Drink Strongbow in extra-large bottles (4)
I believe the answer is:
wine
'drink' is the definition.
(wine is an alcoholic drink)
'strongbow in extra-large bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'WINE' is hidden in the letters of 'strongbow in extra large'.
(Other definitions for wine that I've seen before include "Vino" , "Frascati, perhaps" , "Accompaniment for women and song?" , "Plonk" , "Alcoholic grape juice" .)
