If you’ve just purchased raw materials, equipments or any stills for sale, try not to be too excited that you make yourself forget the basics in distilling alcohol. If you’re a novice, the following are common questions you need to ask before embarking on the craft of distilling.
What does distillation mean?
Ethanol distillation involves the boiling as well as re-condensing of ethanol, water and trace liquids such as congeners, higher alcohols, fusel oils. The objective of distillation is to decrease the amount of water while increasing ethanol and removing most, if not all, of the trace liquids. This process is made possible due to ethanol and water’s contrasting boiling points.
Take note that ethanol’s boiling point is lower than that of water. Therefore, the vapor that boils off from a mixture of ethanol and water will carry more concentration of ethanol compared to the liquid where the vapor originated from. Essentially, the distillation process is the science of perfecting and controlling these effects.
