How do I brew Milk Oolong?

Use 3g per 200ml of leaf to 85–90°C (185–194°F) water and steep 2–3 minutes. Most quality Milk Oolong can be re-steeped for 4–5 infusions.

Does Milk Oolong contain caffeine?

Milk Oolong is a oolong tea and is rated "medium" caffeine. See the chemistry section on this page for cited ranges.

Where does Milk Oolong come from?

Milk Oolong is produced in Taiwan, specifically in the Various region.

Is the milky flavor in Milk Oolong natural or is something added?

Authentic Jin Xuan owes its creamy character entirely to the cultivar itself - TRES No. 12, developed by the Taiwan Tea Research and Extension Station in 1981, naturally produces a compound called nerolidol that gives a milk-like aroma and smooth texture. Unfortunately, some producers artificially flavor cheaper oolong leaves with milk or butter flavoring to mimic this effect, so buying from reputable sources is important. Genuine Jin Xuan has a subtle, integrated creaminess rather than a heavy artificial dairy taste.

Does Milk Oolong contain any actual dairy?

No, authentic Jin Xuan contains no dairy whatsoever - it is 100 percent tea leaf with no additives. The milky character is purely a result of natural aromatic compounds present in the Jin Xuan cultivar. People with lactose intolerance or dairy allergies can drink authentic Milk Oolong without any concern, though it is worth confirming with the vendor that the specific product is unflavored.

What water temperature works best for Milk Oolong, and can I over-steep it?

Jin Xuan brews best at 85 to 90 degrees Celsius - water that is too hot can diminish the delicate creamy aroma and make the cup taste flatter. For gongfu brewing, initial steeps of 30 to 45 seconds work well, with gradual increases per round. Over-steeping is relatively forgiving with Jin Xuan compared to green teas, as it tends toward sweetness rather than bitterness, but very long steeps will mute the signature floral-cream notes.

History

Milk Oolong (Jin Xuan) was developed in 1981 by the Taiwan Tea Research and Extension Station. The Jin Xuan cultivar (TTES No. 12) was bred by tea researcher Wu Zhenduo and named after his grandmother. The cultivar naturally produces a creamy, almost milky sweetness and silky mouthfeel without any added flavoring. However, the popularity of the 'milk' descriptor has led many commercial producers to add artificial milk flavoring to cheaper teas - authentic Jin Xuan gets its creaminess entirely from the cultivar itself.

Processing

Steps: Machine or hand picking → Solar withering → Indoor withering and tossing → Light oxidation (15-25%) → Kill-green (frying) → Ball rolling and drying

Lightly oxidized (15–25%) and either unroasted or very lightly roasted. Ball-rolled into spheres. The processing is similar to other Taiwanese light oolongs, but the Jin Xuan cultivar produces naturally thicker, creamier-tasting leaves. Authentic Milk Oolong has NO added flavoring.

Tasting Notes

First time? Jin Xuan, known as Milk Oolong, has a naturally smooth, creamy sweetness that genuinely resembles warm milk - it is one of the most inviting and easy-to-love teas for newcomers. If the flavor seems surprisingly rich and sweet without anything added, that is simply what a good Jin Xuan cultivar tastes like when grown and processed well.

Appearance

Tightly ball-rolled, jade green leaves. The liquor is a pale, luminous yellow-green.

Aroma

Naturally creamy and buttery with a sweet, vanilla-like warmth. Authentic versions have a subtle, elegant creaminess rather than an aggressive milk flavor.

Taste

Smooth and creamy with a natural buttery sweetness, vanilla undertones, and a clean, refreshing finish. The mouthfeel is remarkably silky. Authentic Jin Xuan tastes 'creamy' rather than 'milky' - the distinction is important.

Brewing Guide

Western Style

Leaf: 3g per 200ml
Water: 85–90°C (185–194°F)
Time: 2–3 minutes
Infusions: 4–5 infusions

Gongfu Style

Leaf: 6g per 100ml
Water: 90°C (194°F)
Time: 20s first, +5s each subsequent
Infusions: 5–7 infusions

Step-by-step

Moderate heat. Use 85–90°C water. The light oxidation means the leaves are delicate. Tip: Lower temperatures bring out more of the natural creaminess.
Gentle steep. 2–3 minutes. The cream-vanilla notes emerge best with patient, moderate brewing. Tip: If the tea tastes aggressively 'milky,' it's likely artificially flavored - authentic Jin Xuan is subtly creamy.

Common Pitfalls

Brewing at boiling point scorches the leaves and kills the creamy floral notes - use water at 85-90C instead.
Buying cheap milk oolong labeled as 'natural' is often artificially flavored with milk essence rather than the real Jin Xuan cultivar - check for Taiwanese origin and Jin Xuan (or #12) on the label.
Using hard or chlorinated tap water mutes the delicate dairy sweetness - filtered or soft spring water makes a noticeable difference.
Steeping for more than 3 minutes on early infusions turns the brew astringent and flat - keep first infusions to 60-90 seconds.
Storing it in a non-airtight container lets the light floral aroma escape within weeks - use a sealed, opaque canister away from strong odors.
