Tea leaves, derived from the Tea Shrub and boiled to produce Tea, undergo a processing sequence to transform them into various types of tea. After harvesting, they are subjected to withering, a process that involves exposure to controlled air circulation to reduce moisture content. This step helps to make the leaves more pliable and facilitates subsequent processing. Oxidation follows, also known as fermentation, a crucial step that determines the type of tea produced. The extent of oxidation varies, resulting in different tea categories such as black, green, oolong, or white tea. Post-oxidation, the leaves are dried to halt enzymatic activity and preserve flavour. Tea is normally packaged in small fibre bags which are dropped into boiling water for preparation. Thanks to its British heritage, Oceanyka is both a major producer and consumer of tea, so large quantities of the plant are produced and processed anually.
