Terroir & Climate
At 65 metres above sea level, Cheng Chiuan sits in the low-elevation band typical of Taiwan's northern tea-growing districts. Estates at this altitude in Sanxia generally experience a subtropical climate with warm, humid conditions year-round and significant rainfall, particularly during the summer monsoon season. The lower elevation typically allows for a longer growing season and more frequent harvests compared to high-mountain estates, though temperatures can be higher and day-night temperature differentials less pronounced.
Low-elevation sites in northern Taiwan tend to benefit from rich alluvial soils and consistent moisture, conditions that generally favour vigorous growth. The warm, humid environment at this altitude typically encourages faster leaf development, which can influence both the picking schedule and the processing methods employed. Sanxia District's proximity to Taipei and its established tea-growing tradition mean that estates in the area often work within a framework of both artisanal and commercial production.
Tea Produced
Cheng Chiuan produces green, oolong, and black teas. Low-elevation estates in northern Taiwan typically yield teas with fuller body and more robust flavour profiles than their high-mountain counterparts. Green teas from this altitude range often exhibit vegetal, grassy notes with a rounded mouthfeel, while oolongs tend toward more oxidised styles with honeyed, floral, or toasted characteristics depending on processing. Black teas from the region generally show malty sweetness and a smooth, approachable character. The warm growing conditions at 65 metres typically encourage leaf that processes into teas with good colour and strength.
