Inventor : An Peishi , a university lecturer from Sichuan , is the inventor of 'panda tea ' China is embracing the harvest season of possibly the world 's most expensive and bizarre tea . Locals dressed in panda costumes participate in the annual spring tea-picking festival in Ya'an , Sichuan Province , according the People 's Daily . Tea leaves in this plantation are known as 'panda tea ' , which is green tea cultivated with the faeces of China 's symbolic animal . The first pick is expected to sell for ¥440,000 ( £46,000 ) per kg . The man behind the brew is An Yanshi , a super panda enthusiast from Sichuan and a lecturer at Sichuan University . Since he invented the tea in November 2011 , An has collected 10 tons of panda droppings to fertilise the plantation . He promises drinkers they can expect ' a mature and nutty taste ' . Mr Yanshi said : 'Pandas have a very poor digestive system and only absorb about 30 per cent of everything they eat . Poo power : Mr An has used 10 tons of droppings of these cuddly animals since 2011 to grow green tea . 'That means their excrement is rich in fibres and nutrients . 'Just like green tea , bamboo contains an element that can prevent cancer . ' First batch of tea every year , usually picked in spring , is considered the best brew in China . An said he hoped his 'panda poo tea ' could make it into the Guinness Book of World Records as the most expensive tea . Serious fan : Mr An has a large collection of panda souvenirs including clothes and paintings .
The tea is fertilised with the dung of pandas . Panda enthusiast have been breeding them for years, and they are now being sold in shops all over China.
