Terroir & Climate
At 404 metres elevation in Chiangrai, the estate occupies a lowland to mid-hill position in Thailand's northernmost tea-growing region. Estates at this latitude and altitude typically experience a tropical monsoon climate with distinct wet and dry seasons, which tend to influence the rhythm of flushing and the intensity of leaf development. The relatively modest elevation generally favours year-round growing conditions, though the cooler dry season from November to February often produces slower leaf growth that can concentrate certain biochemical compounds.
The Chiangrai area is characterised by its position in the Golden Triangle region, where soils are often derived from weathered granite and alluvial deposits. Estates at this elevation range typically see warm daytime temperatures moderated by seasonal rainfall patterns, conditions that generally support robust vegetative growth. The interplay between monsoon moisture and dry-season stress tends to shape the leaf's physical structure and the balance of polyphenols and amino acids available for processing.
Tea Produced
Producing both black and green teas, Thai Tea Suwirun draws on leaf grown under warm lowland conditions that typically yield a full-bodied, accessible cup profile. Black teas from estates at this elevation in northern Thailand often display malty, slightly sweet characteristics with moderate astringency, while green teas tend toward a vegetal, grassy character with a softer, rounded mouthfeel. The relatively warm growing environment generally favours teas with pronounced body rather than the high-toned floral or citrus notes sometimes associated with higher-altitude production.
