Unexpectedly dire new drink (3,4)
I believe the answer is:
red wine
'drink' is the definition.
(red wine is a kind of drink)
'unexpectedly dire new' is the wordplay.
'unexpectedly' is an anagram indicator.
'dire'+'new'='direnew'
'direnew' is an anagram of 'RED WINE'.
(Other definitions for red wine that I've seen before include "Merlot or Malbec, say" , "Tent, say" , "Eg, claret" , "Such as Shiraz or Merlot" , "Vin rouge, like claret" .)
