Unsophisticated type with hundred to invest in shockingly sour wine (9)
I believe the answer is:
lambrusco
'wine' is the definition.
(I've seen this before)
'unsophisticated type with hundred to invest in shockingly sour' is the wordplay.
'unsophisticated type' becomes 'lamb' (I can't explain this - if you can you should believe this answer much more).
'with' means one lot of letters go next to another.
'hundred' becomes 'c' (Roman numeral).
'to invest in' is an insertion indicator.
'shockingly' is an anagram indicator.
'sour' with letters rearranged gives 'ruso'.
'c' put within 'ruso' is 'rusco'.
'lamb'+'rusco'='LAMBRUSCO'
Can you help me to learn more?
(Other definitions for lambrusco that I've seen before include "Type of Italian wine" , "Sparkling Italian wine" , "Medium sweet, semi-sparkling Italian red or white wine" .)
