Technical
1. The Genetic Variable: Heirloom Qun Ti Zhong Unlike the widely planted clonal Longjing #43, Qun Ti Zhong is the original heirloom variety propagated by seeds.
-
Structural Difference: Seed-grown bushes possess a deep taproot system, allowing for higher mineral absorption from the rocky soil of the core region.
-
Flavor Logic: It yields a more complex, layered profile. While clonal varieties prioritize early-season sweetness and uniform appearance, Qun Ti Zhong offers a robust “Bean Aroma” (Dou Xiang) paired with a persistent “Rock Rhyme” (Yan Yun) and a powerful returning sweetness (Hui Gan).
2. Authentication & Traceability The primary risk in the Longjing market is provenance mislabeling. To mitigate this, each 50g box is equipped with a unique, serialized anti-counterfeit label from the Hangzhou West Lake Longjing Tea Management Association.
-
Verification: This label acts as a physical credit backup, confirming that the tea was harvested within the strictly defined geographical borders of the West Lake core zones and processed according to regulated standards.
3. Sensory Profile
-
Dry Leaf: Flat, smooth, and sturdy. The color is a natural yellowish-green (often described as “Imperial Gold” or “Bao Guang”), indicating traditional pan-firing techniques.
-
Liquor: Bright apricot-green with high clarity.
-
Palate: Mellow and full-bodied. The initial floral notes transition into a deep, nutty sweetness with a clean, refreshing finish.
-
Infused Leaf: Tender, even, and “fat” buds, showing high vitality and enzymatic integrity.
Critical Variable & Risk Analysis
I. Thermal Sensitivity (Brewing Mechanics)
-
Variable: Water Temperature.
-
Logic: High-grade green tea contains delicate amino acids that degrade under extreme heat.
-
Threshold: The optimal temperature is 85°C (185°F).
-
Risk: Using boiling water (100°C) will cause the premature release of caffeine and polyphenols, resulting in an astringent liquor and a “cooked” vegetal smell that masks the orchid fragrance.
II. Preservation Logic (Oxidation Control)
-
Variable: Ambient Temperature and Humidity.
-
Precondition: Green tea is unoxidized and highly reactive.
-
Protocol: For long-term storage, the tea must be sealed and kept at -18°C (0°F).
-
Risk: Exposure to light, air, or room-temperature environments for more than 48 hours will result in a noticeable loss of “freshness” (Xian Du) and a yellowing of the liquor.
III. Aesthetic Variation
-
Variable: Leaf Uniformity.
-
Observation: Because Qun Ti Zhong is seed-grown, natural genetic variation exists.
-
Identification: Subtle differences in leaf size and shape are normal. A “perfectly identical” appearance is often a marker of clonal tea (Longjing #43) rather than the heirloom variety.
