Yuhuan volcano tea is a type of black tea grown near the Shifeng Mountain volcano site in Taizhou.

The tea garden is located in Fengyang village, Damaiyu sub-district, Yuhuan city. It was established in 2009 and covers a total area of over 700 mu (46.66 hectares).

The volcano tea contains a lot of nutrients due to the area's unique soil and island climate. It has two to three times more selenium, zinc, and amino acids than green tea.

Lin Zhaoshui, president of Zhejiang Long'e Volcano Tea Co Ltd, claims that the tea is free of pesticides.

"Herbicides cost about 10,000 yuan ($1,538.46), but we spend more than 300,000 yuan on manual weeding every year. Although the cost has increased nearly 30-fold, we feel it is worth it,” Lin said.

The volcano tea manufacturing process involves 12 steps, twice as many as in regular teas.

In order to decrease internal heat, the volcano tea is stored in the refrigerator for 2 months before being put on sale, according to Lin.

This year, the volcano tea manufacturing process became a Taizhou intangible cultural heritage item.
