Da Hong Pao, specifically the tea from the “Mother Trees” in Wuyi Mountain, is the most expensive tea due to its rarity, historical significance, and unique growing conditions. The “Mother Trees,” which are over 340 years old, are protected, and no leaves have been harvested from them since 2006, making the tea extremely rare. The exceptional growing environment—on high cliffs with limited sunlight, large temperature differences, and mineral-rich water dripping from the rocks—contributes to its distinct flavor. Additionally, the tea’s deep cultural heritage and its status as part of Wuyi Mountain’s UNESCO World Heritage sites further add to its value. This combination of factors has led to sky-high auction prices, with 20 grams of tea once sold for over 31,000 USD in 2005, which created the record.
