Probably Stolen wine guide
To make wine in Probably Stolen, fill a Wine Bottle with 750 ml of water, put BloomBerries and yeast into its ingredient slots and press Start Fermenting. A hidden wine score, built from berry condition, yeast and water quality, decides the quality tier. Two good berries, any yeast and clean water already reach the top tier, Master Vintage.
How do you unlock wine making?
Buy the Retired Winemaker network upgrade (200 credits). You immediately receive a Winemaking Starter Kit, and a retired winemaker visits the next day and then once a week, selling winemaking supplies and equipment. The upgrade unlocks the winemaking content; the BloomBerry Wine Fermenting Guide document is a 25-credit item.
What do you need for each bottle?
| Item | Role | Base value |
|---|---|---|
| Wine Bottle | Fermentation vessel, 750 ml, built-in airlock | 12 |
| BloomBerry | Main ingredient; each berry has a random condition | 14 |
| Yeast | +1 wine score, fermentation takes 2 nights | 10 |
| Super Yeast | +1 wine score, fermentation takes 1 night | 20 |
| Yeast Bioreactor | Works like Yeast but is returned to you when fermentation starts | 250 |
| Synthetic Yeast | Illegal; makes cheap counterfeit wine and needs no berries | 8 |
| AgeWell | Machine that ages finished wine faster | 350 |
You grow BloomBerries from Bloomberry Seed in a Hydroponic System (see the hydroponics guide). The bush is perennial: it keeps fruiting after harvest.
How is wine quality calculated?
The game adds up a wine score when fermentation starts:
- Each berry: a berry’s condition counts directly if positive (+1 or +2). A negative berry counts one less badly: condition -1 counts as 0 and -2 counts as -1.
- Two or more berries: +1.
- Any yeast: +1.
- Water quality: the water you filled the bottle with adds or subtracts points by purity.
| Water | Purity | Score |
|---|---|---|
| Pure Water | 99.9% and up | +1 |
| High-Quality Water | 99-99.9% | +1 |
| Basewater | 98-99% | 0 |
| Ghostwater | 96-98% | -1 |
| Rustwater | 90-96% | -2 |
| Gutterflow | below 90% | -3 |
| Total score | Tier | Value modifier |
|---|---|---|
| 6 or more | Master Vintage | +75% |
| 5 | Reserve | +50% |
| 3-4 | Production Wine | +25% |
| 2 | Homebrew | 0% |
| 1 | Bucket Brew | -15% |
| 0 or less | Undrinkable | -100% |
Finished wine has a base value of 100 credits before that modifier. Reserve and Master Vintage count as luxury items, and drinkable wine is classed as alcohol.
Example: two berries with condition +2 (4 points), the two-berry bonus (+1), Yeast (+1) and Pure Water (+1) make a score of 7, which is Master Vintage.
How good are the berries you grow?
A harvested BloomBerry’s condition is rolled from the plant’s health at harvest:
| Plant health | Condition outcomes |
|---|---|
| 25% or less | -2 (55%), -1 (45%) |
| 26-55% | -2 (25%), -1 (45%), +1 (30%) |
| 56-85% | -1 (25%), +1 (45%), +2 (30%) |
| above 85% | +1 (40%), +2 (60%) |
Keep the plant’s water clean and its minerals in range to protect its health. The seed’s own description says the same: keep its water clean for better BloomBerries.
How long does fermentation take?
A bottle needs 4 units of fermentation, and each night removes as many units as the yeast’s power. With Yeast (power 2) it takes 2 nights, with Super Yeast (power 4) it takes 1 night, and with no yeast it takes 4 nights. The bottle’s tooltip shows the nights remaining.
What does the Synthetic Yeast do?
It is an illegal substance that replaces yeast and “requires only water”. The result is GloomBerry Wine: a contraband item worth 44 credits, drinkable, fixed score 3 and unable to age. It is cheap and described in-game as mildly carcinogenic. It does not use the BloomBerry route and is not a way to reach higher tiers.
How does the AgeWell work?
Finished wine gains 3 credits of value for each day it ages. The AgeWell works overnight with power and a finished bottle of wine, and ages the bottles inside it by one extra day each cycle. Its Quality stat adds one more day per 125 Quality; Efficiency and Performance only change its power use. Counterfeit wine cannot be aged.
FAQ
How much water does a bottle need? At least 749 ml of the 750 ml capacity, otherwise the game says there is not enough water to start fermentation.
Can I start with no berries? Only with Synthetic Yeast. Otherwise you need at least one ingredient.
Can I empty a bottle? An unstarted bottle can be drained into a drain or another container. A finished wine bottle can be poured into a container and becomes an empty bottle again.
Is the Yeast Bioreactor worth it? It never runs out and gives the same power as plain Yeast (2), so it pays for itself after many batches.
