The Oolong No. 17 hybrid, also called Ruan Zhi Oolong, a queen among the teas of north Thailand, is originally a product of the Taiwanese Oolong Tea Research Program. The tea cultivar, worldwide successful and highly valued due to its dominating fine sweetness, its quality consistence over the year’s harvesting cyle (compare Four Seasons Ooolong Tea), its relative altitude indifference and pest-resistance, has been imported from Taiwans Alishan mountains to north Thailand since the early 1990s in the context of a Thai Royal Development Project initiative with the goal of substituting the illegal opium poppy cultivation in north Thailand with suitable and promising legal cash crops. The main region in north Thailand for the cultivation of the Ruan Zhi Oolong No. 17 cultivar is Doi Mae Salong, where thanks to the impetus of the Thai Royal Development Project, which has dedicated its agricultural programs to the orientation on the principles of organic crop cultivation, and the millenium-old inheriteted knowledge of Doi Mae Salong’s ethnic Chinese population, the plant finds optimal climate and geological conditions similar to those in its place of origin at altitudes between 1200 and 1800 meters and a seasonal change between a rainy, a hot and dry, and a cool period in a 4-months rhythm, and has since been brought to a new level of perfection by the local population of ethnic Chinese (Yunnan) origin.
In the nomenclature of DMS Ruan Zhi Oolong No. 17, DMS stands for the region of cultivation, Doi Mae Salong, No. 17 for the tea plant cultivar also named Ruan Zhi, Jade for the color of this only lightly fermented tea’s liquor and its precious character, and Pearls for the rolled form to which this tea is usually processed.
The beautiful, carefully handpicked, rolled leaf will – infused in hot water – open to its full size within less than a minute and produce a clear jade-green to bright yellow cup, mild, yet rich in aroma, with a velvet-fruity touch of sweetness and a charming flowery note to its taste.
DMS Ruan Zhi Oolong No. 17 Jade Pearls unfolds the depht and diversity of its rich spectrum of fine, subtle taste nuances best with a dosage of 3 – 5 grams of the tea pearls on 250ml hot water, at a water temperature around 85°C and a recommended infusion period of 1 – 3 minutes. The tea maintains its taste for 3-4 or even more infusions, each of which will exhibit its very own character.
Just like other high-grade Oolong teas in its class, this Jade Oolong Tea, Ruan Zhi Oolong No. 17, is also perfectly suitable for the traditional Chinese form of tea preparation, the ‘Gong Fu Cha’ or ‘Tea Ceremony’. In order to appreciate this tea’s individual taste and aroma nuances in even more detail, tea masters will infuse the DMS Ruan Zhi Oolong No. 17 Jade Pearls up to 7 times or more with this special and particularly sophisticated form of tea preparation.
