As we have learned in "How do we know Chinese drank tea first?", China is the home of tea. She is also the origin of all tea seeds and tea production techniques now used by tea producing countries across the world. Important tea producing regions are ideally placed geographically and climatically for tea plantation. Besides this natural advantage, their history also plays a significant part in developing a successful tea industry (More in "How tea got to the other parts of the world?"). The production of tea, from growing, harvesting, processing to packing, required great attention and effort. Every step of the process has a crucial impact on quality.
