From light to dark and from flavoured to milky, these teas are a must for any discerning tea lover. Just watch those lovely leaves unfurl as you brew. Taiwan is famous for their oolong teas (Formosa) but it is also produced in China, Thailand and even Darjeeling. Oolong can be quite green in colour or more oxidised and is either rolled or butterfly in style. It is well known for its ability to cope with being steeped several times and brings a different note each time it is brewed.
