Abstract
Alcoholic spirits may be artificially aged under highly pressurized carbon dioxide. The carbon dioxide may form carbonic acid, which may cause various esters to form in the presence of wood as well as to mellow the flavor when no wood is present. Wood may be pretreated with ozone, which may extract lignin which may further convert to vanillin during pressurized CO2 treatment, giving a vanilla note. After processing with pressurized CO2, a post-treatment of ozone may be given to the spirit, which may cause a mild oxidation and further mellowing of the spirit.
