Yellow tea is one of the six main classes of Chinese teas. It's production is similar to green teas, with an additional process called 'Wo Huang' - a deliberate prolonging of a green tea sitting stage to turn the leaves into a deeper yellow colour. Yellow tea has a different taste from both the green or white teas. It is relatively unknown to even experienced tea drinkers and sometimes confused with old green teas. Yellow tea brew has a yellow tone, fragrant, slightly sweet and refreshing taste - key characters to differentiate from un-fresh green teas.
