Drinks spilt: PE ruined! (7)
I believe the answer is:
tipples
'drinks' is the definition.
(tipple is a kind of drink)
'spilt pe ruined' is the wordplay.
'ruined' indicates an anagram.
'spilt'+'pe'='spiltpe'
'spiltpe' with letters rearranged gives 'TIPPLES'.
(Other definitions for tipples that I've seen before include "Drinks alcohol regularly" , "Drinks moderately" , "Is in the habit of drinking alcohol" .)
