Hot teas brewed well (6)
I believe the answer is:
steamy
'hot' is the definition.
(I've seen this before)
'teas brewed well' is the wordplay.
'brewed' indicates anagramming the letters.
'well' becomes 'my' (I've seen this in other clues).
'teas' anagrammed gives 'stea'.
'stea'+'my'='STEAMY'
(Other definitions for steamy that I've seen before include "Erotic; like vapour" , "My seat (anag.)" , "Erotic, sexy" , "Passionate" , "Full of vapour; erotic (book)" .)
