QUICK ANSWER
Oolong tea sits between green and black tea with 20-80% oxidation, creating incredible diversity. Light oolongs (185-195°F) are floral and delicate, while dark oolongs (195-205°F) are rich and roasted. Quality oolongs excel with multiple steepings—6-8 infusions reveal evolving complexity.

Understanding Oolong

01

The Perfect Balance

Oolong tea sits between green and black tea with 20-80% oxidation. This range creates incredible diversity—from light, floral varieties to rich, roasted styles.

Light Oolongs (20-40% oxidation)

  • Temperature: 185-195°F
  • Examples: Tie Guan Yin, High Mountain oolongs
  • Character: More like green tea with floral, fresh characteristics. Require gentler treatment to preserve delicate flavors

Dark Oolongs (60-80% oxidation)

  • Temperature: 195-205°F
  • Examples: Da Hong Pao, roasted Dong Ding
  • Character: More like black tea with rich, roasted, and sometimes mineral characteristics. Can handle higher temperatures

Western Style Method

02

Step 1: Choose Your Temperature

Match temperature to oxidation level. Light oolongs need cooler water (185-195°F), while dark oolongs can handle hotter water (195-205°F).

Quick Test

If the oolong looks green and fresh, treat it like green tea. If it's dark and roasted-looking, treat it more like black tea.

Step 2: Measure Tea Leaves

Use 1 teaspoon (2-3 grams) of loose oolong per 8 ounces of water. Oolong leaves are often rolled tight and will expand dramatically.
Ensure your teapot or infuser has plenty of room for the leaves to unfurl. Cramped leaves won't extract properly and may become bitter.

Step 3: First Steeping

Steep for 2-5 minutes depending on the style. Light oolongs need less time, while dark oolongs can handle longer extraction.
Steeping Guide:
  • Light oolongs: 2-3 minutes - Preserve delicate notes
  • Dark oolongs: 3-5 minutes - Extract full richness

Step 4: Multiple Infusions

Quality oolongs shine through multiple steepings. Each infusion reveals different aspects of the tea's complex character.
Re-steeping Schedule:
  • 2nd steeping: Same time or +30 seconds
  • 3rd-4th steeping: +1 minute each
  • 5th+ steeping: +1-2 minutes as needed

Gongfu Style Method

03

Why Gongfu Works for Oolong

Oolong tea was practically made for gongfu brewing. The high tea-to-water ratio and multiple quick steeps allow you to experience the tea's evolution from light and floral to deep and complex over 8-10 infusions.

Equipment Needed

  • Small teapot (100-200ml) or gaiwan
  • Fairness cup (cha hai)
  • Small tasting cups (30-50ml)
  • Tea strainer (optional)

Gongfu Method

Ratio: 1g tea : 15-20ml water (about 1:15)
Temperature: 195-205°F for most oolongs
Steeping Schedule:
  • Rinse: 5 seconds (discard)
  • 1st-3rd: 30-45 seconds
  • 4th-6th: 60-90 seconds
  • 7th+: 2+ minutes

The Flavor Journey

05

What to Expect Through Multiple Steepings

Steepings 1-2: Light, bright, and floral. The tea "awakens" and shows its most delicate characteristics.
Steepings 3-5: Peak complexity. Full body develops with balanced sweetness, floral notes, and deeper character.
Steepings 6+: Mellows to gentle sweetness with subtle roasted notes. Long, satisfying finish.

Troubleshooting

06

Bitter, Astringent Tea

Causes: Water too hot for light oolongs, over-steeping, or poor quality tea
Solutions: Lower temperature by 10-15°F, reduce steeping time, or try a higher grade

Weak, One-Dimensional Flavor

Causes: Not enough tea, water too cool, or leaves too cramped
Solutions: Use more tea, increase temperature, or ensure leaves have room to expand

Can't Taste Difference Between Steepings

Causes: Low-quality tea or rushing between infusions
Solutions: Try higher-grade oolong or take time to truly taste each steeping

Advanced Tips

07

The Rinse Technique

Pour hot water over oolong leaves for 5-10 seconds, then discard. This "rinse" removes dust and awakens the leaves for better extraction.
Especially beneficial for aged oolongs or tightly compressed teas.

Temperature Stepping

Start at lower temperature for first few steepings, then gradually increase heat to extract different compounds.
Begin at 185°F, increase to 195°F, finish at 205°F for maximum complexity.

Smell the Wet Leaves

After steeping, smell the wet leaves in your teapot or gaiwan. This reveals different aromatic compounds than the liquid tea.
Often more intense and complex than the tea's liquid aroma.

Save the Leaves

High-quality oolong leaves can be dried and re-used the next day for additional steepings with evolving flavors.
Store used leaves in refrigerator and use within 24 hours.

Why Oolong is the Perfect Tea for Learning

Oolong tea offers the most educational brewing experience of any tea type. Its wide range of oxidation levels means you can explore everything from green tea's delicacy to black tea's robustness within a single category.
The multiple steeping tradition allows you to witness how tea evolves and changes character over time—something impossible with single-steep brewing methods. Each infusion teaches you something new about flavor development, extraction, and the subtle art of tea brewing.
Whether you start with forgiving varieties like Tie Guan Yin or challenge yourself with complex rock teas like Da Hong Pao, oolong will reward your attention and patience with some of the most complex and satisfying tea experiences possible.

Master the Art of Oolong

Oolong tea brewing is a journey of discovery. Start with quality tea, experiment with different steeping times and temperatures, and embrace the traditional gongfu method to truly appreciate this remarkable tea category.
