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

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

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

  1. 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.
  2. 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.

Buying Guide

What to look for

  • CRITICAL: Look for 'Jin Xuan' or 'TTES #12' cultivar - NOT just 'milk oolong'
  • Subtle, natural creaminess - not aggressive artificial milk flavor
  • Tight ball-rolled jade-green leaves
  • No added flavoring listed in ingredients

Quality indicators

  • Taiwan origin (Ali Shan, Shan Lin Xi, or Nantou regions)
  • Jin Xuan cultivar designation
  • No artificial flavoring - the creaminess should be entirely natural
  • Spring harvest for the creamiest character

Price range: $10–20 for standard Taiwanese, $25–45 for high-mountain Jin Xuan. Beware: very cheap 'milk oolong' is almost certainly artificially flavored.

Storage: Refrigerate and consume within 6 months for best creaminess.

Fun Facts

  • Most 'milk oolong' sold worldwide is artificially flavored - authentic Jin Xuan is naturally creamy without any additives.
  • The Jin Xuan cultivar was named after researcher Wu Zhenduo's grandmother.
  • Jin Xuan is one of Taiwan's most commercially successful modern tea cultivars.
  • The natural cream-vanilla character is produced by higher concentrations of lactones in the Jin Xuan cultivar's leaves.
