The tea we source from Argentina is grown in the highland region of the Misiones province in the northeast of Argentina. The climate is hot and humid and the land is relatively flat which allows, after decades of adapting the plantations as well as the industrial capacities, an innovative mechanized harvesting and manufacturing process. Tea is harvested during Argentina's summer months of October to May.

China is well known as the birthplace of tea and is the largest producer of tea in the world. We buy our tea from carefully selected tea gardens across different regions including Yunnan, Hunan, Zhejiang, Fujian, Jiangxi, Hubei, Anhui, Guizhou and Chaongqing. While the majority of tea in China is grown by smallholder farmers who cultivate their own tea bushes and sell the green or slightly processed leaves to surrounding factories, we buy from both estates and smallholder farmers. In China, tea is grown from March to late October.

India is the second largest producer of tea in the world and we source our tea from three different regions: Assam in the North East, where the Brahmaputra river meanders through, Darjeeling in the foothills of the Himalayas and tea gardens in the hilly and humid South. Each region has its own distinct flavour, from strong and malty Assam to light and elegant Darjeeling. We buy from large plantations, with large number of workers living on the estate with their families.

In Indonesia, tea is grown all year round on the islands of Java and Sumatra which benefits from rainforest, mountains and rich volcanic soil. Indonesia is the 7th largest tea producer in the world. Approximately 70% of Indonesian tea is grown on the highlands of the island of Java. Tea from Java has sweet, smooth and slightly spicy taste. We source tea from state-owned companies, private tea estates and smallholder farmers.

Due to Kenya's equatorial climate, tea can be grown year-round. It is the top tea-producing country in Africa. We source our tea from the highlands of Kenya, in Nandi, Kericho and in the foothills of Mount Kenya. Harvesting is a mixture of machine and hand plucking in Kenya. The tea we buy comes from smallholders and private estates; approximately half a million people are involved in tea production in Kenya. Kenyan tea has a good, strong and balanced flavour.

We source our Sri Lankan tea, also known as "Ceylon tea" from both large plantations, as well as private tea factories who process smallholder leaves. The tea growing areas are in the centre and south of the country and are categorised by the elevation at which tea is grown (high, medium or low grown) as each area has their own taste characteristics. Tea is grown year-round here and almost 5% of the population work in the tea industry.
