Old opera company record unknown for wine producers’ scholarship? (8)
I believe the answer is:
oenology
'wine producers' scholarship?' is the definition.
The definition suggests a singular noun which matches the answer.
'old opera company record unknown' is the wordplay.
'old' becomes 'o' (abbreviation as in OT - Old Testament).
'opera company' becomes 'ENO' (English National Opera).
'record' becomes 'log' (log is a kind of record).
'unknown' becomes 'y' (algebra).
'o'+'eno'+'log'+'y'='OENOLOGY'
'for' is the link.
Can you help me to learn more?
(Other definitions for oenology that I've seen before include "The science of wines" , "Wine knowledge" , "The art of wine making" , "The study of wine making" .)
