Factory tea-tasters will taste the finished make to ensure that no mistakes have been made during the manufacture or that the tea has not been contaminated by anything within the factory. Samples of the make are sent to selling brokers worldwide.

Such tea is a large leaf or Orthodox tea and is best drunk without milk, as it has a pale, bright liquor with a very delicate flavour. Tea Tea is sold in a variety of ways. Tea may be sold at auction in countries of origin.
