ABOUT
Cao Bồ is one of the well-known ancient tea tree areas of Hà Giang province in northern Vietnam, respected for remote mountain forests where old Assamica tea trees continue to grow in natural high-altitude environments. Teas from this region are appreciated among experienced tea lovers for their strong mountain character, mineral complexity, energetic structure, and excellent long-term ageing potential. Compared to younger ancient tree teas, well-aged Cao Bồ material develops greater depth, smoother integration, and a more mature aromatic profile while preserving freshness and vitality.
This 2014 Cao Bồ Gu Shu Mao Cha was produced from spring-harvested leaves collected from ancient tea trees and processed according to traditional sun-dried mao cha methods. After harvesting, the leaves underwent withering, wok-firing, rolling, and natural sun-drying before being stored and naturally aged in Vietnam for more than a decade. Vietnamese storage conditions, shaped by stable humidity and warmer climate, gradually softened the sharper edges of the young tea while supporting the development of deeper woody-mineral tones, integrated aromatics, and a smoother overall structure.
As loose mao cha, the tea remains in its uncompressed form, allowing both the mountain terroir and the long-term ageing process to express themselves with clarity and transparency. Over years of natural maturation, the infusion has developed complex notes of aged wood, medicinal herbs, dried fruits, minerals, and cooling herbal freshness while maintaining the energetic character of ancient tree material. These qualities make aged Cao Bồ mao cha especially attractive for tea practitioners seeking mature northern Vietnamese ancient tree teas with developed ageing complexity and strong mountain identity.
TERROIR
Cao Bồ is located within the mountainous Hà Giang province of northern Vietnam, an area characterized by high elevations, dense forests, frequent mountain mist, abundant rainfall, and rich biodiversity. Ancient tea trees in this region often grow at altitudes ranging from 1200 to over 2000 meters above sea level, where cool temperatures and significant day and night temperature variation support slow and balanced leaf development. These environmental conditions contribute to the freshness, mineral structure, aromatic clarity, and strong ageing potential characteristic of Cao Bồ ancient tree teas.
The tea trees growing in this area are primarily ancient Assamica varietals naturally integrated into mountain forest ecosystems rather than cultivated plantation environments. Deep root systems allow the trees to absorb minerals and nutrients from rocky mountain soils, while the surrounding forest vegetation creates stable ecological conditions and highly complex aromatic development. The interaction between altitude, humidity, forest biodiversity, and mineral-rich terrain contributes to teas with floral-herbal freshness, woody-mineral depth, cooling sensations, and long-lasting returning sweetness.
Compared to many traditional Yunnan raw Pu'Er teas, the terroir of Cao Bồ often produces a bright and energetic mountain profile with expressive freshness and pronounced mineral character. At the same time, the teas maintain depth, structure, and strong maturation potential characteristic of high-quality ancient tree material. After long-term Vietnamese storage, the strong mountain freshness gradually transforms into deeper woody-mineral complexity while preserving the tea’s clarity, cooling sensations, and energetic character.
ORGANOLEPTICS
The dry leaf appearance is mature and deeply expressive, with large twisted leaves and visible buds showing dark olive, brown, and muted silver tones developed through more than a decade of natural ageing. The aroma of the dry leaves is rich and layered, combining notes of aged wood, dried fruits, medicinal herbs, forest honey, minerals, and subtle resinous undertones. In a preheated teapot, the tea gradually opens up, the aroma becoming warmer and more integrated, revealing notes of tree bark, camphor, autumn leaves, dried flowers, old books, and soft earthy-mineral depth. After a brief rinse, the leaves fully awaken, and the aroma becomes smoother and more complex, combining mature woody-mineral tones with herbal sweetness, cooling freshness, dried fruits, and delicate medicinal nuances. The aroma of the liquor in the empty cup is warm and highly persistent, showing aged wood, minerals, medicinal herbs, resin, dried fruits, and soft honey sweetness with remarkable depth and aromatic clarity.
The taste is smooth, dense, and deeply structured, with a thick and rounded texture developed through long-term Vietnamese storage and natural ageing. From the first infusions, mature sweetness and woody-herbal notes emerge, gradually transitioning into deeper mineral, medicinal, resinous, and lightly earthy tones characteristic of long-aged ancient tree mao cha. The bitterness is highly integrated and refined, supporting the structure without sharpness, while the mouthfeel remains thick, calming, and deeply grounding throughout multiple infusions. The aftertaste is exceptionally long, cooling, and persistent, with returning sweetness, strong salivation, and lingering mineral freshness gradually developing throughout the mouth and throat. In the empty cup after drinking, warm notes of aged wood, dried fruits, medicinal herbs, minerals, resin, and delicate honey sweetness remain with a deep and lasting aromatic finish.
