Milk Oolong Hot (Jin Xuan Gongfu & Western Brew)

By • Updated October 2026
Jump to Recipe ↓

Milk oolong (Jin Xuan) is one of Taiwan's most beguilingly creamy teas—and it gets that buttery, almost-milky flavour entirely naturally. Despite the name, no dairy is involved; the lactone compounds that form during oxidation give this oolong its signature silky texture and sweet orchid aroma. Brewed hot, it unfurls into a golden liquor with notes of fresh cream, honeysuckle and warm butter.

You can steep milk oolong two ways: gongfu in a porcelain gaiwan for layered, evolving infusions, or Western-style in a teapot for a single, longer brew. The gaiwan method—multiple short steeps with the same leaves—lets you taste how the flavour deepens from floral sweetness to richer, toasted notes across five or six rounds. Either way, use water just off the boil and pay attention to timing; milk oolong's moderate oxidation (around 20–30%) means it's forgiving but rewards precision.

Instructions

1
Warm: Rinse your porcelain gaiwan (or teapot) with a splash of just-boiled water, swirl and discard. This preheats the vessel and helps maintain a stable temperature during the steep.
2
Add Leaves: Place 5 g milk oolong in the gaiwan (about 1 heaped tablespoon of rolled leaves). The leaves will look tightly furled; they'll open dramatically once wet.
3
Rinse (Optional): Pour a small amount of 90–95 °C water over the leaves, let sit for 5 seconds, then pour away through the lid. This 'awakens' the leaves and releases dust. (Skip this step if you prefer, especially for high-quality high-mountain oolong.)
4
Steep (Gongfu): Pour 200 ml water at 90–95 °C into the gaiwan, cover with the lid, and steep for 30–45 seconds for the first infusion. Tilt the lid slightly and pour into a fairness pitcher or cup, using the lid to hold back the leaves. Taste the liquor—it should be sweet, creamy and lightly floral.
5
Re-steep: Re-use the same leaves for 4–6 more infusions, adding 10–15 seconds to each steep. The flavour will shift from delicate orchid to buttery sweetness, then toasted grain in later rounds. This is the beauty of gongfu brewing.
6
Western Method: Alternatively, use a teapot: add 5 g leaves, pour 250 ml water at 90–95 °C, steep covered for 2–3 minutes, strain and serve. You'll get one long, full-bodied cup with balanced creaminess and sweetness—less nuanced than gongfu, but wonderfully convenient.

🫖 Equipment You'll Need

A porcelain gaiwan is the traditional vessel for brewing oolongs like milk oolong, and there's good reason: its smooth, non-porous surface won't absorb or distort the tea's delicate buttery aroma, and the wide bowl lets you watch the tightly rolled leaves unfurl. The lid-and-saucer design gives you precise control over pour speed and steeping time, essential when you're pulling five or six nuanced infusions from the same leaves.

Expert Tip: Water Temperature Matters

If your water is too hot (full rolling boil, 100 °C), you risk scorching the leaves and losing the creamy sweetness. Let the kettle rest for 30–60 seconds after boiling, or use a thermometer to hit 90–95 °C—the sweet spot for most oolongs.
