutai town. Produced by Maotai, which is truly one of the top ten famous liquors, it has no branch factories and no other brands. It is exclusively controlled by the state.
