Stages of "Wine Wars: The Deus in the Machina" quest
1. Find the place mentioned in the letter.
From the start, both Matilda and Liam insisted the problems at their vineyards had not appeared out of thin air. Naturally, they accused one another of foul play. Geralt suspected there was more to the matter, and yet again his intuition proved true. While solving the problems at the vineyards, he had happened on some notes. These suggested someone had intentionally planted archespores amidst the vines at both estates. The witcher had also found a key to the shelter where saplings of the beastly plants had been stored.
2. Search the warehouse using your Witcher Senses.
2.1. Defeat the archespore.
Kill the Archespore (42).

4. Quest completed.
What Geralt had learned shed new light on the dispute between Liam and Matilda. It seemed Count Crespi had intentionally incited the quarrel between them. They decided to do him one better. Liam and Matilda settled their differences and formed a consortium.
