HGT華剛茶業 (Hwa Gung Tea Company)

HGT Hwa Gung Tea Company traces its tea-growing roots to 1918 and is now run by a fifth generation of the same family, working from the Huagang processing factory at roughly 2,500 meters in the Lishan high-mountain tea region - one of the highest-altitude oolong-growing areas in Taiwan, where the elevation and temperature swing are what give the leaf its character. The company processes its own harvests on site rather than buying leaf from brokers, pairing generations of hands-on experience with a more scientific approach to orchard management and a traceability system that tracks tea from cultivation through production, grading and quality assurance. That combination helped it become the Michelin Guide's first global high-mountain tea partner, a recognition built around the company's stated goal of becoming a leading producer of oolong specifically, rather than a general tea house. The house philosophy, translated roughly as human-centered and tea-rooted, points to a business that still treats the processing factory and the family running it as the core of the operation, with the Michelin partnership functioning as outside validation of a method the family had already been refining for five generations rather than a marketing pivot. For high-mountain oolong drinkers, the elevation number alone - 2,500 meters - puts the leaf in company with some of the most prized growing sites in Taiwan.
