A Few Things to Know
Clear answers to common questions, so you can explore this selection with ease.
What is black tea?
Black tea is a type of tea made from the leaves of the Camellia sinensis plant. Unlike green tea or white tea, black tea leaves undergo full oxidation after harvesting, a process that gives black tea its deep amber color and bold, rounded flavor.
This oxidation develops complex aromas that can range from malty and woody to fruity or slightly sweet depending on the origin and processing method. Today, black tea is one of the most widely consumed types of tea in the world.
If you're curious about how different teas compare, you can explore the difference between green, white, and black tea.
Where does black tea come from?
Although tea originated in China thousands of years ago, black tea as it is known today developed later through specific processing techniques. Today, black tea is produced in many regions including China, India, Sri Lanka, Kenya and Nepal.
Each region produces black tea with distinctive flavor profiles shaped by climate, altitude, soil composition and traditional methods of cultivation and processing.
What makes black tea different from other teas?
Black tea differs from other teas mainly because of the oxidation process applied to the leaves after harvest. While green tea is heated quickly to stop oxidation and white tea is only lightly processed, black tea leaves are allowed to oxidize fully.
This transformation darkens the leaves and allows black tea to develop a fuller body, deeper aromas and a richer color in the cup.

What are the main varieties of black tea?
Black tea varieties are often identified by their region of origin. Chinese black tea styles such as Yunnan or Keemun are known for their smooth and complex character.
Indian black tea includes Assam, which is strong and malty, and Darjeeling, which is lighter and more floral. Ceylon black tea from Sri Lanka is typically bright and lively, often showing subtle citrus notes.
What flavors can black tea have?
Black tea can present a wide range of flavor profiles depending on its origin and processing method. Some black tea varieties display malty or honeyed notes, while others reveal fruity, floral, woody or gently spicy aromas.
Certain styles such as Lapsang Souchong develop distinctive smoky characteristics, making black tea one of the most diverse tea categories.
What are the benefits of black tea?
