Stone City – 3:15 Company History
In 1991, Stone City Industrial Co., Ltd. was established. The factory has earned international FSSC 22000 certification and MUI Halal certification. Its quality is further safeguarded by national oversight – through the Ministry of Agriculture and Food Industries’ “Factory-Field Cooperation” program, we implemented tea garden health management. A tea improvement factory conducted pesticide and heavy‑metal residue testing; not only did we pass safety inspections, but we also received support from the Ministry of Economic Affairs’ Commercial Service R&D Guidance and the Executive Yuan’s Agricultural Committee’s overseas product image improvement and design guidance, earning an outstanding reputation for quality and trust.
Mr. Zhu Junhong, founder of Stone City Industrial, comes from a tea‑farming family and loves Taiwanese tea. With a century of family tea‑making experience, he founded the 3:15 Biotech Center in 2008 to replicate ancient tea‑tree wild‑tea experiments and recreate teas favored by successive emperors. We selected the pristine red‑silver soil area in Mingjianpu, Nantou County, which is rich in minerals and ideal for cultivating tree‑shaped tea trees, promoting deep‑root absorption of minerals and trace elements. In 2016, we officially launched Taiwan’s sole “Natural Breeding R&D Base” project for wild tea and coffee plantations. The coffee species currently planted include Peca‑mara and Mandheling.
The 3:15 products sell worldwide, reaching more than 35 countries including the United States, Canada, mainland China, Hong Kong, Japan, Singapore, New Zealand, Malaysia, Australia, and Europe, and have won widespread support and affection from global customers!

**Traditional Tea‑Making Experience**
Sunlight withering → indoor withering → rolling → killing → rolling → twining → final product
With a century of tea‑making tradition, we insist on following ancient techniques. The full‑sensory (sight, sound, touch, smell, taste) experience lets customers feel how an old tea master works. No step is rushed; fresh tea leaves undergo sunlight withering, indoor withering, rolling, twining, drying, and more to reproduce the original ancient flavor. This is not just a taste of ancient methods; it also teaches tea varieties, properties, and how processing affects tea benefits, giving a complete tea‑culture experience.
