A Croaking Cryptid Softlocked?

For this hidden discovery in Fruma. When you first meet the NPC at the Hut at -2091, -1047, do her little errand and get rewarded, you get the "Auburn Absinthe". However, the stupid me threw the bottle away, and now I can't get a second bottle of it to finish the hidden discovery.

Is there anyway to fix this?

 

I mean it might be possible if you level up another class and do it again but apart from that idk
