Some missions shine brighter than others, particularly when navigating complex multi-stage quests like "In Vino Veritas" in Kingdom Come: Deliverance 2. This layered adventure combines investigation with social engineering, complete with an embedded side mission.
Speak with Casper and Havel

Casper Rudolf initiates this quest near his beverage cart in Kuttenberg's eastern district. Approaching from the east gate leads directly to his location. His fascination with monastic winemaking secrets unfolds through multiple dialogue branches. Exhaust all conversation options to uncover two critical paths: obtaining a book from Adleta or impressing innkeeper Havel directly.
For the Adleta route, visit Kuttenberg's southeastern inner wall garden during daylight hours. Bring five Marigolds as either a bribe or peace offering. Navigate her protective brother Hugo carefully through dialogue choices. Successfully retrieving the book requires either persuasion skills or floral tribute.
The alternative approach focuses on charming Havel at his Kuttenberg tavern. Prepare by:
- Boosting alcohol tolerance
- Equipping Charisma-enhancing attire (minimum 18)
- Selecting specific dialogue responses about German wines and ingredients
Uncovering the Secret Ingredient

The investigation leads north to Kuttenberg's vineyards, where initiating the optional "Under the Straw Hat" subquest provides legitimate access. Locate Jerome near the main building before infiltrating the storage area. Lockpicking reveals the prized Sulphur Wicks - the monks' winemaking secret.

Opportunistic players can also gather five valuable vine seedlings from the rear garden. Those completing the optional vineyard tasks earn additional compensation from Jerome before returning to Casper with the crucial ingredients.
Finalizing this complex quest opens new gameplay opportunities, from dice tournaments to badge collecting across the richly detailed medieval landscape.
