Probably Stolen wine guide: BloomBerries, water and yeast

How do you start your first bottle?

In-game winemaking diagram showing water, BloomBerries and yeast going into a bottle, then fermenting into wine — Original illustration from the game's BloomBerry Wine Fermenting Guide.

Prepare a Wine Bottle and BloomBerries. One handful makes lower-grade wine; aim for two good handfuls for high-grade wine.
Add High-Quality water or Basewater. Standard yeast is recommended.
Choose “Start Fermenting” in the bottle interface. Top up water or ingredients if the interface says there isn’t enough.
Check the displayed days remaining and wait for the batch to finish.

Berry quality matters most. Pick good fruit first, then check your water and yeast. High-grade wine needs two handfuls, and the fruit’s condition still matters.

Which BloomBerries should you use?

The manual says the best winemaking berries are usually smaller than normal. Set aside overripe, underripe and moldy fruit, then compare the normal and small examples below.

Small BloomBerries from the game manual — **Small**
Prioritize these. The best winemaking berries are usually small.

Normal BloomBerries from the game manual — **Normal**
Use this example to compare berry size and condition.

Overripe BloomBerry illustration from the game — **Overripe**
The manual recommends avoiding overripe berries.

First underripe BloomBerry example from the game — **Underripe, example 1**
Not ripe yet. Leave these out of your wine.

Second underripe BloomBerry example from the game — **Underripe, example 2**
Another underripe appearance to watch for when choosing fruit.

Moldy BloomBerries from the game manual — **Moldy**
Keep moldy fruit out of the batch.

Which water makes good wine?

Use High-Quality water or Basewater. Pure Water lacks the minerals needed for fermentation. Anything below Basewater greatly reduces wine quality.

Test the water you already have before treating it. The water-quality guide explains the six grades and testing tools. For winemaking, aim for the right grade for fermentation.

Which bottle and yeast should you prepare?

Wine Bottle: a fermenting container with an airlock

This bottle has an integrated airlock and is made for fermentation. Once the ingredients are ready, start fermentation in its interface and check the remaining time there.

Standard yeast: recommended for your first batch

Speeds up fermentation and improves wine quality. Without it, wild yeast from the air will ferment the wine, but the results are inconsistent. Standard yeast makes a better starting choice.

Super Yeast: much faster fermentation

Dramatically speeds up fermentation. Check the batch’s remaining days after starting it, then plan your shop work around that.

Yeast Bioreactor: use it again for the next bottle

Provides a renewable supply of yeast. When fermentation starts, it returns to your inventory instead of being consumed, ready for another batch.

Compare bottle and yeast values in the item and base-price reference before buying supplies.

What should you check when a batch goes wrong?

Fermentation won’t start: read the bottle’s message. Add water if it reports a shortage, or check your ingredients if those are insufficient.
Quality varies between batches: check whether you used standard yeast and compare the fruit’s condition. Wild yeast produces inconsistent results.
Wine made with Pure Water turns out poorly: switch to High-Quality water or Basewater to retain the minerals fermentation needs.
You want high-grade wine: prepare two handfuls of good berries and choose suitable water and yeast.

Where do winemaking supplies come from?

Unlocking the Retired Winemaker network upgrade immediately gives you a Winemaking Starter Kit. He first visits the following day, then once a week, selling supplies and equipment.

You can keep sorting stock and running the shop while the batch ferments. The beginner guide covers that routine.
