The Copper & Kings Distillery in Louisville, Kentucky have a unique weapon when it comes to making their signature spirits sing with flavor through the use of “sonic aging”, a process that uses sound vibrations to excite the maturing liquid within the barrels. Music blasts at the distillery all day and all night, all different varieties, genres and styles. In an interview with Munchies, founder Joe Heron talks his belief that “happy brandy makes happy drinking”.
Heron …believes that the gentle vibrations of the music assist in the aging process for his craft spirits, absinthe, and brandy. By pushing frequencies inside the barrel, liquid constantly circulates, causing more surface contact with the oak barrels. Unlike bourbon, which moves in and out of the oak due to changes in temperature, his nuanced indie brandy calls for finesse and tender coaxing.
