Metallica’s collaboration with Blackened Whiskey is growing. The company is sharing the latest release in its “Masters of Whiskey” series.
The blended bourbon is crafted with Rabbit Hole Distillery and is finished in Calvados casks and bottled at a cask-strength proof of 106.59. Calvados is a French apple brandy.
During the finishing period, the whiskey is also “sonically enhanced” with Blackened’s signature technique, which it claims extracts additional flavor from the casks.
The process produces low-hertz sound waves, which causes the whiskey to reverberate at a fast rate in its barrel and interact with the oak staves of the finishing barrel.
The website explains, “Rabbit Hole’s unique mash bills and sourcing malt from Europe, coupled with Blackened Whiskey’s sonic-enhancement process are proof that innovation can come in unexpected ways in whiskey making.”
“We were really looking for something that balanced and layered the flavor profiles together, then added a dash of flavor through the Calvados cask finishing. I’m ecstatic at what we came up with!” -Rob Dietrich, Master Distiller and Blender for BLACKENED Whiskey.
“It seems like it was…more art than science when we came together. It’s always great to be able to work with whiskey makers who are doing new things, such as BLACKENED, as it helps us learn more and improve our game.”- Kaveh Zamanian, Rabbit Hole Distillery’s Founder & Hall of Fame Whiskey Maker.
