Tea does not come in many varieties! Instead, it’s just one plant that gives us the tea leaves – the Camellia Sinensis. Anything that does not come from this plant is not a tea but an herb! All the differences in colour and flavour among the 3 main types of teas- black, green and oolong, depend on the method of processing of the tea leaves; in case of black tea, the tea leaves are exposed to air, and are oxidised, following which, they are dried. Green teas are less processed to preserve the delicate flavour and green colour-the tea leaves are mainly steamed and sundried. Oolong tea is somewhat mid-way between black and green tea.
