Method for rapid maturation of distilled spirits using light and heat processes
View Patent ↗An improved system and process for rapidly producing distilled spirits having characteristics associated with a much longer maturation process is provided. The method involves contacting wood with an unmatured distilled spirit under heated conditions and contacting the resulting heat-treated spirit with actinic light. The disclosure provides embodiments where a spirit is sequentially processed through heat and actinic light treatment. The disclosure also provides embodiments where a heat-treated spirit is mixed with a spirit that has been separately treated with light to give characteristics of a mature spirit.

(b) contacting the distilled spirit mixture with wood and actinic light at a wavelength spectrum ranging from 400 nm to 1000 nm from about 12 hours to about 96 hours to give an actinic light-treated distilled spirit mixture; and

(d) contacting the mature spirit of step (c) with wood and actinic light at a wavelength spectrum ranging from 400 nm to 1000 nm for at least two hours from about 12 hours to about 96 hours.
13. The process of claim 12 , wherein the process further comprises:
heating with wood at a temperature between about 140° F. and about 170° F. for a period of time ranging from about 24 hours to about 336 hours after step (d).
14. A process comprising:
(a) contacting an unmature distilled spirit with wood and actinic light at a wavelength spectrum ranging from 400 nm to 1000 nm from about 12 hours to about 96 hours to give an actinic light-treated distilled spirit mixture; and then
(b) providing heat to a mixture consisting essentially of the actinic light treated spirit mixture and wood to maintain a temperature between about 140° F. and about 170° F. for a period of time ranging from about 24 hours to about 336 hours,
wherein the wood has been washed with a solution of carboxylic acid in water prior to step (a), and
wherein steps (a) and (b) are separate and sequential.
15. The process of claim 14 , wherein the unmature distilled spirit is selected from the group consisting of sugar cane spirits, grain spirits, fruit spirits, and agave spirits.
