The flavor of Blackened American Whiskey is sonically enhanced through an expert-developed scientific process. Metallica worked with scientists, acoustic and audio engineers, designers and technicians of Meyer Sound to develop the patented BLACK NOISE™ system. This sonic enhancement delivers a precise range of low hertz soundwaves into the oak casks causing the whiskey to interact with the charred oak staves, measurably releasing compounds for flavors like toasted coconut, vanilla, butterscotch, and caramel. The process is BLACK NOISE™. The result is one-of-a-kind Blackened Whiskey flavor.
