Process for improving the efficiency of a spirits distillate ageing

The present invention relates to a process for improving the efficiency of a spirits distillate ageing comprising the following steps: a) preparing: at least one reactor, wood chips or cubes, at least one ultrasound source, a distillate to be submitted to 5 ageing; b) introducing the wood chips or cubes and the distillate into the at least one reactor; c) inserting the at least one reactor prepared in the previous step into the at least one ultrasound source; d) operating the ultrasound source and allowing the distillate to age, wherein: in step a) of preparing the at least one reactor, wood chips or cubes, at least one ultrasound source, a distillate to be submitted to ageing, wood chips or cubes whose surface area is between 70 and 500 cm2 10 per litre of distillate are used; step d) of operating the at least one ultrasound source and allowing the distillate to age is carried out in the absence of light, at a temperature between 0 °C and 40 °C, with a number of operating-rest cycles of the at least one ultrasound source between 200 and 4500.
