It's the place of vines to exclude mountain in Thessaly (7)

I believe the answer is:

barossa

I'm a little stuck... Click here to teach me more about this clue!

'it's the place of vines' is the definition.
I know nothing about this answer so I can't tell whether this works.

'exclude mountain in thessaly' is the wordplay.
'exclude' becomes 'bar' (synonyms).
'mountain in thessaly' becomes 'ossa' (I've seen this before).
'bar'+'ossa'='BAROSSA'

'to' acts as a link.

Can you help me to learn more?

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