Beer Mac brewed is welcome (7)
I believe the answer is:
embrace
'is welcome' is the definition.
(I've seen this in another clue)
'beer mac brewed' is the wordplay.
'brewed' is an anagram indicator.
'beer'+'mac'='beermac'
'beermac' is an anagram of 'EMBRACE'.
(Other definitions for embrace that I've seen before include "Willingly accept" , "Hug; adopt" , "Cuddle" , "Hug, put arms around" , "Hold affectionately" .)
