Describe the chemical mechanisms of 'Angel's Share' during spirit maturation.

The 'Angel's Share' refers to the loss of spirit volume during maturation in wooden barrels. This loss occurs due to evaporation through the porous wood of the barrel. The chemical mechanisms driving this evaporation involve the diffusion of volatile compounds from the spirit into the surrounding environment. Ethanol, being a relatively small and volatile molecule, is a primary component of the Angel's Share. It diffuses through the wood at a rate influenced by temperature, humidity, and the specific characteristics of the barrel. Water also evaporates,....
