If you want to unlock the secret ending to Wine Wars: Belgaard in The Witcher 3: Blood and Wine, then you are going to need to help Liam complete the 5 tasks at the Coronata Vineyard and find the secret letter that opens up further investigation for the Wine Wars: The Deus in the Machina quest. Below, we'll share details on all five troubles, and the most important one: the guarded treasure northeast of Coronata Vineyard.
A short walk east of Plegmund's Bridge and the Belgaard Vineyard is the Coronata Vineyard, where you'll find five problems that need to be fixed, so bring your silver sword. The most important of these tasks is shown on the map, as this contains the secret letter for Wine Wars: The Deus in the Machina, but we'll go over all 5 problems regardless:
Just north of Coronata, you will find two Archespores that can be killed. Once they're dead, interact with the nest to drop a bomb into it and destroy it, which completes this problem.
Head northeast of Coronata Vineyard, as you'll find two Archespores at this location. Once they're dead, you'll find a corpse on the ground that can be looted for the Orders on Elegant Stationery. Make sure you read this letter, as it opens an investigation into Vermentino Vineyard. If you've already completed the Vermentino Vineyard's problems and obtained the Letter on Elegant Stationery, then the Wine Wars: The Deus in the Machina will start.
Southeast of Coronata Vineyard is the Abandoned Site at Forest Herbarium, and you'll find just one Archespore here. You need to kill it to complete this part of the quest. You can also find List Marked With the Seal of Liam Coronata here, but it has no importance to any mission.
At the Pittapatte River Crossing, north of Dun Tynne Crossroads, you will find two Rock Trolls that you need to kill. Once they're dead, loot the corpse by the small bridge to find the Letter to Cosmo Cyrille, which starts the Coin Doesn't Stink treasure hunt. This can be completed any time, as it's not part of the questline.
Northeast of the Trading Post, you'll find a cave to enter, with three hostile bandits inside. Kill the bandits, and you will be able to rescue Liam's Herbalist, who can be escorted back to Coronata Vineyard (or just say no, as it doesn't affect her safety or your quest).
Once you have completed all five Coronata Vineyard tasks, you should complete Vermentino Vineyard's tasks or Wine Wars: The Deus in the Machina. You should NOT return to Liam until Wine Wars: The Deus in the Machina is complete.
