Artist takes one old judge for a wine (5)
I believe the answer is:
rioja
'wine' is the definition.
(Rioja is an example)
'artist takes one old judge' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'takes' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'old' becomes 'o' (abbreviation as in OT - Old Testament).
'judge' becomes 'J' (abbreviation for judge).
'i'+'o'+'j'='ioj'
'ra' going around 'ioj' is 'RIOJA'.
'for a' is the link.
(Other definitions for rioja that I've seen before include "Spanish red wine" , "kind of red" , "Open space (ancient Greek)" , "Dry red wine from Spain" , "Spanish wine type" .)
