Gran is getting sozzled with a wine (7)
I believe the answer is:
sangria
'wine' is the definition.
(I've seen this before)
'gran is getting sozzled with a' is the wordplay.
'getting sozzled with' indicates an anagram (sozzled can mean drunk and therefore disordered).
'gran'+'is'='granis'
'granis' mixed up with 'a' gives 'SANGRIA'.
(Other definitions for sangria that I've seen before include "A party drink" , "Spanish drink based on red wine" , "Spanish drink of red wine and spices" , "Spicy Spanish wine drink" , "Spanish sweetened wine drink" .)
