Cocktail made with brandy, as cider awful (7)
I believe the answer is:
sidecar
'cocktail made with brandy' is the definition.
'as cider awful' is the wordplay.
'awful' is an anagram indicator.
'as'+'cider'='ascider'
'ascider' anagrammed gives 'SIDECAR'.
(Other definitions for sidecar that I've seen before include "Attachment on motorcycle to carry passenger" , "In which a passenger may be taken" , "Motorcycle add-on" , "Motorbike passenger attachment" , "that's suitable for a non-driver" .)
