Time for Left and Right to drink beer (5)
I believe the answer is:
lager
'beer' is the definition.
(lager is a kind of beer)
'time for left and right to drink' is the wordplay.
'time for' becomes 'age' (I've seen this in other clues).
'left' becomes 'l' (common abbreviation).
'and' means one lot of letters go next to another.
'right' becomes 'r' (common abbreviation).
'to drink' indicates putting letters inside.
'l'+'r'='lr'
'age' inserted within 'lr' is 'LAGER'.
(Other definitions for lager that I've seen before include "A brew" , "Effervescent beer" , "Light beer needed" , "African camp" , "drink in the bar?" .)
