Drink from mid-Wales (3)
I believe the answer is:
ale
'drink' is the definition.
(type of beer)
'from mid-wales' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ALE' is hidden in the letters of 'mid wales'.
(Other definitions for ale that I've seen before include "English beer in sales" , "Brewery product" , "English beer, mild or bitter" , "Similar to beer" , "Alcoholic beverage" .)
