Green and black tea come from the same plant, Camellia sinensis — the real difference lies in processing, not the source. Green tea leaves are dried and quickly heated right after picking, which stops oxidation and preserves the green color, fresh taste, and more of the leaf's natural antioxidants.
Black tea leaves, on the other hand, are left to fully oxidize before drying. This process darkens them and develops deeper, bolder flavors — from the malty notes of a Royal Black Tea to the citrusy freshness of an Earl Grey+.
As for caffeine, the difference is smaller than most people think: both contain natural caffeine, with the amount depending more on steeping time than tea type. If you prefer a light, refreshing taste, go for a green tea like Himalayan Green Tea. If you want something bold for the morning, black tea is the natural choice.
