It's natural to brew tea at the tavern (6)
I believe the answer is:
innate
'it's natural to' is the definition.
(thesaurus)
'brew tea at the tavern' is the wordplay.
'brew' is an anagram indicator.
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the tavern' becomes 'inn' (I've seen this before).
'tea' with letters rearranged gives 'ate'.
'ate' after 'inn' is 'INNATE'.
(Other definitions for innate that I've seen before include "quite natural" , "Inborn in neat way" , "Inborn, natural to (6)" , "'Inborn, not learned (6)'" , "instinctive ..." .)
