Black tea is a tea style made from the leaves of Camellia sinensis that undergo substantial oxidation during processing. The process changes the colour, aroma and flavour of the leaf and produces the deep amber, coppery or reddish-brown liquor commonly associated with it.
It is not one single flavour. Assam CTC, Assam orthodox, Darjeeling, Chinese black teas and Sri Lankan teas can all be very different while belonging to the same broad category.
What Is Black Tea?
It is produced by allowing tea leaves to undergo significant oxidation after the leaf has been plucked and prepared.
The exact manufacturing sequence depends on the style. Withering reduces moisture, rolling or other forms of leaf disruption help initiate chemical changes, oxidation develops the desired character, and drying stabilises the finished tea.
The result is a darker tea with a broad range of possible aromas and flavours.
How Is Black Tea Made?
Although production differs between orthodox and CTC styles, several stages are common.
Fresh leaves may first be withered. They are then processed to prepare the leaf for oxidation. After oxidation reaches the desired point, the tea is dried.
Orthodox processing generally retains more recognisable leaf form. CTC means crush, tear and curl and produces smaller, more uniform particles that extract quickly.
What Does Black Tea Taste Like?
There is no single black tea flavour.
Depending on origin and production, black tea can be malty, brisk, fruity, floral, woody, smoky, sweet or earthy. Some teas are light and aromatic, while others are full-bodied and powerful.
Brewing also changes perception. A strong brew can make a tea feel more bitter or astringent than the same tea brewed more gently.
Black Tea vs Green Tea
The major difference is processing.
Green tea is produced to minimise oxidation, while black tea undergoes substantial oxidation.
This changes the chemistry and sensory character of the finished leaf. Green tea is often associated with fresh, vegetal or delicate notes, while black tea can show deeper, maltier and more rounded characteristics.
These are broad tendencies, not rules.
Assam Black Tea
Assam is one of the world’s most important black tea-growing regions and is particularly known for teas with body, briskness and malty character.
Assam produces both CTC and orthodox teas. CTC is widely used in blends and milk tea because it extracts quickly and produces a strong cup. Orthodox Assam can retain more leaf structure and can offer a more layered tasting experience.
The region therefore represents more than one style of black tea.
How Should You Brew Black Tea?
The best method depends on the tea.
<br />For a robust Assam CTC intended for milk, a hot, relatively strong infusion may work well. For a delicate orthodox black tea, a more moderate approach can preserve aroma.
<br />If the cup is bitter or excessively drying, reduce steeping time before adding more sugar. Brewing is part of the tea’s flavour.
Why Black Tea Is So Widely Consumed
It works across many drinking traditions. It can be served plain, with milk, with sugar, iced or blended with spices and other flavouring ingredients.
Its broad range of styles makes it suitable for breakfast, afternoon tea, hospitality and everyday chai.
This versatility is one reason black tea remains one of the most familiar tea categories in the world.
Final Thought
It is a broad family, not a single taste. Its character is shaped by origin, cultivar, harvest, processing and brewing.
Assam shows this particularly well: CTC and orthodox teas can come from the same region yet create very different experiences.
Understanding it begins with looking beyond colour and asking how the leaf was grown, processed and brewed.
Frequently Asked Questions
What is black tea?
Black tea is tea made from Camellia sinensis leaves that undergo substantial oxidation.
Is black tea stronger than green tea?
Not automatically. Strength depends on tea material, brewing and concentration.
What is Assam black tea known for?
Assam black teas are often associated with body, briskness and malty character.
What is the difference between CTC and orthodox black tea?
CTC mechanically crushes, tears and curls the leaf into small particles, while orthodox processing generally preserves more leaf form.
