Beer from Wales (3)
I believe the answer is:
ale
'beer' is the definition.
(type of beer)
'from wales' is the wordplay.
'from' indicates a hidden word.
'ALE' is hidden in the letters of 'wales'.
(Other definitions for ale that I've seen before include "Booze" , "Type of beer" , "Similar to beer" , "Intoxicating drink" , "brewing?" .)
