Summer lottery prize? Some wine? (6)
I believe the answer is:
merlot
'wine?' is the definition.
(I know that Merlot is a type of red wine)
'summer lottery prize? some' is the wordplay.
'some' says the answer is hidden in the clue.
'MERLOT' is hidden in the letters of 'summer lottery prize'.
(Other definitions for merlot that I've seen before include "French variety of grape" , "Strange wine made from elm rot" , "Wine made from bad elm rot" , "Grape makes elm rot" , "Wine-producing black grape" .)
