Sarcastic piece in German (6)

I believe the answer is:

biting

'sarcastic' is the definition.
(similar in meaning)

'piece in german' is the wordplay.
'piece' becomes 'bit' (synonyms).
'german' becomes 'g' (abbreviation).
'bit'+'in'+'g'='BITING'

(Other definitions for biting that I've seen before include "Painful or stinging" , "Sarcastic; very cold" , "(Of wit) harsh, cruel" , "Acerbic" , "Mordant" .)

I've seen this clue in the Sydney Morning Herald.
