French teacher produced wine, around one (12)

'french teacher' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.

'produced wine around one' is the wordplay.
I cannot really understand how this works, but
'produced' could be 'made' ('make' can be a synonym of 'produce') and 'made' is found within the answer.
'wine' could be 'm' (I have seen 'French wine ' mean 'm' so perhaps 'wine' could also mean 'm') and 'm' is present in the answer.
'around' could be 'o' (a round letter) and 'o' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
The remaining letters 'selle' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
