Master the art of Finnish sugar wine production in My Winter Car. Learn the perfect 6-sugar recipe, 2.5-hour fermentation process, quality control techniques, and how to sell to Jouko for maximum profit (160mk per bottle). This comprehensive guide covers everything from ingredients to economics. Verified for Early Access v.260102-01.
My Winter Car is in Early Access development (launched December 29, 2025). Kilju mechanics, fermentation timing, prices, and Jouko behavior may change with patch updates. This guide is based on v.260102-01 (January 2, 2026) and includes changes from My Summer Car where relevant.
Kilju (pronounced "keel-you") is a Finnish homemade sugar wine created using only three simple ingredients: sugar, yeast, and water. It gained popularity in Finland during the economic recession of the 1990s as an extremely cheap method to produce alcoholic beverages at home.
Kilju serves three critical functions in the game:
The recipe is actually printed in Finnish on the back of sugar bags in-game, reflecting the real-world practice during 1990s Finland. My Winter Car is set in 1999, making kilju a culturally and historically accurate element of the game's survival mechanics.
Result: ~20 bottles at 160-170mk per bottle (highest price from Jouko)
| Recipe | Sugar | Yeast | Value Per Bottle | Notes |
|---|---|---|---|---|
| Perfect Batch | 6 bags | 1 bag | 160-170mk | Highest profit - recommended |
| Weaker Batch | 5 bags | 1 bag | ~130mk | Lower alcohol content |
| Minimum Batch | 4 bags | 1 bag | ~120mk or less | Not recommended |
The 30-liter bucket requires 6 bags of sugar to achieve optimal fermentation. Using fewer bags produces weaker kilju that Jouko will pay significantly less for. The price difference (170mk vs 130mk per bottle) means losing ~800mk per batch by using only 5 sugar bags.
Pro Tip: Buy sugar and juice every time you visit PSK. Stock up so you can brew multiple batches without waiting for restocks.
Go to your apartment bathroom. The 30-liter brewing bucket is sitting on the floor or near the sink. Pick it up.
Take the bucket to the shower or sink. Fill it completely until water reaches the rim. The bucket holds exactly 30 liters when full.
Alternative: Some players submerge bucket in lake, but apartment shower is more convenient.
Drop 6 bags of sugar and 1 bag of yeast into the water-filled bucket. Order doesn't matter - both ingredients can be added at once.
CRITICAL: Close the bucket lid right away. Fermentation begins as soon as the lid is sealed. You should hear bubbling sounds start within moments.
Standard Time: Approximately 2 hours 30 minutes real time
Speed Up Trick: Place bucket next to radiator set to 30°C to reduce fermentation time
How to Tell It's Ready: Listen for bubbling sound. When bubbling completely stops, kilju is finished.
You can carefully open the lid to check progress:
Visual Check Tip: Crouch once (C key), then lean forward (Q key) to see inside bucket more clearly
If you leave the lid open for extended periods during fermentation, vinegar will develop. This ruins the batch and makes it worthless.
Lid closed, bubbling begins immediately. Loud, frequent bubbling sounds.
Bubbling continues at steady pace. Orange layer visible on top if you check.
Bubbling slows down noticeably. Sound becomes less frequent.
Bubbling stops completely. Yeast settled at bottom. Ready to bottle!
Before bottling, you need 20 empty plastic juice bottles:
Once fermentation is complete and bubbling has stopped, carefully remove the lid. Don't spill!
Take an empty juice bottle and dip it into the bucket. You'll hear bubbling sounds as the bottle fills. No need to drop the bottle - just drag it into the kilju.
Make sure each filled bottle is properly capped. Keep all bottles from the same batch together.
Load all 20 bottles into any vehicle with enough cargo space. Sorbett trunk works well, or use van if available.
Jouko "Jokke" Ollevi is your neighbor who lives next door to your apartment (to the right). He's easy to spot: wears turquoise sweatpants, KurPa beanie, and no shirt even in winter.
Night Parties: Jouko occasionally parties at night with loud music and flashing lights. You can visit during parties for free beer and spirits.
Load all 20 kilju bottles into vehicle, drive to townhouse next door. Park outside, bring bottles to his table.
Find Jouko sitting at his table. Place one kilju bottle on the table next to him. Wait for him to pick it up and taste it.
