Wind caused by last bit of fruit drink (5)
I believe the answer is:
twine
'wind' is the definition.
(I've seen this before)
'last bit of fruit drink' is the wordplay.
'last bit of' suggests the final letters.
'drink' becomes 'wine' (wining is a kind of drinking).
The last letter of 'fruit' is 't'.
't'+'wine'='TWINE'
'caused by' acts as a link.
(Other definitions for twine that I've seen before include "Interweave" , "wind" , "Knot" , "Tough string" , "Stout string" .)
