History

Niulan Keng (Bull Pen Pit) is one of Wuyi's legendary 'Three Pits and Two Streams' (san keng liang jian) - the most prized micro-terroirs within the zhengyan core. The narrow gorge creates a unique microclimate: limited sunlight, high humidity, mineral-rich runoff from surrounding cliffs, and constant mist. Rou Gui grown here is considered the pinnacle expression of the cultivar, with the most intense mineral backbone and the deepest 'yan gu' (rock bone) of any Wuyi production area.

Processing

Meticulous Wuyi processing with extra care: hand-picked, sun-withered, carefully tossed for controlled oxidation (40–50%), and given a precise medium charcoal roast designed to amplify the terroir's mineral character without masking it.

Tasting Notes

Appearance

Dark, tightly twisted leaves with excellent uniformity. The liquor is deep amber with remarkable clarity and a thick, almost oily texture.

Aroma

Intense cinnamon spice layered over profound mineral depth - like breathing in cinnamon near a mountain spring. The aroma has a penetrating quality that lingers in the gaiwan for hours.

Taste

The benchmark for Rou Gui: explosive cinnamon that's simultaneously spicy and sweet, underpinned by deep, lasting minerality. The 'yan gu' (rock bone) is unmistakable - a structural mineral presence that lingers for minutes after swallowing. This is terroir-driven tea at its most compelling.

Brewing Guide

Western Style

  • Leaf: 5g per 200ml
  • Water: 100°C (212°F)
  • Time: 2–3 minutes
  • Infusions: 4–6 infusions

Gongfu Style

  • Leaf: 8g per 110ml
  • Water: 100°C (212°F)
  • Time: 8s first, +5s each subsequent
  • Infusions: 10–15 infusions

Step-by-step

  1. Boil the water. Full rolling boil at 100°C. This tea demands maximum heat. Tip: Use the best water you have - this tea will reveal every nuance of your water quality.
  2. Warm and rinse. Thoroughly warm gaiwan. Quick 3-second rinse. Tip: The wet leaf aroma from Niulan Keng is unforgettable - pure cinnamon and stone.
  3. First infusion. Just 8 seconds. Pour immediately. Tip: Even this brief steep carries remarkable mineral depth.
  4. Core steeps. 8–12 seconds each for steeps 2–8. This is the heart of the session. Tip: Pay attention to the 'yan gu' - that structural mineral sensation that anchors every sip.
  5. Endurance steeps. 15–40 seconds for steeps 9–15. Niulan Keng's endurance is extraordinary. Tip: At steep 12, this tea still has more complexity than most teas have at steep 3.
