Gorreana is a Portuguese company headquartered in São Miguel Island, Azores. In operation since 1883,[1] it is the oldest tea plantation in Europe.[2] The company produces black and green tea. Green and black tea plantations were introduced to the island in the 19th century, from seeds brought by ships returning from the Eastern world and with the help of technical expertise provided by a Chinese man called Lau-a-Pan and his interpreter Lau-a-Teng.[3] By the early 20th century, 10 separate factories and almost 50 tea plantations were thriving on the island.[4]
