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 the' means one lot of letters goes inside another.
'civil service' becomes 'CS' (abbreviation).
'dire' with letters rearranged gives 'ider'.
'ider' inserted into 'cs' is 'CIDERS'.

'causing' acts as a link.

I've seen this clue in the Evening Standard.
