Wine and port Jane half finished (5)
I believe the answer is:
rioja
'wine' is the definition.
(I know that Rioja is a type of red)
'port jane half finished' is the wordplay.
'port' becomes 'rio' (Rio de Janeiro is a port).
'half finished' suggests halving the letters.
'jane' with half the letters taken is 'ja'.
'rio'+'ja'='RIOJA'
'and' is the link.
(Other definitions for rioja that I've seen before include "kind of red" , "Spanish wine type" , "Wine from northern Spain" , "it comes from grapevine" , "Popular Spanish wine" .)
