The vessel a drunken sot takes up (5)

I believe the answer is:

stoup

'the vessel' is the definition.
(stoup is a kind of vessel)

'a drunken sot takes up' is the wordplay.
'a drunken' is an anagram indicator.
'takes' means one lot of letters go next to another.
'sot' anagrammed gives 'sto'.
'sto'+'up'='STOUP'

(Another definition for stoup that I've seen is " Basin for holy water".)

I've seen this clue in the Evening Standard.
