Abstract: Alcoholic liquids ready for aging and contained in vessels such as bottles, casks and the like are submitted to low-frequency polarized pulsating magnetic fields. Fields are produced by air-core wound solenoids made of an electric conductive wire and disposed close to the vessels. Solenoids are connected individually or by groups to respective generators adapted to supply a low-frequency pulsating current of 50 Hz for example. Solenoids can be incorporated in panel-shaped containers or fastened to support structures to be associated with a plurality of vessels holding the liquids for aging.

Abstract: The apparatus comprises at least one panel container (12) carrying a plurality of air-core solenoids (3) connected individually or by groups to respective generators adapted to supply the solenoids (3) with such pulsating currents that relative magnetic fields are created on the supported products (2) adjacent to the panel containers (12). The panel containers (12) can be movable and the containers themselves can carry the products (2) to be submitted to maturing. The process provides for products (2) to be submitted to the action of low-frequency pulsating polarized magnetic fields during their maturing cycle. The intensity and/or frequency of the fields is adjusted depending on the amount of liquid and/or weight and/or type of product being matured. The action of the pulsating magnetic fields on the products (2) leads to an important reduction in the maturing times and an improved quality of the final products.
