Temps beer brewed for thirty days (9)
I believe the answer is:
september
'thirty days' is the definition.
'temps beer brewed' is the wordplay.
'brewed' indicates anagramming the letters.
'temps'+'beer'='tempsbeer'
'tempsbeer' anagrammed gives 'SEPTEMBER'.
'for' is the link.
(Other definitions for september that I've seen before include "- Song (Kurt Weill)" , "Tempers be strangely raised at this time" , "Last month" , "The longest month?" , "It follows 3" .)
