Savage into booze creates puzzle (8)
I believe the answer is:
bewilder
'puzzle' is the definition.
(I know that puzzle can be written as bewilder)
'savage into booze' is the wordplay.
'savage' becomes 'wild' (similar in meaning).
'into' is an insertion indicator.
'booze' becomes 'beer'.
'wild' placed inside 'beer' is 'BEWILDER'.
'creates' is the link.
(Other definitions for bewilder that I've seen before include "fox" , "Confuse utterly" , "Perplex the wild beer" , "Flummox, confuse" , "Confuse totally" .)
