Opt cryptically for wine (5)
I believe the answer is:
pinot
'for wine' is the definition.
(eg pinot noir)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pinot that I've seen before include "Black or white grape variety" , "Variety of wine grape" , "Wine-making grape" , "drink" , "Red or white ingredient" .)
