Has sampled some tea (5)
I believe the answer is:
assam
'tea' is the definition.
(I've seen this before)
'has sampled some' is the wordplay.
'some' indicates the answer is hidden within the clue.
'ASSAM' is hidden within 'has sampled'.
(Other definitions for assam that I've seen before include "Indian state known for tea growing" , "Sort of tea" , "Indian province" , "State of NE India" , "I'll provide lots of tea" .)
