How to Complete In Vino Veritas in Kingdom Come Deliverance 2

Some side quests are more enjoyable than others, while some prove more confusing or frustrating. Completing "In Vino Veritas" in Kingdom Come: Deliverance 2 involves numerous small steps and even a side quest within a side quest. Let's break it down.

Speak with Casper and Havel

Begin "In Vino Veritas" by speaking with Casper Rudolf, located at his drink cart on the east side of Kuttenberg City (easily found by proceeding straight from the east gate). He seeks the secret to the monks' superior wine. Exhaust all dialogue options to learn about Havel and the book he entrusted to Adleta. This informs your approach to impressing Havel.

To obtain the book from Adleta, visit her garden in the southeast corner of Kuttenberg's inner walls during the morning or afternoon. Gather five marigolds beforehand. Either find her before her brother, Hugo, arrives, or speak with Hugo to gain permission to talk to her. Remain kind to Adleta, explaining your need for the book. You can attempt a skill check to obtain it directly, or gift her the marigolds. Once acquired, read the book from your inventory. Note: Obtaining the book is optional.

Alternatively, proceed directly to Havel at his inn in Kuttenberg City. Boost your Charisma to at least 18 (consider your attire). Engage Havel, selecting the following dialogue options: Germany, Let's do it, That's a very fine gift, Steinberger, It's missing ginger. This impresses Havel, revealing the monastery's secret ingredient. Report back to Casper.

Find the Monastery’s Secret Ingredient

Travel to the vineyard north of Kuttenberg. Initiate the "Under the Straw Hat" side quest by speaking with the recruiter (completing this quest is optional, but starting it allows free movement within the vineyard). Locate Jerome on a bench near the main building.

Enter the main building, turn left, and access the storeroom. Use your lockpicking skills to open chests and obtain Sulphur Wicks, essential for Casper. For extra Groschen, collect five seedlings from the garden behind the main building.

Complete "Under the Straw Hat" by performing tasks like clearing plants and moving sacks (optional). Report to Jerome to finish the quest. Return to Casper, delivering the Sulphur Wicks and seedlings (if collected).

This concludes "In Vino Veritas," allowing you to progress to other quests or activities in Kingdom Come: Deliverance 2.
