She makes a brew of ale hot! (4)
I believe the answer is:
leah
'she' is the definition.
'a brew of ale hot' is the wordplay.
'a brew of' indicates an anagram (I've seen this in other clues).
'hot' becomes 'h' (abbreviation eg on taps).
'ale' is an anagram of 'lea'.
'lea'+'h'='LEAH'
'makes' acts as a link.
(Other definitions for leah that I've seen before include "Heal (anag) - girl" , "She married Jacob" , "Hale (anag) - wife of Jacob" , "First wife of Jacob" , "Jacobs first wife (Gen.29)" .)
