In open hole I discovered wine lover (9)

I believe the answer is:

oenophile

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

'wine lover' is the definition.
(I've seen this before)

'in open hole i' is the wordplay.
'open hole i' can be anagrammed to 'OENOPHILE'.
Though, I'm unsure how this is indicated.

'discovered' acts as a link.

Can you help me to learn more?

(Other definitions for oenophile that I've seen before include "Drink lover" , "grape nut" , "Wine-lover" , "Wine buff" , "Connoisseur of wine" .)

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