Principality ignoring capital drinks (4)
I believe the answer is:
ales
'drinks' is the definition.
(ale is a kind of drink)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ales that I've seen before include "What might be delivered by pumps" , "Alcoholic drinks" , "Types of beer" , "A sale of beers" .)
