Below summit dash up for drink (5,3)
I believe the answer is:
brown ale
'drink' is the definition.
(I've seen this before)
'below summit dash up' is the wordplay.
I cannot really see how this works, but
'summit' could be 'brow' (brow is a kind of summit) and 'brow' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for brown ale that I've seen before include "Dark, malty beer" , "Dark, mild beer" , "Type of beer" , "Noble war (anag) - drink" , "bottled beer" .)
