Taiwan never has produced all that much tea. Moreover, the last dozen-odd years have seen a trend towards production of “ high-mountain ” teas, which has encouraged the migration of tea plantations to higher elevations and shrunk lowland tea-growing areas. This has reduced the amount of land in tea cultivation and the volume of tea being produced.
台灣茶的產量原就稀少，再加上近十餘年來冷冽清幽的「高山茶」當道，茶區往高山發展，平地茶區逐漸縮減，因而整體茶樹的種植面積和產量都逐年降低。
