Evaporation = concentration
As mentioned earlier, a portion of the volume of the eaux-de-vie evaporates during ageing.
Alcohol and water, as the main components of eaux-de-vie, are lost in the highest quantity. Other volatile compounds evaporate in greater or lesser proportion. The least volatile compounds become more concentrated.
