Dong Ding Oolong – Frozen Summit Oolong

Comprehensive Guide to Dong Ding Oolong Tea

Historical Origins
Dong Ding Oolong originated in mid-19th century Taiwan’s Lugu Township, Nantou County, developed from Wuyi tea cultivars transplanted from Fujian. Its signature “cloth-wrapped kneading” technique took shape early on, while the 1970s breakthrough with Jin Xuan cultivar brought it global fame. Designated a Taiwanese Geographical Indication product in 2008, it’s revered as the “Sage of Taiwanese Teas.”

Tea Characteristics
1. Appearance & Color
– Dry Leaves: Tight semi-spherical pellets (~0.5cm diameter), jet-black with oily sheen and frost-like trichomes; medium-roasted versions show “dragonfly head” red spots.
– Wet Leaves: Unfurled with “green leaf red edge” contrast, thick satiny texture, and rounded serrations.

2. Sensory Experience
– Liquor Color:
? Light oxidation: Honey-yellow with green tint
? Medium roast: Amber gold
– Aroma:
? Varietal: Jin Xuan’s milky notes, Si Ji Chun’s osmanthus florals
? Processing: Charcoal roast, stewed fruit (medium-fire teas)
– Flavor:
? Velvety rice-broth texture with distinctive “cool mineral” throat feel
? Almond-like sweetness in aftertaste

Brewing Artistry
1. Double-Walled Glass Infuser Method (Aroma & Visuals)
– Tools: Concentric glass cup with removable inner strainer
– Steps:
① Load 5g tea, activate with 95°C spiral pour
② First steep 40 sec into outer cup, savor aroma
③ Remove inner strainer to prevent overbrewing; +15 sec per subsequent steep

2. Chaozhou Red Clay Pot Tradition
– Tools: Mengchen-style zhuni pot (150ml), white porcelain cups
– Key Techniques:
① “Pot-waking”: Preheat pot, add 8g tea, steam-lock for 1 minute
② “Phoenix nods thrice” pouring technique; first 3 steeps @10 sec
③ Steeps 4-6 @20 sec to observe roast evolution
④ Aged teas pair well with aged tangerine peel

3. Ice-Mist Cold Brew (Modern Twist)
– Process:
① 5g tea + 600ml Alishan spring water
② 12-hour cold extraction in vacuum flask @4°C
③ Filter, add sakura salt to amplify sweetness

Core Production Techniques
– Withering: Indoor oxidation with precision climate control (22°C)
– Kneading: 25-30 cloth-ball rolling sessions for pellet shaping
– Roasting: Longan wood charcoal low-temp baking (60-70°C)

(Note: Premium Dong Ding must achieve “Three No’s”: no astringency, no throat tightness, no greenish rebound.)
