Tea production begins with the cultivation of the Camellia sinensis plant, which is the source of all true teas. The leaves are typically harvested by hand, especially in high-quality tea production, and are then processed through various methods, including withering, rolling, oxidation, and drying. These steps determine the type of tea produced, such as green tea, black tea, or oolong tea. After processing, the tea leaves are sorted and packaged for distribution. Major tea-producing countries include China, India, Sri Lanka, and Kenya, each known for unique flavors and varieties. The entire process, from cultivation to packaging, plays a crucial role in the quality and taste of the final product.
