The History: The Ancestor of Ripe Pu-erh

Liu Bao tea is a historic “Hei Cha” (Dark Tea) from Guangxi Province with a history spanning over 1,500 years. During the late 19th and early 20th centuries, it was the “life-saving tea” for Chinese miners in Southeast Asia (Malaysia and Singapore) because of its cooling properties and its ability to settle the stomach in hot, humid climates.

Crucially, Liu Bao is the technological ancestor of Ripe (Shu) Pu-erh. The “Wet Piling” fermentation technique used to make Ripe Pu-erh in the 1970s was actually adapted from the traditional fermentation methods of Liu Bao. While Pu-erh is more famous today, Liu Bao remains the “soul” of dark tea for many traditional drinkers.


Geography: The Mists of Cangwu

The home of Liu Bao is Cangwu County in the city of Wuzhou, Guangxi.


Decoding the Grades & Characteristics

Liu Bao is prized for its “Four Perfections” (Si Jue): Red, Thick, Pure, and Aged.

1. Traditional vs. Modern

2. The “Betel Nut” Aroma (Bing Lang Xiang)

The most sought-after characteristic of high-quality aged Liu Bao is a natural aroma of betel nut (a common palm nut in the region). It is a cooling, slightly woody, and nutty scent that is the hallmark of a masterfully aged batch.


How to Identify Quality

A good Liu Bao should be “clean” and “warming,” with no hint of mold or mustiness.

Reputable Brands & Where to Buy

Liu Bao is the “medicine” of the tea world. It is the perfect tea to drink after a heavy meal or on a humid day. For the best experience, use boiling water and a purple clay (Yixing) teapot to bring out its deep, woody soul.
