What is Pu-erh Tea?
Pu-erh is a fermented and aged tea, produced from the leaves of the camellia sinensis plant and originating from the Yunnan province of China. A traditional Chinese tea whose cultivation history stretches back hundreds of years, pu-erh brews up a deep, dark color and has a rich, mellow, earthy flavor. Pu-erh is enjoyed by collectors and novice tea drinkers alike, and has seen a surge in popularity in recent years as more people become familiar with this unique tea.
Pu-erh is a type of heicha, or Chinese black tea. In China, what westerners typically refer to as black tea is called red tea, with black tea referring only to teas such as pu-erh that are fermented and aged after having undergone the oxidation process.
While the exact history of pu-erh and other heicha has been lost to time, the tea most likely has its origins in the Silk Road and other such extensive east-west trade routes. As a fermented and aged tea, pu-erh travelled well, and even improved its flavor, over the long journey it took to reach far off destinations. As such, it became a valuable trade commodity, and quickly spread throughout Asia and beyond.
The tea is named after the city of Pu-erh in Yunnan province, a famed trading post for heicha in imperial China. Bordering Laos, Myanmar, and Vietnam in the southwestern part of China, Yunnan province had extensive trade ties to the west and throughout Asia during imperial times. Today, only tea originating from Yunnan province is legally allowed to be sold as pu-erh, and much of the tea is still processed in the city of Pu-erh itself!
How Pu-erh is Made
While most teas go through a process of oxidation, few are truly fermented as pu-erh and other heicha are. The tea is first harvested from a varietal of camellia sinensis known for its large leaves and grown in southwestern China. Leaves are most prized if they are picked from older, wild growing trees. Tea harvested from plants that are cultivated but have wild origins, called “wild arbor” trees, is also valuable, while tea grown from plantation bushes is less desirable. The time of harvest also affects the tea, with pu-erh of the highest quality harvested in the spring.
Harvested pu-erh is then dry-roasted in a process called “killing the green,” after which the tea is lightly bruised by rolling and rubbing, and then sun dried. While this process largely halts oxidation, a minimal amount of oxidation continues to occur as it dries, which contributes to the unique flavor and composition of pu-erh.
The tea is then fermented. Shou cha, or ripened pu-erh, undergoes an accelerated process, similar to composting, by fermenting the tea in a humid environment over a time period of months to years. Sheng cha, or raw pu-erh, undergoes a slower, traditional fermentation process, which can take years. Both forms of pu-erh can be further aged in order to continue to develop the flavor of the tea. Similar to wine, pu-erh grows in the depth and complexity of its flavor as it matures, and often increases in both rarity and price with age. Pu-erh that has been aged for many decades can sell for thousands of dollars a pound!
Pu-erh is often pressed into a variety of shapes, such as cakes, bricks, or flat squares pressed with Chinese characters. These can be decorative as well as for consumption.
Pu-erh Health Benefits
Pu-erh has a long history of being used in China for its medicinal benefits in traditional herbal medicine. Like other varieties of camellia sinensis, pu-erh is full of antioxidants, and has an uplifting, energizing effect thanks to its caffeine content, which is similar to black tea and about half that of a cup of coffee. The fermentation process that pu-erh undergoes produces a tea with other unique health benefits, as well. Pu-erh is often used to aid digestion, lower blood pressure, and even to help lose weight.
Pu-erh aficionados often speak of a body high that accompanies drinking this tea, which warms you from the inside out and relaxes both the body and the mind. While studies concerning the potential effects of pu-erh are still ongoing, evidence suggests that pu-erh has a wealth of health benefits even over and above other types of tea!
How to Prepare Pu-erh
If using a cake or brick of pu-erh, the leaves can be flaked off from the larger whole using a pu-erh knife. The tea should be rinsed by pouring boiling water over the tea and then quickly discarding the liquid in order to remove impurities and prepare the tea for further infusions. Boiling water is then poured over the tea to steep.
Pu-erh is often prepared in a yixing pot or gaiwan using the traditional Chinese Gongfu method. In this method, the tea is steeped in successive infusions, with the first infusions steeping only a few seconds, and later infusions steeping for several minutes. Pu-erh teas prepared in this way can be infused many times, with each successive steeping producing a mellower flavor and exposing different nuances in the taste of the tea.
If preparing in a western style teapot or cup, steep the leaves for one to five minutes before enjoying. Pu-erh prepared in this way can also be steeped several times.
