Be quiet, be human and, finally, enjoy this wine (6)
I believe the answer is:
sherry
'this wine' is the definition.
(sherry is a kind of wine)
'be quiet be human and finally enjoy' is the wordplay.
'be quiet' becomes 'sh' (both are said to tell someone to stop speaking).
'be human' becomes 'err' (to err is human, to forgive divine).
'and' means one lot of letters go next to another.
'finally' suggests the final letters.
The final letter of 'enjoy' is 'y'.
'sh'+'err'+'y'='SHERRY'
(Other definitions for sherry that I've seen before include "Wine from the Jerez region of Spain" , "Alcoholic appetiser associated with Jerez" , "Alcoholic drink" , "Christmas drink?" , "Fortified wine originally from Spain" .)
