This is a daily epic mission in Besieged Tortuga.
- Bottle of Killdevil (3)
- Bottle of "Tortoise Tail" Wine (1)
Fight your way to the Empty Gibbet bar, and defeat the enemies inside (at which point a barrel of wine will become clickable).
Bottles of Killdevil can be looted from barrels near the tavern (one additional barrel can also be found not far from The Pit).
This mission can be done at the same time with the Fisto Inferno.
