What is Black Tea?

Black tea, known as "red tea" in China, is one of the most consumed teas in the world. It is made from the leaves of the Camellia sinensis plant, which are wilted, rolled, oxidized and dried. This process gives the tea its characteristic dark color and rich, robust flavor.

Unlike green, white and oolong teas, which undergo less oxidation, black tea is completely oxidized. This oxidation creates the complex aromas and flavors that distinguish black tea from other teas.

Black tea contains more caffeine than other teas, making it a popular choice for those seeking an energy boost. It is often served with milk and sugar, especially in Western cultures, but can also be enjoyed neat.

The history of black tea: origin and distribution

The origins of black tea can be traced to ancient China, where it was first produced during the Ming Dynasty ( 1368-1644 ). In China, black tea is known as "red tea" because of the red color of the brewed liquid.

Ming Dynasty in China

The production and consumption of black tea gradually spread to other parts of Asia, including India, where it became an integral part of tea culture. The British played a crucial role in spreading black tea west, and it quickly became a staple in countries such as the United Kingdom and the United States.

In India, the introduction of black tea led to the development of famous teas such as Assam, Darjeeling and Nilgiri. In Sri Lanka, formerly known as Ceylon, black tea became a major export and led to the creation of the famous Ceylon tea.

The history of black tea is one of innovation, colonization and cultural exchange. It has profoundly influenced the way people around the world experience and enjoy tea.

How is black tea made?

The production of black tea is a careful and complex process that determines the unique taste and aroma of the tea. Here are the most important steps:

  1. Wilting : The freshly picked tea leaves are spread out to wilt, which causes them to lose their moisture and become more pliable.
  2. Rolling : The wilted leaves are rolled to break the cell walls and release the enzymes and oils that contribute to the tea's flavor.
  3. Oxidizing : The rolled leaves are exposed to air, causing a chemical reaction that darkens the leaves and develops flavor.
  4. Drying : The oxidized leaves are dried to stop the oxidation process and preserve the tea.
  5. Sorting : The dried leaves are sorted by size and quality, and any stems or unwanted particles are removed.
  6. Packaging : The graded tea is packaged for distribution and sale.

These steps may vary depending on the specific type of black tea and the traditions of the region where it is produced.
