Terroir & Climate
At 457 metres above sea level in the Misiones region of north-eastern Argentina, Las Marias North occupies a relatively low elevation within the subtropical belt. Estates at this latitude and altitude typically experience warm, humid conditions with reliable rainfall distributed through much of the year, characteristics that generally support vigorous vegetative growth and year-round or extended harvest windows.
The moderating effect of altitude in this region is less pronounced than in high-elevation equatorial estates; instead, the interplay of latitude, consistent moisture and fertile red soils tends to shape the growing cycle. Leaves grown under these conditions often develop quickly, with moderate polyphenol accumulation, and are generally suited to robust oxidised styles. The subtropical terroir of Misiones is better known for yerba mate cultivation, but tea production here draws on similar climatic advantages.
Tea Produced
Las Marias North produces black tea. Estates in this part of Argentina at comparable elevations typically yield teas with a straightforward, malty character and good body, though the cup profile tends to be less complex than that of high-grown teas from traditional origins. The oxidised leaf often displays a reddish-brown infusion and can offer a smooth, rounded flavour suitable for blending or everyday drinking. While Argentina's tea industry remains modest in global terms, the terroir of Misiones generally supports approachable, consistent blacks.
Supply Chain & Market Position
Las Marias North is recorded as supplying Morrisons, one of the United Kingdom's major supermarket chains. This relationship places the estate within the supply chain of a high-volume retail buyer, indicating that its output meets the quality, traceability and compliance standards required by British supermarket procurement. Supplying a retailer of Morrisons' scale suggests the estate is oriented towards the commodity and blended tea markets, where consistency, competitive pricing and volume capacity are typically prioritised over single-origin premiums.
