Artisan beer we drink extra warm - bottoms up! (5)
I believe the answer is:
maker
'artisan' is the definition.
(thesaurus)
'beer we drink extra warm bottoms up' is the wordplay.
'bottoms' indicates one should take the final letters (I've seen 'bottom' mean this).
'up' says the letters should be written backwards (in down clue: letters go upwards).
The final letters of 'beer we drink extra warm' are 'rekam'.
'rekam' reversed gives 'MAKER'.
(Other definitions for maker that I've seen before include "God Almighty" , "Creator" , "Producer" , "One who creates or constructs" , "Fabricator; poet (arch.)" .)
