Also called turquoise tea, this type of tea is considered to be semi-oxidized: after being collected the material is usually dried (withered), oxidized to a certain extent and then shaped. Oolongs have the largest range of flavours compared to other tea types. This tea is produced in Fujian, Guangdong and Taiwan. Oolongs can be divided into light or dark and ball shaped or twisted. They are valued for their nuanced flavour and exquisite aroma.
