This sheng puer is made from the purple leaves of forest tea trees in Baiyingshan. This high-mountain tea has a smooth flavor and heady floral-fruity aroma. Its smoothness comes from being grown in a cooler climate so far north, as the tea plants produce more amino acids. A highly approachable sheng puer cake from older trees with distinctive purple-hued leaves.

The highest-altitude puer tea in Yunnan

Teas produced in high elevation areas like Baiyingshan (the Baiying Mountains) often have a greater sweetness and complexity in flavor and aroma than lower-elevation teas. This is because the tea plants are strongly affected by the daily shifts from higher to lower temperatures between day and night. Research has shown that plants grown at high altitudes will produce additional catechins and amino acids which help them survive under the harsh conditions. This translates into rich and fascinating flavors in the processed tea. Black Stripe is an excellent example of how high-mountain growing conditions impact the final flavor of sheng puer.

The average elevation of tea gardens in Baiyingshan is around 2800 meters; this is the highest known elevation in Yunnan for groups of tea trees to prosper in. The oldest trees in this area are hundreds of years old.

Many tea plants in Baiyingshan have purple leaves in the spring that become greener as they mature. These plants are known by the name Hei Tiao Zi. The tea leaves for this cake were plucked from these plants in the early spring, while they still had a hint of purple. Because of this purple coloring, the dried leaves are noticeably darker than those from other trees – earning this tea the name “Black Stripe.”

This tea has gone through the stages of traditional processing for sheng puer: the tea leaves are  plucked, fried in a hot wok, and then kneaded and rolled into a long twisted “stripe” shape. The leaves are laid out across bamboo trays in thin layers and left to dry under direct sunlight. In the heat of the sunshine, the leaves wither and dry into mao cha (made but not fully finished tea) over a few days. Then the leaves are sorted and compressed into puer cakes.
