Spill from a keg ale, upset (7)

Ross

I believe the answer is:

leakage

'spill' is the definition.
(thesaurus)

'a keg ale upset' is the wordplay.
'upset' is an anagram indicator.
'a'+'keg'+'ale'='akegale'
'akegale' is an anagram of 'LEAKAGE'.

'from' is the link.

(Other definitions for leakage that I've seen before include "Gradual escape" , "Liquid lost" , "Discharge of fluid through a small gap" , "Percolation" , "Escape of liquid/gas" .)

I've seen this clue in The Times.
