Zunyi Flue-Cured Tobacco

Zunyi Flue-Cured Tobacco is a product with geographical indication status.

　　The history of tobacco cultivation in the Zunyi region dates back a long time. Historical records such as *Yin’an Suoyu* indicate that it began in the mid-Ming Dynasty, spanning nearly four hundred years. The tobacco planted at that time was called "leaf tobacco," also known as local or sun-cured tobacco. According to sources such as the *Zunyi Prefecture Annals* and *Zunyi County Annals*, flue-cured tobacco was successfully introduced in Zunyi County in 1940, and later further developed. Tuanxi briefly became a widely renowned market for high-quality tobacco trade. In 1943, flue-cured tobacco was trial-planted in counties such as Zunyi, Meitan, and Yuqing, gradually spreading throughout the region and evolving into an important cash crop for rural areas. Zunyi Flue-Cured Tobacco features good maturity, orange-yellow leaf color, bright luster, minimal color difference between the front and back, excellent oil content, moderate body, loose structure, good elasticity, as well as superior fragrance quality and sufficient aroma, excellent volatility, clean and comfortable aftertaste, strong sweetness, minimal off-flavors, low irritation, and moderate strength. This product boasts mellow and harmonious aroma with noticeable honey-like sweetness, and a soft, lingering profile.

　　During cultivation, biogas residue and biogas slurry are used as ecological tobacco fertilizers. This not only reduces costs but also enhances the intrinsic quality of the tobacco leaves, making it highly favored by tobacco farmers.
