Tavern Keeper Vera Experiments: Requirements and Solutions

Vera's experiments in Tavern Keeper require you to transform three experimental barrels inside specialized storerooms during the Gugamush campaign scenario. Unlocking these trials requires reaching a 1-star tavern rating, after which the Orc inventor Vera delivers three barrels with cryptic riddles detailing their environmental triggers. Completing all three unlocks the Scientist achievement, awards 200 gold, and kickstarts the scenario's rocket-building storyline.

Quick Reference: Vera's Experiment Requirements and Rewards

Each barrel requires a specific room condition to trigger its transformation progress bar. You can view the hints in-game by inspecting each barrel's item description and clicking the obscured text.

How to Prepare for the Experiments in Gugamush

Before Vera ships the barrels to your tavern, you must establish a functional baseline in the Gugamush desert:

1. Manage Onic's Back Pay: When your default janitor Onic demands 300 gold in back pay at the end of Day 1, choose the dialogue option to pay him in installments of 40 gold per day over 10 days. Paying the lump sum immediately almost always leads to bankruptcy.
2. Reach a 1-Star Rating: Serve your initial stock, provide clean amenities (such as an outhouse or toilet), and fulfill customer orders to hit a 1-star rating. Governorc will send a 200 gold stimulus grant.
3. Receive Vera's Parcel: Once you earn your first star, Vera delivers the three barrels alongside blueprints for an Infestation Attractor and a cooling fan, plus bonus gold.

To handle the experiments efficiently, partition two or three small storage rooms away from your main customer traffic.

Experiment #1 Solution: High Decoration

The description for Experiment #1 ponders what happens if a barrel is exposed to high culture.

• The Requirement: The barrel must be surrounded by decorative appeal.
• How to Solve It: Place a pallet inside a storeroom or larder and reserve it exclusively for Experiment #1. Place decorative items around the barrel until the item inspection card indicates "Requirements Met." Using high-rating wall decor or 4-star and 5-star furnishings easily pushes the appeal over the threshold.
• Outcome: The progress meter fills over time. Once completed, the barrel transforms into Salty Brine. Salty Brine is a liquid that can be drawn like water and used in cooking recipes, such as baking bread in a bread oven when paired with fine flour.

Experiment #2 Solution: Active Infestation Nest

Experiment #2 references bug digestion and maggot cheese, requiring direct exposure to vermin.

• The Requirement: The barrel must reside inside a room that contains an active Infestation Nest.
• How to Solve It: You can complete this naturally or force it:
  • Forced Method: Build the Infestation Attractor (unlocked via Vera's parcel for 75 gold) inside a dedicated storeroom. This rapidly spawns an insect nest.
  • Natural Method: If your tavern already has an infestation nest due to uncleaned dirt or neglected corners, build a temporary storeroom zone around that nest and place a pallet assigned to Experiment #2.
  • Staff Warning: Ensure your janitors are banned from that specific room or uncheck nest removal while the experiment runs. If a worker destroys the nest with a broom or a Nest Killer bomb before the progress bar reaches 100%, the experiment pauses.
• Outcome: It transforms into Vera's Experiment #2 (Transformed), a pungent, highly volatile chemical liquid.

Experiment #3 Solution: Total Darkness and Isolation

Experiment #3 focuses on sensory deprivation and unobserved isolation.

• The Requirement: Store the barrel in a room with no light and no other items.
• How to Solve It:
  1. Build a small, enclosed room (such as a 3x3 or 4x4 space) zoned as a storeroom.
  2. Ensure there are no windows, lamps, lanterns, candles, or braziers providing illumination inside the room.
  3. Remove all other furniture, shelves, storage racks, and clutter. Place only a single floor pallet set to reserve Experiment #3.
• Outcome: Once the progress bar finishes, the barrel transforms into an Extinguisher Barrel, a handy fire-retardant resource that can be kept in your storeroom to suppress fires.

Critical Storage Bug Warning: Avoid Small Barrel Racks

Players on the Steam community forums noted a bug regarding the storage of experimental barrels. If you assign or place Vera's barrels onto a Small Barrel Rack, staff members can become trapped in an infinite pickup animation loop where the character continually bends down to grab the barrel without moving it.

To avoid this glitch:

• Do not store experimental barrels on Small Barrel Racks or wall shelves.
• Always place them onto standard floor pallets in designated storerooms.

The "You-Reek-A" Story Book: Brazier Choices and Fire Hazards

Once all three barrels finish transforming, Vera returns wearing oiled leather gloves to inspect the results. She dismisses the Salty Brine and the Extinguisher Barrel, becoming fascinated exclusively by the dangerous Experiment #2.

Vera pours the liquid over an unsuspecting customer's head, tastes it herself, and then demands a fire test by throwing the barrel into an open coal brazier.

You face a branching dialogue sequence with distinct outcomes:

1. Agree to the Brazier ("To the brazier!"): Vera hefts the burning brazier over her head, yells "Run!", and throws it at the barrel. The barrel detonates, rocking the tavern. Flaming debris scatters across the room, setting nearby walls, furniture, and stock on fire. Patrons flee in panic while Vera laughs hysterically.
2. Attempt the Smarts Skill Check ("I have some experience with fire..."): You attempt to build a controlled wick using lantern oil techniques. If the skill check succeeds, you avoid incinerating your tavern. If the check fails, the wick sparks an identical explosion and fire hazard.

Regardless of whether the tavern catches fire, Vera pays you 200 gold for your assistance. She announces her next grand ambition: strapping multiple barrels beneath a structure to shoot Orcs into space, setting up the "Rock-It" construction phase of the Gugamush scenario.

Next Steps: Rock-It Fuel and the Gugamush Campaign

Finishing Vera's experiments transitions your tavern into the mid-game phase of Gugamush:

• Guild PR Requirement: Lionel Clipstop from the Tavern Keeper Guild informs you that wealthy patrons will arrive to witness Vera's experiments. You must raise your tavern to a 2-star rating.
• Staffing and Dirt: Sandstorms and furnace heat in Gugamush rapidly raise dirt levels and fire chances. Keep dedicated janitors on floor-polishing duties and place entry mats at every doorway.
• Producing Rock-It Fuel: Vera will soon task you with brewing a 10-barrel batch of Rock-It Fuel. This requires purchasing Rock-It Fuel Base from world-map traders, placing the barrels in an infested room (repeating the mechanic from Experiment #2), and placing cooling devices nearby to prevent high ambient temperatures from causing catastrophic premature detonations.

Frequently Asked Questions (FAQ)

Can I sell Salty Brine to tavern patrons?

No, Salty Brine cannot be served as a standard beverage tap drink to patrons. However, it functions as a water source for kitchen production, allowing you to bake bread recipes at a bread oven when combined with fine flour.

Why is Experiment #2 not progressing?

Experiment #2 requires an active infestation nest in the exact same room. If your janitors destroyed the nest, the progress bar will freeze. Reintroduce a nest by placing an Infestation Attractor (purchasable for 75 gold from your build menu under Storeroom) or allow natural filth to spawn a new nest.

What should I do if an experiment barrel gets stuck?

If a worker gets stuck in an animation loop attempting to move a barrel, check whether the barrel was placed in a Small Barrel Rack, and ensure you reserve a spot on regular pallets instead.
