You can try, but you're better off starting a separate batch because the higher the ethanol fraction of the mixture becomes the less efficient the yeast become. If you want to make sure you get all the potential out of a batch you can distill off the ethanol from the mix and then rerun it.

>>25451963 I see. It would be better to filter out the dead yeast and other stuff before referment it right?

heres a website that shows you how to make a gizmo to distill the ethanol. https://skunkpharmresearch.com/alcohol-reclaim-still/

>>25451974 Alright thanks. There may come up some threda of my science on monday.

>>25451969 non necessarily, the dead yeast contains some nutrition that the live yeast will feed off of, but how you do it depends on how badly you want to get maximum productivity our of your ingredients vs how much you want to get maximum productivity our of your labor. and alcohol is so cheap on the goymoney so why even bother to begin with?
