Thai Oolong (Jin Xuan)

ชาอู่หลงจินเซวียน

Lightly oxidized rolled oolong, from Chiang Rai, Thailand.

Oolong tea

Thai Oolong (Jin Xuan) is strongest on smoothness, creamy and sweetness. Typical tasting words: milk, butter, vanilla, orchid, sweet pea. Cultivated in northern Thailand since the late twentieth century after Taiwanese tea cultivars were introduced as part of crop-replacement initiatives for opium poppies. A cornerstone of tea tourism in Mae Salong, popular with domestic consumers and international visitors alike.

Also known as Thai Milk Oolong, Doi Mae Salong Oolong and Jin Xuan No. 12.

Caffeine

A cup of Thai Oolong (Jin Xuan) carries a typical estimate of 40 mg of caffeine, within a range of 25 to 55 mg depending on leaf amount, water temperature and steeping time. Figures are estimates for a 240 ml cup. Better earlier in the day if you are sensitive to caffeine. The caffeine planner turns this into a daily total.
