Brewing Steps
Select Your Oolong
Choose based on oxidation level: light (10-30%), medium (30-50%), or dark (50-70%). Adjust water temperature accordingly.
Warm & Rinse
Warm your teaware thoroughly. Add leaves, give a quick 5s rinse to awaken them, then discard water.
Observe the aroma of rinsed leaves – it reveals the tea’s character.
First Infusion
85-95°C water, 20–25s. Pour completely into fairness cup.
Focus: Initial aroma, light floral notes, and texture.
Second Infusion
25–30s. Notice how tightly rolled leaves begin to unfurl, releasing more complexity.
Progressive Steeping
+5s each steep. High-quality Oolong reveals different notes in each infusion.
Peak complexity usually occurs in infusions 3-5.
Final Infusions
When flavor lightens, increase to 45-60s per steep. Enjoy the subtle, sweet finish.

Cultural Insight
Oolong tea, meaning “Black Dragon” tea, represents the art of partial oxidation – a technique perfected over centuries in China’s Fujian and Guangdong provinces. The most skilled tea masters can create dozens of oxidation levels, each producing unique flavor profiles.
Traditional Oolong processing involves withering, bruising, partial oxidation, fixation, rolling, and drying. This complex process creates the characteristic floral aroma and layered complexity that makes Oolong one of the most sophisticated tea categories.
Troubleshooting Common Issues
Too Bitter/Astringent
Lower water temperature (85°C), shorter steep times, or use fewer leaves.
Weak Flavor
Increase leaf amount, use hotter water (up to 95°C), or extend steep time.
Leaves Don’t Unfurl
Use hotter water, longer first steep, or ensure complete pouring between infusions.
Flat Aroma
Pre-warm teaware thoroughly, use mineral water, or try aroma cups.
Recommended Teaware
