Lapsang Souchong is the world's earliest black tea. It is produced in the Tongmu Pass area of Xingcun Town, Wuyi Mountain, Fujian, located at an altitude of 1000–1500 meters in the northern section of Wuyi Mountain. The terrain is high and steep, with shrubs growing among the mountains. The climate is cool in summer and warm in winter, with an average annual temperature of 18°C, annual rainfall of about 2000 mm, and year-round mist and fertile soil. The Tongmu Pass area of Xingcun Town has been designated as a World Natural and Cultural Heritage site and listed as a Category A nature reserve by UNESCO. Therefore, the production scale of Lapsang Souchong black tea is limited, making it a treasure among teas.

The creation of Lapsang Souchong has a very interesting story: During the late Ming and early Qing dynasties, the situation was unstable, and Tongmu was a strategic passage into Fujian. Once, an army entered Fujian from Jiangxi via Tongmu and occupied a tea factory. It happened to be the tea-picking season. The soldiers used the tea leaves on the ground as bedding and slept there overnight. The tea leaves, due to pressure and prolonged storage, fermented and turned red. To salvage the loss, the tea farmers used flammable pinewood to heat and dry the tea, creating a unique, rich pine smoke flavor resembling dried longan. Unexpectedly, the taste was excellent and distinctive. This special flavor was well-received and loved by consumers both at home and abroad. Thus, Lapsang Souchong, also known as Tongmu Pass Souchong, came into being.

Lapsang Souchong black tea has a robust appearance, dark and lustrous color. When brewed, the liquor is thick red, with a long-lasting aroma carrying a pine smoke scent. The taste is rich and mellow, with a longan-like flavor. When milk is added, the tea aroma remains undiminished, forming a syrupy milk tea with an even more brilliant color. Due to its unique quality characteristics, the special environment of the Tongmu Pass tea-growing area (high mountains produce fine tea), and the special processing techniques, it has won the hearts of many tea lovers.
