Obviously you don't want to drink this alcohol, but alcohol has many uses like fuel and solvents. Yeast like any other creature need complete nutrition and how do you do that when you don't have access to complex ingredients in a societal collapse?
Urine. Thats right. Urine is an excellent source of nitrogen, potassium, and phosphorus and all the trace elements. The only other thing they need are carbohydrates. Sugar works, fruit juice, things like that.
Here is a recipie I designed. It is called SPY broth. Sweet Pee Yeast broth ;).
200 mL Clean sterile urine (about 1 urination)
200g Sugar (1 heaping cup)
1/4 tsp active dry yeast
Fill up to 1 L with pure water
Mix this up and let sit 4-5 days. It should reach roughly 15% ethanol. You should be able to comfortably expect 100mL of pure alcohol from that recipe for literally just a quarter or two.
And thats it! If it is legal you can distill it to roughly 95% ethanol which would be very clean and can be used as a solvent or fuel, cars will run on it even, and you can make alcohol lamps. Scrub it with some activated charcoal powder and you have a product that would rival Grey Goose lol. To scrub it with activated charcoal in 100mL of ethanol mix in 1 tsp of activated charcoal powder, mix well, and filter through a coffee filter. In a situation where you don't have a coffee filter you can add 1 tsp diatomaceous earth or alum and stir in to make it settle out so the ethanol can be poured off clean and clear.
