What is oolong?
Oolong (烏龍) is a partially oxidized tea. Where green tea is barely oxidized and black tea is fully oxidized, oolong lives in the wide middle — anywhere from about 10% to 70%. That range is exactly why Taiwan can offer such astonishing variety from a single category.
The Taiwanese oolong spectrum
Picture a line. At the light end sits Baozhong: barely oxidized, green, intensely floral. Move along to high mountain oolong, then rolled, roasted Dong Ding. At the dark end is Oriental Beauty, heavily oxidized and naturally honeyed thanks to a tiny leafhopper insect.
Who each style is best for
- New to fine tea: high mountain oolong — sweet and easy.
- Like coffee or roasted flavors: Dong Ding — caramel and depth.
- Love floral, delicate cups: Baozhong.
- Prefer fruity, honeyed tea: Oriental Beauty.
How to brew it
Brew gongfu style: a small vessel, a generous amount of leaf, water just off the boil (90–95°C), and a series of short steeps. Your first infusion might be 25 seconds; extend each later one. This reveals how the tea changes cup to cup.
What to compare it with
If you know Chinese Tieguanyin or Wuyi oolong, Taiwanese oolong will feel cleaner and sweeter, with a stronger high mountain tradition. Against Japanese green tea, it is more roasted-floral and less grassy.
Buying notes
Good everyday Taiwanese oolong runs roughly NT$400–1,500 per 150g; high mountain competition lots cost much more. Buy small amounts of several styles first to find your preference, and look for a recent harvest season on the label.
What beginners get wrong
Using too little leaf, water that is too cool, and one long over-steep. More leaf, hotter water, and shorter repeated steeps will transform your results.
Frequently Asked Questions
- Is oolong green or black tea?
- Neither — it's its own category. Oolong is partially oxidized, between unoxidized green tea and fully oxidized black tea. The degree of oxidation varies widely across Taiwanese styles.
- How many times can I re-steep oolong?
- A quality Taiwanese oolong is built for multiple infusions. Brewed gongfu style, expect 5–8 steeps, with the flavor evolving each time.
- Does oolong have caffeine?
- Yes, moderate amounts — typically less than coffee and roughly comparable to black tea, though it varies by leaf and brewing.
- What is the best oolong for a beginner?
- A spring or winter high mountain oolong. It is sweet, low in bitterness, and forgiving, making it the easiest fine oolong to enjoy from the first cup.
