Oolong Tea Processing: The Delicate Balance Between Green and Black Tea


Oolong represents tea artistry at its peak - neither green nor black, but a spectrum in between. The exact oxidation level (10-70%) creates vastly different flavor profiles.
1. Step-by-Step Oolong Processing
A. Solar Withering (2-3 hours)
Softens leaves for bruising
Develops first floral aromas
B. Indoor Withering & Tossing
Leaves shaken in bamboo trays every hour
Develops the signature "red edge, green center"
C. Fixation
Pan-fired at precise moments to lock in flavors
High mountain oolongs often receive lighter firing
See how altitude affects taste in our High Mountain Tea Guide.
2. Regional Processing Variations
Oolong Type | Oxidation | Firing | Unique Step |
Anxi Tieguanyin | 15-25% | Light | Repeated ball-rolling |
Wuyi Rock Tea | 50-60% | Heavy | Charcoal roasting (up to 20 hours) |
Oriental Beauty | 60-70% | None | Insect-bitten leaves |
Fun Fact: Oriental Beauty's honey notes come from leafhopper insects' enzymatic reaction.
3. Roasting: The Final Touch
Light Roast (3-6 hours): Preserves floral notes
Medium Roast (8-12 hours): Develops caramel tones
Heavy Roast (15+ hours): Creates mineral "rock taste"
