Re: Purity Vs Flavour
- The flavours come out even in high purity reflux still (95-96%). They
are just separated more during the length of the run. If the still
reaches equilibrium and output is slow enough you'll get the stuff
out in order of boiling points with little mixing at transition
points. Makes it easy to cut out unwanted components and have very
pure ethanol during the middle run.
