What is green tea?

Green tea is one of the most original types of tea – made directly from the tea plant (Camellia sinensis), but without fermentation . The leaves are briefly heated (steamed or roasted) after harvesting to stop oxidation.

This keeps the tea fresh, vibrant, and rich in secondary plant compounds . In terms of taste, green tea ranges from grassy to nutty, fresh to slightly sweet.
