Terroir & Climate
At 319 metres elevation in Misiones province, Las Treinta occupies a relatively low-altitude site in Argentina's subtropical tea-growing region. Estates at this latitude and elevation typically experience warm, humid conditions with year-round growing potential, though seasonal variations in temperature and rainfall generally influence flush intensity. The moderate altitude tends to favour steady vegetative growth rather than the slower maturation associated with high-elevation gardens.
Misiones province lies in Argentina's far north-east, bordering Paraguay and Brazil, and represents the southernmost significant concentration of commercial tea cultivation in South America. The region's red soils and consistent moisture levels generally support vigorous tea plants, though estates at this elevation often produce leaf with less aromatic complexity than their counterparts at higher altitudes. The terroir typically yields a straightforward, robust character suited to blending and bulk markets.
Tea Produced
Las Treinta produces black tea. Estates in Misiones at comparable elevations generally yield a cup with malty, straightforward body and moderate astringency. The profile tends toward the robust end of the spectrum, with less floral or fruity complexity than high-grown teas from other origins. This style is typically well-suited to blending applications and markets that favour strength and colour over nuanced aromatics.
Supply Chain & Market Position
Las Treinta is recorded as supplying Finlays, a major global player in tea sourcing, blending, and ingredient supply. Finlays' customer base includes multinational brands and private-label programmes, which suggests that Las Treinta's output is likely destined for blended products and foodservice applications rather than single-origin retail. The relationship positions the estate within established international supply chains, providing access to volume buyers who value consistency and certification.

Certifications & Ethics
Las Treinta holds organic certification, which prohibits synthetic pesticides, herbicides, and fertilisers and requires documented traceability. For buyers, organic status offers a point of differentiation in retail and foodservice markets where consumer demand for certified sustainable products continues to grow. On the ground, organic protocols typically require more labour-intensive weed and pest management, as well as investment in compost and biological inputs.
