Da Hong Pao is a Wuyi Rock Tea grown in China which is considered as the most expensive tea in the world. It is dark and heavily oxidized oolong tea and the reason it is so expensive is because it is rare and exclusively grown. Da Hong Pao costs INR 6,72,00 per pot. The Wuyi mountains in China’s Fujian Province are the original and natural place to grow the tea and hence it is very rare.
