Article promoted in drinks range? (4)
I believe the answer is:
alps
'range?' is the definition.
(Alps is an example)
'article promoted in drinks' is the wordplay.
'article' becomes 'a' (indefinite article).
'promoted' says the letters should be written in reverse (going up, in a down clue).
'in drinks' becomes 'spl' (I can't justify this - if you can you should believe this answer much more).
'spl' written backwards gives 'lps'.
'a'+'lps'='ALPS'
(Other definitions for alps that I've seen before include "high areas" , "Pals put on the mountains" , "Slap (anag.)" , "high points" , "Mountain pastures" .)
