Oolong tea—also called green tea in the broad sense of semi-fermented Chinese tea—has a simple rule:
same leaves, different brewing, totally different cup.
If your brew tastes harsh or flat, it’s rarely the tea. It’s usually water temperature, teaware, or slow pouring.
This guide covers the universal method first, then the two icons:
- Phoenix Dan Cong (Fenghuang Dancong)
- Wuyi Rock Tea (Wuyi Yancha)
What Is Oolong Tea in One Line
Oolong is a semi-oxidized tea between green and black tea.
It shows “green leaf with red edge” when brewed well, and can last 6–10 infusions.
Main families:
- Guangdong: Phoenix Dan Cong
- Fujian north: Wuyi rock tea (Da Hong Pao, Rou Gui, Shui Xian)
- Fujian south: Tie Guan Yin
- Taiwan: Dong Ding, High Mountain oolong
Prepare Before Brewing
1. Water
Use soft mountain spring water or low-mineral bottled water.
Avoid tap water with chlorine—it kills aroma.
Lu Yu wrote in Classic of Tea: “Mountain water best, river water middle, well water last.”
2. Teaware: Gaiwan vs Zisha
|
Teaware
|
Best for
|
Why
|
|---|---|---|
|
White porcelain gaiwan (110–150ml)
|
Phoenix Dan Cong, Tie Guan Yin, new rock tea
|
No scent absorption, fast drain, easy to smell aroma
|
|
Yixing zisha pot
|
Aged rock tea, heavy-roast oolong
|
Softens fire taste, thicker body, but absorbs high floral notes
|
|
Glass pot
|
Taiwan high mountain, light oolong
|
Watch the leaves, but heat loses faster
|
Rule of thumb:
- High aroma → gaiwan
- Heavy rhyme / roast → zisha
3. Temperature
Most oolong: 100°C boiling water
Light fragrant Tie Guan Yin: 95–98°C
Never use warm water—it locks the aroma inside.
Standard Oolong Brewing Steps
Use 110ml gaiwan as base.
Step 1 – Warm the ware
Rinse gaiwan, fair cup, and cups with boiling water. Keeps heat stable.
Step 2 – Add tea
- 2–3 people: 6–8g
- 4–6 people: 8–10g
- Dan Cong: fill 2/3 of gaiwan
- Rock tea: 1/2–2/3 of gaiwan
Step 3 – Rinse (not drink)
Pour boiling water, 1–2s, discard.
Just wake the leaves, not steep.
Step 4 – Brew by rhythm

Core rule: fast in, fast out, drain completely.
Leftover liquid = bitter next cup.
Mnemonic:
First water, second tea, third and fourth are the soul.
Phoenix Dan Cong: Brew for the Aroma
Dan Cong is “perfume in tea form”—honey orchid, duck shit, cinnamon, gardenia.
Key points:
- Gaiwan only, not zisha (zisha eats the smell)
- 100°C, high pour along the wall
- 0–5s out, never sit the cup
- No cover sitting, no leftover soup
If you blink, it goes bitter. Speed is the recipe.
Wuyi Rock Tea: Brew for the Body
Key points:
- Zisha or gaiwan both OK; zisha rounds the fire
- 100°C hard pour, let leaves roll
- Slightly longer than Dan Cong in early cups
- From 4th cup, extend steeping slowly
Good rock tea holds 8–12 brews.

Common Mistakes
- Using 80°C water “to protect the tea”
- Soaking instead of rinsing the first pour
- Leaving tea soup in the gaiwan
- Using zisha for high-fragrance Dan Cong
- Re-boiling the same kettle all day
Final Takeaway
Brew oolong like this:
Boiling water + right ware + fast drain + no leftover.
Dan Cong = protect the smell.
Rock tea = unfold the depth.
Do that, and the same leaves taste like the tea house.
