British port and spirit (4)
I believe the answer is:
brio
'spirit' is the definition.
(I've seen this before)
'british port' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in BBC).
'port' becomes 'rio' (Rio de Janeiro is a port).
'b'+'rio'='BRIO'
'and' acts as a link.
(Other definitions for brio that I've seen before include "Liveliness, maybe in music" , "(Of music) spirit" , "Vigour, vivacity" , "'Liveliness, vivacity (4)'" , "'Con ..., musically with vigour (4)'" .)
