Work out distillation alcohol yield instantly with clear inputs, formula shown and shareable results.
Pure alcohol in the wash is volume times its ABV; the still recovers a fraction of that, and dividing the recovered alcohol by the bottling strength gives the finished volume. Alcohol is conserved, not created, so recovery efficiency and wash strength set the ceiling on yield no matter how the run is managed.
Recovered alcohol
litres of pure alcohol = wash litres x wash ABV x recovery efficiency
Bottled volume
bottled litres = recovered pure alcohol / bottling ABV
litres of pure alcohol = wash litres x wash ABV x recovery efficiency. Pure alcohol in the wash is volume times its ABV; the still recovers a fraction of that, and dividing the recovered alcohol by the bottling strength gives the finished volume.
Alcohol is conserved, not created, so recovery efficiency and wash strength set the ceiling on yield no matter how the run is managed.
Enter wash volume, wash strength, still recovery efficiency, bottling strength. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
