A 'way out' beverage? (5)
I believe the answer is:
stout
'beverage?' is the definition.
(stout is a kind of beverage)
'a way out' is the wordplay.
'a way' becomes 'st' (abbreviation for street).
'st'+'out'='STOUT'
(Other definitions for stout that I've seen before include "Corpulent" , "Fat; dependable" , "drinks?" , "tipple" , "Overweight; porter" .)
