Order fresh, crisp beer (9)
I believe the answer is:
prescribe
'order' is the definition.
(synonyms)
'fresh crisp beer' is the wordplay.
'fresh' indicates anagramming the letters (a fresh re-ordering of the letters).
'crisp'+'beer'='crispbeer'
'crispbeer' is an anagram of 'PRESCRIBE'.
(Other definitions for prescribe that I've seen before include "Advise use of (medicine)" , "Lay" , "Order use of (medicine or other treatment)" , "as doctor may order" , "Recommend as beneficial" .)
