Abstract: The method for accelerated ripening and aging of alcoholic beverages such as distillates and red wines, comprises supplying a short-wave radiation (15) in a shorter wavelength region below 340 nm for a certain radiation time to the alcoholic beverage to be treated, and supplying the alcoholic beverage to be treated to a UV-permeable tube (13) such as a quartz tube. A radiation (14) emits in a shorter wavelength region, which partially comprises ultraviolet spectrum and a radiation source (11) that is laterally arranged next to the UV-permeable tube. The method for accelerated ripening and aging of alcoholic beverages such as distillates and red wines, comprises supplying a short-wave radiation (15) in a shorter wavelength region below 340 nm for a certain radiation time to the alcoholic beverage to be treated, and supplying the alcoholic beverage to be treated to a UV-permeable tube (13) such as a quartz tube. A radiation (14) emits in a shorter wavelength region, which partially comprises UV spectrum and a radiation source (11) that is laterally arranged next to the UV-permeable tube in a longer wavelength region above the shorter wavelength region, where the radiation is prevented by a shield (12) arranged between the radiation source and the UV-permeable tube in the longer wavelength region at a direct strike on the UV-permeable tube and splits by a dichroic filter such as a dichroic mirror in the short-wave radiation into the shorter wavelength region and a long-wave radiation into the longer wavelength region. The dichroic filter is arranged/formed in such a way that the short-wave radiation hits on the UV-permeable tube and the long-wave radiation is lead away from the UV-permeable tube. The radiation source is formed as a mercury-medium pressure discharge lamp. The shield and the dichroic filter are formed as a unit, where the dichroic filter is formed as the dichroic mirror. The short-wave radiation is reflected by the dichroic mirror in such a way that the short-wave radiation hits directly and/or indirectly at the UV-permeable tube and the long-wave radiation is passed through adjacent direction by the dichroic mirror at the UV-permeable tube in such a way that the UV-permeable tube is free form the long-wave radiation. An emitted radiation is reflected from the radiation source by a first concave mirror such as a first mirror channel or a first parabolic mirror such as a first parabolic trough, on the dichroic mirror, where the dichroic mirror of the short-wave radiation is reflected in the direction of UV-permeable tube so that a first part of the short-wave radiation directly hits on a side facing towards the dichroic mirror of the UV-permeable tube and a second mirror such as a second mirror channel or a second parabolic mirror such as a second parabolic trough that surrounds the UV-permeable tube on the side facing away from the dichroic mirror and a second part of the short-wave radiation is reflected in the direction of the UV-permeable tube so that the second part of the short-wave radiation hits on the side facing away from the dichroic mirror. The alcoholic beverage to be treated is continuously passed through the UV-permeable tube with a constant flow rate, where the radiation time of the alcoholic beverage is controlled over the flow through of a pump. A turbulent flow is produced into the UV-permeable tube so that the alcoholic beverage is applied uniformly with the short-wave radiation. The alcoholic beverage remains into the UV-permeable tube for the certain radiation time to an impact with the short-wave radiation, and is guided after course of the radiation time from the UV-permeable tube. An independent claim is included for a device for accelerated ripening and aging of alcoholic beverages such as distillates and red wines.
