Anxi oolong tea processing

 

Tieguanyin stands apart for its signature Yaoqing fermentation, a hands-on process that draws out its delicate orchid fragrance. Handcrafted Tieguanyin embodies the wisdom of Anxi tea farmers—“observing the sky to guide the leaf, shaping it with the hands.” From fresh leaf to finished tea, every step relies on the subtle perception of sight, smell, and touch, allowing the tea to naturally develop its fragrance through “water flow” and fermentation. The result is leaves edged in red with a vibrant green center, and a cup with the signature orchid aroma and enduring Tieguanyin character.

 

1. Fresh Leaf Plucking: The Golden 48 Hours

Standard: Following the “medium-open leaf plucking” method—when new buds just unfurl and the first leaf is 40–50% mature, the second and third leaves on the bud are harvested. Tea farmers adhere to the “five no’s”: no breaking leaves, no folding, no crushing leaf tips, no single leaves, and no old or “fish” leaves. Using the “double-hand thumb-and-index pluck” technique, the buds remain intact, avoiding mechanical damage that could compromise the subsequent water treatment (“xing shui”).

Optimal Timing: Spring tea is harvested within seven days before or after Lixia (Beginning of Summer), autumn tea within ten days before or after Hanlu (Cold Dew). Leaves plucked between 9 a.m. and 4 p.m.—the “midday leaves”—have moderate moisture and peak aromatic compounds, with a supple, resilient texture.

2. Zuo Qing: The Dance of Enzymatic Oxidation

Sun-Wilting (Shaiqing) – Awakening in the Sunlight
Fresh leaves are laid thinly on bamboo racks or concrete with 1–1.5 jin per tray, allowing the sun to evaporate surface water (weight loss ~7–10%) and activate enzymatic activity. Leaves are considered ready when the surface loses its gloss and tips droop, taking care to avoid scorching (“dead green”). Traditionally, afternoon wilting lasts 20–30 minutes after 4 p.m.; rainy days require temperature-controlled indoor wilting.

Cool-Wilting (Liangqing) – Redistributing Moisture
Sun-wilted leaves are transferred to a shaded, ventilated area and left for ~1.5 hours, allowing moisture to return from stems to leaves, restoring leaf rigidity in preparation for shaking. Insufficient cool-wilting yields a green, astringent brew; excessive cool-wilting results in faint aroma.

Shaking (Yaoqing) – Forging the Orchid Aroma
Hand-shaking uses a 110 cm diameter circular sieve, each batch ~10 jin. Leaves are gently tossed in a figure-eight motion, causing slight edge breakage to promote polyphenol oxidation. The shake-rest cycle repeats 3–5 times:

• 1st shake (5–7 min): grassy aroma begins to dissipate, leaves slightly firm
• 3rd–4th shake (30–45 min): edges turn red, red-tinged borders appear, leaf backs spoon-shaped, floral-fruity notes emerge

Final standard: stems reddish, leaf bases green with red dots, grassy aroma gone, orchid fragrance pronounced.

3. Frying (Shaqing) – Capturing Aroma in Heat

Once shaking is complete, leaves are quickly pan-fried in a hot wok (approx. 250–300℃) to halt enzymatic activity and fix the aroma. A bamboo broom is used to stir rapidly: first, a “crackling” sound as moisture bursts, then a “rustling” as leaves crisp. Leaves turn yellow-green, slightly brittle to the touch, with floral-fruity fragrance released. Traditional guidance emphasizes the “three no’s” for frying: no frying on rainy days, no frying when leaves are wet with dew, and no frying before aroma fully develops, avoiding “stuffy” or burnt notes.

4. Rolling and Shaping – The Birth of the Spiral

Initial Rolling – Awakening the Tea Juice
Hot leaves are placed on a bamboo tray and rolled with both hands, curling leaves into strips and releasing tea juice. Pressure gradually increases and then decreases to prevent breakage.

Shaping (Baozou) – Forming the Tea Strips
Leaves are wrapped in cloth and rolled on a flat surface, forming tight strips with “dragonfly heads and spirals.” Traditionally, this involves 4–6 cycles of “rolling–initial baking–re-rolling–final baking”:

• Initial roll: 80℃ initial bake to 70–80% dryness, roll while warm to form preliminary spiral
• Re-roll: 60℃ secondary bake, roll again to tighten the strips and achieve a sandy green, glossy finish

Tea masters describe this as “setting the tea’s bones”: too little pressure yields loose strips; too much crushes fragrance.

5. Drying – Gentle Fire for Final Refinement

Tea is slowly baked at 60–70℃ until moisture drops below 6%, turning every 30 minutes to prevent local overheating. Traditional charcoal firing emphasizes “bright flame to dark flame”: initially using heat to remove water, then residual warmth to enhance aroma. The finished tea emits a stable, lingering fragrance.

From plucking to drying, handcrafted Tieguanyin requires 24–36 hours of intimate “dialogue with the tea.” Judging red edges during shaking, controlling heat in frying, sensing pressure in rolling—everything depends on the tea master’s experience. The resulting brew is golden and bright, orchid fragrance soaring, leaving a sweet aftertaste that lingers through seven infusions. This is the unique signature of traditional Tieguanyin, whose essence, though recognized as intangible cultural heritage, truly lives in the touch of the tea master’s hands and the tea leaves themselves.
