Black tea variety (5)
I believe the answer is:
pekoe
'black tea variety' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pekoe that I've seen before include "Thin mark; run naked" , "Type of black tea" , "High-quality black tea" , "Superior grade of black tea" , "Scented black tea" .)
