Wine provided in summer — lots (6)
I believe the answer is:
merlot
'wine' is the definition.
(I know that Merlot is a grape variety)
'in summer lots' is the wordplay.
'in' says the answer is hidden in the clue.
'MERLOT' can be found hidden inside 'summer lots'.
'provided' acts as a link.
(Other definitions for merlot that I've seen before include "Black grape variety" , "Black wine grape" , "Strange wine made from elm rot" , "Red wine grape variety" , "Kind of wine grape" .)