Jouko will drink from the bottle to test quality. Based on your recipe:
Keep placing bottles on table one by one. Money accumulates in Jouko's hand - you don't need to take it after each bottle.
After ~3 bottles, Jouko will demand you drink one with him. You must drink or he won't buy more. He may ask again every 1-5 bottles.
Important: You don't get paid for bottles you drink with him!
After selling all bottles, take the accumulated money from Jouko's hand. Transaction complete!
According to player reports, Jouko pays 20mk less per bottle as you sell more in My Winter Car. This is a new mechanic not present in My Summer Car.
Example: First bottle 170mk → Second bottle 150mk → Third bottle 130mk, etc.
Note: This mechanic is still being verified by community. May vary by patch version.
You can safely drink up to 3 high-quality kilju bottles before passing out. Drinking more causes blackout.
After selling kilju, empty bottles can be found at the landfill site:
| Item | Quantity | Price Per Unit | Total Cost |
|---|---|---|---|
| Sugar | 6 bags | ~13mk | ~78mk |
| Yeast | 1 bag | ~10-15mk | ~15mk |
| Juice (for bottles) | 20 bottles | Free (already paid) | 0mk* |
| Total Investment | ~93mk | ||
*Juice cost not counted as you consume it for survival, bottles are byproduct
| Scenario | Price Per Bottle | Bottles Sold | Total Revenue |
|---|---|---|---|
| Best Case (No Decrease) | 170mk | 20 | 3,400mk |
| With Drinking Tax | 170mk | 17 (3 drunk with Jouko) | 2,890mk |
| Weak Batch (5 Sugar) | 130mk | 17 | 2,210mk |
Perfect recipe (6 sugar), accounting for 3 bottles drunk with Jouko
Investment: 93mk | Revenue: 2,890mk | Profit: 2,797mk
Total Active Time: ~22 minutes per batch
Hourly Rate: ~7,600mk per hour of active work (extremely profitable!)
| Method | Time Required | Income | Notes |
|---|---|---|---|
| Kilju Brewing | 22 min active | ~2,800mk | Best early-game method |
| Taxi Job | ~1 hour | ~500-800mk | See Jobs Guide |
| Septic Pumping | ~1 hour | ~400-600mk | Requires Gifu truck |
| Futufon Factory | 8 hours/day | ~200-300mk/day | Steady but time-consuming |
Kilju has dual purpose - income AND survival:

Goal: 10,000mk for Rivett Parts
Strategy: Brew 1 batch per day while working factory job or building Rivett. Kilju provides the capital needed for car parts while you earn from other sources simultaneously.
A: Approximately 2.5 hours of real time. You'll know it's done when the bubbling sound stops completely. Placing bucket next to a radiator set to 30°C speeds up the process.
A: Three possible reasons: (1) You used less than 6 sugar bags (weak brew), (2) New MWC mechanic reduces price by 20mk per bottle sold, (3) You opened lid too long during fermentation causing quality degradation.
A: Jouko lives in the townhouse immediately next door to your apartment (to the right). Visit in the evening (5:30-7:00 PM window). He wears turquoise sweatpants and a KurPa beanie.
A: Yes! Drinking kilju lowers the Problem Bar just like beer. It's much cheaper than buying beer from PSK (kilju costs ~5mk per bottle to make vs 20-30mk for store beer).
A: Up to 3 high-quality kilju bottles are safe. Drinking a 4th bottle will likely cause blackout. Jouko will force you to drink ~3 bottles when selling a full batch.
A: Empty bottles spawn at the landfill site. Check near the lamp post, outhouse area, and hills surrounding the landfill to recover them for reuse.
A: Quick checks are fine, but leaving the lid open for extended periods causes vinegar to develop, ruining the batch. Jouko will pay very little or refuse vinegar kilju.
A: 6 bags is optimal for the 30L bucket. Using more doesn't increase value and wastes sugar. Stick to the 6:1 ratio (6 sugar, 1 yeast).
A: Absolutely! Kilju brewing takes only ~22 minutes of active work for ~2,800mk profit. That's ~7,600mk per hour, far exceeding any job in the game. The fermentation time is passive - you can do other tasks while waiting.
A: Aging doesn't increase sale price to Jouko, but it does make the drunk effect stronger when you consume it. This only matters if you're drinking kilju for the Problem Bar.
