Chinese dark tea, also known as Hei Cha, is a category of tea that has been cherished for centuries in China. Among its varieties, Pu-erh stands out as a unique and complex type of tea, with a rich history and a distinctive set of characteristics that set it apart from other teas. This article delves into the world of Pu-erh tea, exploring its history, types, production process, and the art of tasting.
History of Pu-erh Tea
The history of Pu-erh tea dates back to the Tang Dynasty (618-907 AD), but it gained prominence during the Ming Dynasty (1368-1644 AD) when it became a tribute tea sent to the imperial court. Pu-erh is named after the city of Pu'er in Yunnan Province, which was historically a trading post for tea. Over time, the production and consumption of Pu-erh expanded, and it became an integral part of Chinese tea culture.
Types of Pu-erh Tea
Pu-erh tea is categorized into two main types: Raw Pu-erh (Sheng Cha) and Ripe Pu-erh (Shou Cha).
-
Raw Pu-erh (Sheng Cha): This is the traditional form of Pu-erh tea, which undergoes minimal processing. After being picked, the leaves are sun-dried and then lightly steamed to soften them before being pressed into cakes, bricks, or other shapes. Raw Pu-erh is known for its ability to age well, with its flavor profile evolving over time. It starts with a sharp, grassy taste and gradually mellows into a smoother, more complex flavor as it ages.
-
Ripe Pu-erh (Shou Cha): Developed in the 1970s, Ripe Pu-erh is created through a process of artificial fermentation, which accelerates the aging process. This method was introduced to meet the demand for a Pu-erh with a more immediate, mature flavor. Ripe Pu-erh has a distinct earthy, mellow taste and is often appreciated for its smoothness and depth.
Crafting Pu-erh Tea
The production of Pu-erh tea is a meticulous process that involves several key steps:
-
Picking: The tea leaves are handpicked from ancient tea trees in Yunnan Province. The best leaves are those that are tender and have not yet fully opened.
-
Withering: The freshly picked leaves are spread out to wither under the sun, which helps to reduce their moisture content and initiate the chemical changes that will occur during fermentation.
-
Killing Green: This step involves heating the leaves to stop the enzymatic activity that would otherwise lead to oxidation, similar to the process in green tea production.
-
Rolling: The leaves are then rolled to break down the cell walls and release the natural juices, which will contribute to the tea's flavor and aroma.
-
Fermentation: For Raw Pu-erh, this is a natural process that occurs over time as the tea ages. For Ripe Pu-erh, a controlled fermentation process is used to accelerate the aging.
-
Pressing: The fermented leaves are then pressed into various shapes, such as cakes, bricks, or tuo cha (bowls), which are traditionally wrapped in bamboo leaves.
-
Aging: Raw Pu-erh is stored and allowed to age, which can take several years or even decades. This aging process is crucial for the development of its unique flavor and aroma.
Tasting Pu-erh Tea
The art of tasting Pu-erh tea is a sensory journey that involves examining the tea's appearance, aroma, taste, and aftertaste. Here are some steps to guide you through the tasting process:
-
Preparation: Use a Yixing clay teapot or a Gaiwan for brewing. Start by warming the teapot with hot water and then discard the water.
-
Tea Leaves: Place a small amount of Pu-erh tea leaves into the teapot. A general guideline is about 5 grams of tea leaves per 100 ml of water.
-
Rinsing: Pour hot water over the tea leaves and immediately discard the water. This step, known as "rinsing the tea," helps to clean the leaves and唤醒 the tea's aroma.
-
Brewing: Pour hot water over the tea leaves again and let it steep for the desired time, starting with a shorter steeping time for the first infusion and
