Quite intoxicated by the French spirit (7)
I believe the answer is:
tequila
'spirit' is the definition.
(alcoholic spirit)
'quite intoxicated by the french' is the wordplay.
'intoxicated' is an anagram indicator.
'by' is a charade indicator (letters next to each other).
'the french' becomes 'la' (one of the French words for 'the').
'quite' with letters rearranged gives 'tequi'.
'tequi'+'la'='TEQUILA'
(Other definitions for tequila that I've seen before include "Liquor made from the agave plant" , "Mexican liquor made from agave" , "Cocktail -- 1988 American crime film -- equaliser units (anag)" , "Quit ale for Mexican spirit" , "Mexican alcoholic drink" .)
