Aromatic bark, used in a liqueur (9)

I believe the answer is:

angostura

(Other definitions for angostura that I've seen before include "Bitters for 13" , "An aromatic bark, made bitter tonic" , "Bitter bark of a South American tree, used in liqueurs" , "bitter substance" , "Bitter stuff for Argonauts" .)

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