Green Tea vs. Black Tea: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 21, 2023
Green tea is made from unoxidized leaves and has lighter flavor; black tea undergoes full oxidation, yielding a dark color and robust taste.

Key Differences

Green tea and black tea both originate from the same plant, Camellia sinensis. However, the methods of processing these teas differ, resulting in distinctive flavors, colors, and health benefits. Green tea, known for its lighter hue and taste, undergoes minimal processing. This ensures that the tea retains more of its natural antioxidants and catechins.
On the other hand, black tea undergoes a process known as oxidation, which exposes the tea leaves to air, leading to browning, much like a sliced apple turns brown. This oxidation imparts black tea with its deep color and rich flavor. Compared to green tea, black tea usually contains higher caffeine content and different types of antioxidants due to the longer oxidation process.
One of the notable characteristics of green tea is its subtle and fresh flavor profile, often described with vegetal or grassy notes. This is a stark contrast to black tea, which has a more robust and bold taste, with flavors ranging from fruity to malty, depending on its type and processing. Many people drink green tea for its purported health benefits, believing it to be rich in antioxidants that can combat free radicals in the body.
Contrarily, black tea, with its hearty flavor, is often enjoyed with additives like milk, sugar, or spices in many cultures. While green tea might be praised for its health benefits, black tea also offers a range of health advantages due to its unique set of antioxidants. Ultimately, the preference between green tea and black tea boils down to individual taste profiles and health considerations.
