1. Blackened: Metallica's Rye the Lightning 

Rock legends Metallica made waves in the whiskey world with their limited-edition Blackened: Rye the Lightning. This unique rye whiskey is aged while blasting the band's iconic album "Ride the Lightning," a technique known as “Black Noise sonic enhancement.” This innovative process, developed in collaboration with sound engineers at Meyer Sound, utilizes low-hertz sound waves to create vibrations that cause the whiskey to reverberate rapidly. This interaction with the oak staves of the barrel reportedly enhances the extraction of wood compounds and flavors. After the sonic aging, the whiskey undergoes a double finishing in Madeira wine and Caribbean rum casks. According to Metallica, the result is a complex spirit filled with notes of dried fig, pinewood, and clover honey.

 2. Belgrove Distillery Wholly Sh*t Rye Whiskey 

On the other side of the world, Belgrove Distillery in Tasmania is committed to sustainability and innovation, exemplified by their Wholly Sh*t Rye Whiskey. This unique spirit is crafted using a distinctive method: the sheep’s manure from Belgrove’s own flock is burned to produce smoke, which is then injected into a wet barrel. This innovative technique captures unique smoke compounds, resulting in a rich and complex flavor profile that sets this whiskey apart from traditional peated varieties. With only a limited number of bottles available, this abstract release is destined to be highly collectible. Its distinctiveness even caught the attention of Gordon Ramsay, who featured it in his docuseries UNCHARTED, further solidifying its unique place in the world of whisky. If you whiskey fan who loves stepping into the obscure, “Wholly Sh*t Rye Whiskey” is definitely worth a try.

3. WhistlePig Legends Series: Alfa Romeo F1 Team Stake Barrel 

Always at the forefront of innovation, WhistlePig  are certainly not afraid to experiment. This time around, WhistlePig has taken rye whiskey to the racetrack with their limited-edition Piggyback Legends Series, created in collaboration with the Alfa Romeo F1® Team. This high-rye whiskey is not only selected by race car drivers but also undergoes a crazy aging process. In their own words, Whistlepig tests these barrels in a wind tunnel, “to ensure a thrilling taste in every sip”. If that wasn't enough, these barrels were subjected to varying levels of G-Forces at the Whistle Pig farm and distillery; according to WhisltePig this process enhances the interaction between the whiskey and the wood while staying true to the dynamic spirit of Formula 1. At this point we aren't even surprised by Whistle pigs seemingly limitless creativity; we’re curious to see what they have in store for future releases.

4. Jefferson's Ocean Aged at Sea Bourbon 

Hailing from Louisville, Kentucky, Jefferson's has taken aging to new depths—literally. Jefferson's Ocean Aged at Sea Bourbon is matured on a ship that sails the world’s oceans, allowing the bourbon to interact with the wood of the barrels in a dynamic way. According to Jeffersons, the constant motion of the waves, coupled with exposure to salty sea air and fluctuating temperatures, creates a unique profile in each release. With 25 different voyages completed so far, each addition to this collection tells its own story, making every bottle a singular experience.

5. Cleveland Whiskey  

Cleveland Whiskey takes an innovative approach to aging with their patented Pressure Aging™ process. Cleveland Whiskey’s Founder Tom Lix believes in challenging traditional bourbon norms, creating spirits that can be ready to drink in less than a week, rather than the typical eight to twelve years.  Their unique method involves filling a stainless-steel vat with freshly distilled liquor and adding cut-up pieces of oak, which are agitated under pressure to mimic years of aging in just a few days. This process was applied to their Black Cherry Wood Bourbon, that resulted in a spirit that is “unquestionably and deliciously different”.

6. Abasolo Whisky 

From Mexico comes Abasolo, a whiskey crafted from 100% Mexican Cacahuazintle corn. This spirit stands out for its unique production method that includes nixtamalization, an ancient 4000-year-old technique where the corn is soaked and cooked in an alkaline lime bath before being hulled; Interestingly this technique is typically used in making tortillas. The combination of nixtamalized and malted corn undergoes an extensive fermentation process before aging in both new and old casks, resulting in a rich and flavorful whiskey that highlights the terroir of Mexico. Located at one of the highest altitudes among whiskey distilleries, Abasolo benefits from cool temperatures that promote a distinctive aging process. The distillery has repurposed horse stables into open-air warehouses, allowing the whiskey to expand and contract rapidly in the barrels due to temperature fluctuations.

7. Mystic Galactic Whiskey 

Not released yet, Mystic Distillery plans to send barrels of bourbon to Low Earth Orbit for one year of aging! The first whiskey to be aged in space! Currently aging in new charred oak barrels, these will be reinforced with titanium hoops before being launched into space aboard the Nyx, a rocket from Berlin-based The Exploration Company. Founder Jonathan Blitz explained that the barrels will need to be dumped and re-barreled for the journey, with baffles added for stability to prevent the spacecraft from flipping during reentry. After a year in orbit, the orbiter will splash down in the ocean—hopefully with some stellar whiskey on board. 

As for whether bourbon can be aged in space, Mystic Distillery is sure that once it’s in a new charred oak container, it qualifies as bourbon. Though they initially faced regulatory hurdles, the distillery ensures the label will proudly read “bourbon whiskey,” perhaps with a note about its orbital adventure! This Bourbons price tag is quite literally out of this world, set at $75,000 and limited to around 1200 bottles! 

8. Glenmorangie A Tale of the Forest 

Glenmorangie’s A Tale of the Forest is a tribute to nature, using a traditional technique of kilning barley with woodland botanicals like juniper, birch bark, heather and rowan. This unique approach imbues the whiskey with aromas reminiscent of a forest and is meant to result in aromas of sweet campfire smoke and notes of notes of fresh mint, sweet pine sap, and dried berries. The creation of A Tale of the Forest stirred some controversy with the Scotch Whisky Association, which raised concerns about the inclusion of botanicals—a practice historically used in Scotch production, though Glenmorangie was able to overcome this obstacle releasing “A Tale of Forrest” in midway through 2022.
