Special case of Lambrusco barman presented as something else (8)
I believe the answer is:
abnormal
'as something else' is the definition.
I can't tell whether this defines the answer.
'special case of lambrusco barman' is the wordplay.
'special' is an anagram indicator.
'case of' suggests removing the centre (like emptying a case).
'lambrusco' with its middle taken out is 'lo'.
'lo'+'barman'='lobarman'
'lobarman' with letters rearranged gives 'ABNORMAL'.
'presented' acts as a link.
Can you help me to learn more?
(Other definitions for abnormal that I've seen before include "'Aberrant, atypical (8)'" , "Deviating from the standard" , "Anomalous" , "Odd" , "Different to what is ordinary or expected" .)
