Some current beer bottles for Scotch (5,3)
I believe the answer is:
stamp out
'scotch' is the definition.
(I've seen this before)
'some current beer bottles' is the wordplay.
'some current' becomes 'amp' (electricity).
'beer' becomes 'stout' (I've seen this before).
'bottles' means one lot of letters goes inside another ('bottle' can mean to contain).
'amp' put inside 'stout' is 'STAMP OUT'.
'for' is the link.
(Other definitions for stamp out that I've seen before include "A stout MP (anag.)" , "Suppress with heavy foot" , "Completely dispose of" , "Eradicate - as with heavy foot (5,3)" , "Scotch" .)
