Milk Oolong: What It Is (and Why There Is No Milk)

Milk oolong (nai xiang wulong, 奶香乌龙 - "milk-fragrance oolong") is a lightly oxidised oolong made from the Jin Xuan cultivar, and no milk touches the leaf at any stage. It is not the bubble-tea drink: oolong milk tea is tea with milk poured in, while milk oolong is pure leaf that smells of cream on its own.

Why does it taste creamy without milk?

The creaminess is grown, not added. Jin Xuan leaf naturally carries aroma compounds that our noses read as butter and warm cream, and light oxidation with a gentle rolling into tight green pearls keeps them locked in the dry leaf.

You may hear that the tea is "steamed over milk", or that the bushes are watered with it. That story is a myth: no producer does this, and no step of oolong processing involves dairy. The real cup gives sweet cream, orchid and warm pastry, with a velvety body and a long, mellow finish.

From Taiwan No. 12 to our cups in Phuket

Jin Xuan (金萱) was bred at Taiwan's Tea Research and Extension Station and released in 1981 as Taiwan No. 12; breeder Wu Zhenduo named it after his grandmother. The bush proved hardy and generous. Within a decade it had crossed the strait into mainland gardens.

Ours is mainland-grown Jin Xuan from Yunnan and Fujian - the same regions our other oolongs come from. Come by the tea house at 101 Cherng Talay Road and smell the dry leaf before you buy: real Jin Xuan smells of cream before water ever touches it. Among the types of oolong, its light oxidation and ball-rolled leaf place it beside Taiwanese high-mountain styles, far from the roasted Wuyi teas.

Natural creaminess or added flavouring - how do you tell?

Much of the cheap "milk oolong" on the market is ordinary leaf sprayed with milk flavouring. The spray smells louder - condensed milk, almost dessert - and it collapses after the first steep, leaving flat leaf behind.

Genuine cultivar creaminess is quieter, and it lasts. When we taste lots for our milk oolong, we brew every candidate gongfu style: if the cream note holds through four to six steeps, softening into orchid and pastry, the lot passes. If steep two tastes like plain green oolong, it was perfume.

How to brew milk oolong

Water at 85 °C, about 3 g per 100 ml, 3–4 minutes in a Western-style pot. Boiling water scalds the aroma - the cream note is the first thing to burn off. Gongfu brewing suits it even better: a small pot and quick pours, and the leaf holds 4–6 infusions, each one rounder than the last.
