Probably Stolen - Cyberpunk Shopkeeper Sim: General Chemistry Tips *Solved Alcohol Supply Problem* (Workarounds)
Short answer
No confirmed fix yet. Players suggest: The solution post heating is stable at 59 C.
How to fix it
Work with a small batch – Use roughly 20 ml of mushroom material (dreamcap mush) and mix it with about 120 ml of alcohol. This keeps the alcohol requirement low while still giving a usable amount of extract.
Maintain the optimal temperature – Keep the mixture at 45 °C while extracting. At this temperature the dreamcap compounds dissolve efficiently and the alcohol does not evaporate.
Refresh the mush continuously – Once the first batch of mush has finished extracting, add another 20 ml portion of fresh mush to the same alcohol solution. Keep the temperature steady at 45 °C; the solution will stay stable even after heating.
Scale up cautiously – If you need a larger quantity, you can increase the ratio to about 1 part mush to 6 parts alcohol (e.g., 68 ml mush with 435 ml alcohol). Keep the temperature in the 40‑41 °C range for the first pass, then raise it to 45 °C for the final extraction. The extract volume remains roughly the same, so you’re not losing yield.
Avoid overheating – Dreamcap extract begins to degrade above 60 °C. Do not let the mixture exceed this limit; the solution after heating stays stable at 59 °C, so staying just below that is safe.
Experiment with the water purifier – Some players have run reagents such as acids or bases through the water purifier to see if they survive the process. Give it a try if you need a purified version of a reagent; results may vary.
If it still doesn't work
- Check that the temperature never climbs above 60 °C; even a brief spike can ruin the extract.
- Verify you are using the correct alcohol‑to‑mushroom ratio; too much alcohol can dilute the extract, too little can cause premature boiling.
- Make sure the alcohol you use is the standard type accepted by the chemistry system; exotic spirits may behave differently.
- If the water purifier route fails, consider running the reagent through a different purification method or adjusting the concentration before purification.
What players reported
Just wanted to share my findings from playing around with the chemistry system. *UPDATE* You can get away with small quantities of alcohol for large scale extraction, just do it on small scale (~ 20 ml of mush to 120 ml of alcohol) and continuously add the same portion of mush once the previous has extracted, maintaining extraction temp (45 C for dreamcap). This is my setup…
What players suggest
Nothing else will boil off till 80 C, but dreamcap extract degrades above 60 C. The solution post heating is stable at 59 C. This is actually a good point though, I didn't think it would matter but I just checked and it does. 45 C is optimal, I tested the following on bigger scale: 67.93 ml dreamcap mush to 435 ml alcohol (~6x volume) 40-41 C - 33.96 ml dreamcap extract 45 C - 33.96 ml dreamcap…
Great info here. Has anyone tried running reagents (acids, bases, etc.) through the water purifier on the off chance the reagent survives?
That's crazy. I would never have guessed to try that
Did this work for you?
