Mộc Châu oolong · Highland green tea

Mộc Châu is a plateau in Sơn La province in the Northwest, spreading above 1,000 metres with lush grasslands and a cool climate year-round. Sitting on National Highway 6 linking Hà Nội to the Northwest, Mộc Châu is at once a tea basket, a dairy land, and a renowned tourist destination.
Tea-making here began under French rule with the first plantations, later growing into large-scale state tea farms. From the 2000s, oolong cultivars and modern processing techniques were introduced, opening a premium tea line for the region.
The soil is red basalt and ferralite over limestone — a deep, well-drained tilth; the misty plateau, sunny by day and cold by night, gives the buds body and lets them gather fragrance. These are ideal conditions for high-grade oolong and green tea.
Mộc Châu oolong passes through withering, tumbling for fragrance, and rolling into tight round pellets; in water each pellet slowly unfurls, yielding a golden liquor, orchid and ripe-fruit aromas woven with a buttery richness and a long sweet finish. Alongside stretch the rolling green tea hills that have become a tourism icon.
The land is home to the Thái, Hmong, and Dao peoples together with farm-worker communities; tea culture blends with grassland culture, and the tea-picking festivals and seasons of white plum and canola blossom draw visitors from afar.
Thanks to Highway 6 and a reasonable distance from Hà Nội (about 180km), Mộc Châu ties tea production to experiential tourism: visitors can pick tea, watch processing, and taste on the hillside. This 'tea plus tourism' model lifts the value of the produce and builds a lasting livelihood for the locality.
Oolong is harvested in several flushes, best in the cooler months; the tea belt centres on the Mộc Châu State Farm town and hamlets across the plateau, home to the famous heart-shaped and S-curve tea hills.
Genuine oolong forms tight round pellets that open evenly in water, giving orchid and ripe-fruit aromas and a long sweet finish; choose by season from a reputable maker. Brew at 90–95°C for 5–7 infusions, and pair a visit with hands-on tea picking.
