After the tea has been processed, it is graded by leaf size, appearance and quality. The following are abbreviations commonly found in TeaSource. These describe the physical leaf itself, not the taste.
Orange Pekoe (OP) - This tea usually does not contain any tip. Compared to an FOP tea, the leaves of an OP tea have been plucked when the bud opens into a leaf producing a longer leaf.
Try: Thiasola OP
Flowery Orange Pekoe (FOP) - A tea that is made up of young buds and first leaves. It also contains a well balanced amount of tip (the end pieces of the bud).
Try: Yunnan FOP
Tippy Golden Flowery Orange Pekoe (TGFOP) - This tea is the same as a FOP tea but with more golden tips.
