All are excited drinking English beer (4,3)
I believe the answer is:
real ale
'beer' is the definition.
(type of beer)
'all are excited drinking english' is the wordplay.
'excited' is an anagram indicator.
'drinking' means one lot of letters goes inside another.
'english' becomes 'e' (abbreviation).
'all'+'are'='allare'
'allare' with letters rearranged gives 'ralale'.
'ralale' placed around 'e' is 'REAL ALE'.
(Other definitions for real ale that I've seen before include "Beer fermented in cask, served without carbon dioxide" , "Objective of campaign" , "Traditional drink" , "Pub drink" , "Bitter, possibly" .)
