Terroir & Climate
At 68 metres elevation and a latitude of approximately 29°N, Da Zhang Shan occupies low-lying terrain in a region where tea cultivation typically benefits from warm, humid conditions and extended growing seasons. Estates at this altitude in eastern China generally experience less diurnal temperature variation than high-mountain gardens, which tends to favour vigorous growth and relatively consistent flush cycles throughout the warmer months.
Ziyang Town lies within a climatic zone that typically receives ample rainfall and moderate winter cold. Low-elevation sites of this kind often produce leaf with good body and a rounded character, though they may lack the pronounced aromatic complexity associated with higher-altitude gardens. The ability to process green, oolong, and black teas from the same estate suggests access to cultivars and seasonal windows suited to varied oxidation levels.
Tea Produced
Estates in this region at similar elevations generally yield green teas with a soft, approachable vegetal character, often less astringent than high-mountain styles. Oolong production at lower altitudes in eastern China tends to produce medium-bodied cups with floral or toasted notes, depending on oxidation and firing regimes. Black teas from such environments typically offer malty or slightly sweet profiles, with good colour and moderate tannin. The co-operative's ability to produce all three categories suggests flexible processing capability, though specific cultivar selections and finishing techniques remain unrecorded.
