Safflower lang and Qinghualang are both products of Langjiu Group, but there are significant differences in brewing technology and positioning. Qinghualang adopts the "987" process, and the whole production cycle is as long as one year, and it is stored in Tianbao Cave. This technology pays attention to the fine control of time and technology to ensure the quality and taste of wine. In safflower lang, however, the production cycle is relatively short, different techniques are adopted and stored in a treasure cave. This process may pay more attention to efficiency and output.
