The distillation and hydrometry method of determining alcohol concentration in distillate is one of the cheapest and simplest to perform with the least chance of. We distill a wine (12 % alcohol by volume) sample and collect a series of samples, recording boiling points and determining density of our primary fraction in.
Distillation is a method for separating two or more liquid compounds on the basis of boiling-point differences as each component boils at a different temperature.
