More reasonable about bringing in college’s white wine (8)
I believe the answer is:
sancerre
'white wine' is the definition.
'Sancerre' can be an answer for 'wine' (I've seen this before). I am not sure about the 'white' bit.
'more reasonable about bringing in college's' is the wordplay.
'more reasonable' becomes 'saner' ('sane' can be similar in meaning to 'reasonable').
'about' becomes 're' ('re' means regarding or about).
'bringing in' means one lot of letters goes inside another.
'college' becomes 'c'.
'saner'+'re'='sanerre'
'sanerre' going around 'c' is 'SANCERRE'.
Can you help me to learn more?
(Other definitions for sancerre that I've seen before include "Type of French white wine" , "Light French white wine" .)
