A drink from Schleswig-Holstein (4)

I believe the answer is:

swig

'a drink' is the definition.
(swig is a kind of drink)

'from schleswig-holstein' is the wordplay.
'from' indicates a hidden word.
'SWIG' is hidden in the letters of 'schleswig holstein'.

(Other definitions for swig that I've seen before include "Swallow drink hurriedly" , "Large gulp from the bottle" , "Glug" , "(Take) quick drink from bottle" , "Large swallow" .)

I've seen this clue in the Evening Standard.
