Oolong Tea Guide: The Art of Semi-Oxidized Tea | Teathority

QUICK ANSWER

Oolong tea occupies the fascinating middle ground between green and black tea, with oxidation levels ranging from 20% to 80%. This wide range creates an incredibly diverse category with unmatched complexity that can be re-steeped many times.

What Makes Oolong Special

Oolong tea occupies the fascinating middle ground between green and black tea, with oxidation levels ranging from 20% to 80%. This wide range creates an incredibly diverse category - from light, floral Taiwanese high mountain oolongs to dark, roasted Wuyi cliff teas. No other tea category offers such variety within a single type.

The production of oolong requires the highest level of tea-making skill. The tea master must know exactly when to stop oxidation to achieve the desired flavor profile. This artisanal approach, combined with unique processing techniques like rolling and roasting, creates teas of extraordinary complexity that can be re-steeped many times, with each infusion revealing new flavors.

The Complex Art of Oolong Processing

Plucking: Mature leaves are selected (not just buds)
Withering: Sun withering followed by indoor withering
Tossing/Bruising: Leaves are shaken to bruise edges, starting oxidation
Oxidation: Carefully controlled to achieve desired level (20-80%)
Fixation: Heat applied to stop oxidation at perfect moment
Rolling: Shapes leaves into balls, strips, or twists
Drying: Initial drying to reduce moisture
Roasting (optional): Additional roasting for flavor development

Major Oolong Categories

Light Oolongs (20-30% oxidized)

Closer to green tea in character, with fresh, floral notes. These include:

Taiwanese High Mountain: Grown above 1,000m, creamy and floral
Tie Guan Yin (modern style): Light, orchid-like fragrance
Baozhong: Minimal oxidation, delicate and sweet

Medium Oolongs (30-60% oxidized)

Balanced between fresh and roasted notes:

Traditional Tie Guan Yin: Balanced, with fruit and floral notes
Dong Ding: Taiwanese classic, honey and fruit flavors
Oriental Beauty: Naturally sweet, honey and fruit

Dark Oolongs (60-80% oxidized)

Closer to black tea, often with roasted character:

Da Hong Pao (Big Red Robe): Famous Wuyi cliff tea, mineral and roasted
Shui Xian: Full-bodied with stone fruit notes
Rou Gui: Cinnamon-like spice, bold flavor

Skin health: Can help with eczema and atopic dermatitis

The Art of Gongfu Brewing

Oolong tea is traditionally brewed using the gongfu method, which uses more tea, less water, and shorter steeping times to extract maximum flavor through multiple infusions.

Gongfu Brewing Steps

Use 5-7g of tea for 100-150ml water
Rinse leaves with hot water (quick pour, discard)
First infusion: 20-30 seconds
Add 5-10 seconds for each subsequent infusion
Enjoy 5-8+ infusions as flavors evolve

Method	Why Choose	Specifications
Gongfu	Extracts subtle flavors, multiple profiles, social experience, maximum value	5-7g per 100ml, 20-30s first steep
Western	Convenient, familiar, single infusion	2-3g per 8oz, 185-205°F, 2-3 minutes

Selecting and Storing Oolong

What to Look For

Appearance: Tightly rolled balls or long twisted leaves
Aroma: Complex - floral, fruity, or roasted depending on style
Color: Green to brown depending on oxidation
Unfurling: Good oolongs expand dramatically when steeped

Storage Tips

Store in airtight containers away from light and odors
Roasted oolongs improve with age if stored properly
Light oolongs are best consumed within a year
Can be vacuum-sealed for longer storage
Some collectors age certain oolongs like wine

The Oolong Experience

Drinking oolong is about the journey, not the destination. Each infusion tells a different part of the story - the first might be floral and light, the third fruity and sweet, the fifth roasted and mineral. This evolution is what makes oolong special.

The Chinese have a saying: "The first cup moistens my lips and throat, the second breaks my loneliness, the third searches my barren entrails, the fourth raises a slight perspiration, the fifth purifies me, the sixth calls me to the realms of immortals, the seventh - ah, but I could take no more."

Begin Your Oolong Journey

Oolong tea rewards patience and attention. Start with a medium oxidation Tie Guan Yin or Dong Ding to experience the balance, then explore lighter high mountain oolongs or darker Wuyi cliff teas. Remember, oolong is meant to be savored slowly through multiple infusions - embrace the ritual.
