UK country lost opener for beers (4)
I believe the answer is:
ales
'beers' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ales that I've seen before include "A sale of beers" , "What might be delivered by pumps" , "Types of beer" , "Alcoholic drinks" .)
