Oolong Milk Tea
Oolong milk tea is a milk tea, often a bubble tea, built on a brewed oolong base instead of black tea: the oolong's roasted or floral character gives a more aromatic, less tannic milk tea than a classic black-tea version. It is a staple of the boba and milk-tea world, served hot or iced, sweetened, and frequently with tapioca pearls. Note that this is a prepared drink, not to be confused with milk oolong (the jin xuan cultivar), which is a plain tea that tastes creamy on its own.
A real oolong base brewed strong enough to carry the milk: roasted oolong gives a toasty, caramel note, while floral high-mountain oolong gives a lighter, fragrant one. Shop versions range from freshly brewed leaf to powder mixes, and the freshly brewed ones taste far better. Watch the sugar level, which is often very high by default. The pearls (tapioca) are a texture add-on, not part of the tea itself.
A product of the Taiwanese milk-tea and bubble-tea tradition that spread worldwide, oolong milk tea uses the island's signature tea type as the base, and the roasted-oolong version is especially popular for its toasty depth. Because it is a prepared drink, the variables are the oolong base, the milk or creamer, the sweetener, and any add-ins, and quality tracks whether real brewed tea or a flavored powder is used. It is distinct from jin xuan milk oolong, a cultivar whose leaf tastes creamy unbrewed.
Brew a strong oolong base: roughly 6-8 g per 200 ml of 90-95°C water, or a concentrated gongfu brew, so it stands up to milk. Sweeten to taste, add milk or a milk alternative, and serve hot or over ice; add cooked tapioca pearls for bubble tea. A roasted oolong base suits this best, while a fragrant high-mountain base gives a lighter version.
As a shop drink it is priced per cup, not per 100 g. Made at home, the cost is the oolong used (see Dong Ding or Ali Shan for leaf ranges) plus milk and any pearls, and a real roasted or high-mountain base elevates it well beyond a powder mix.

Oolong milk tea is frequently confused with milk oolong, but they are unrelated: milk oolong (jin xuan) is a tea cultivar with a naturally milky aroma that is brewed plain (though much of what is sold as milk oolong is additionally scented with milk flavoring), while oolong milk tea is a prepared drink that actually contains milk. The roasted-oolong version is prized in bubble-tea shops for the toasty depth the roast adds.
