Drinks causing dire disorganisation in the Civil Service (6)

I believe the answer is:

ciders

'drinks' is the definition.
(cider is a kind of drink)

'dire disorganisation in the civil service' is the wordplay.
'disorganisation' is an anagram indicator.
'in' indicates putting letters inside.
'the civil service' becomes 'CS' (abbreviation).
'dire' is an anagram of 'ider'.
'ider' going into 'cs' is 'CIDERS'.

'causing' is the link.

I've seen this clue in the Evening Standard.
