Beer-cask-aged whiskey is a bit of a separated-at-birth notion. After all, whiskey basically begins as beer. So why not bring it all back home?
“It essentially sanded down the rough edges that can come with bourbon,” says Brad Kamphuis, the director of operations for New Holland Brewing in Holland, Mich. He’s referring to his beer barrel bourbon and beer barrel rye, which are aged in barrels from the brewery’s popular Dragon’s Milk stout to add a roasty finish to both spirits.
Old Potrero Stout Cask Aged Whiskey ($100 / 750mL)
A dozen years in the making, a few bottles of this are left floating around, but if you come across one of these unicorns, grab it. “What surprised us about this, after all this stuff that the barrel went through, was a hint of some apple,” says Joseph. “But we also got what we expected from a stout—that maltiness. That was something we wanted. And we thought we got a hint of the fresh fruit apple character, too.”
Grant’s Ale Cask Aged Blended Scotch ($19 / 750mL)
Master blender Brian Kinsman started tooling around with different cask finishes, looking to add another layer of interest to his blended scotch. Four months in a cask that once held scotch ale afforded the flavor he sought: a bit of lip-smacking maltiness, honey and (perhaps from the hops) a satisfying citrusy ping at the end.
Glenfiddich India Pale Ale Cask Finished Scotch ($70 / 750mL)
Glenfiddich launched its Experimental Series in the fall of 2016, upping the ante by actually having a beer brewed (and aged in American oak casks) for the purpose of circling those casks back for the whisky. Kinsman partnered with Speyside Craft Brewery’s Seb Jones, who brewed several different versions of an IPA for Kinsman to play around with. The result plays up the herbaceous and citrusy notes in the Speyside single malt, rounded out with a little apple and barrel-centric vanilla.
New Holland Beer Barrel Bourbon ($35 / 750mL)
After 21 years in business, New Holland found a ringer with its uber-popular Dragon’s Milk stout, but the residual barrels they used to age it in were crowding the brewery floor. The solution: Use them to finish its bourbon (40 percent ABV) and rye (44 percent ABV). “It was really having a distillery a-ha moment of innovation based on necessity,” says Kamphuis. “It took three months to really take on the character we were looking for.”Continue to 5 of 7 below.
Jameson Caskmates IPA Edition Irish Whiskey ($30 / 750mL)
Trying to capture the wave of American IPA love, Jameson is collaborating with Wicklow Brewery’s Shane Long on this 2017-launched project. The barrels Shane fills with his IPA begin at Midleton (of course) and then wind up back with the distiller, where they’re filled with whiskey again, yielding an interesting, snappy finish to the usual mellow-sweet trademark Jameson dram.
Chattanooga Whiskey Co. Experimental Single Malt Series “Batch 006” Wheated Native Barrel Whiskey ($80 / 750mL)
The mash bill of this 51 percent ABV whiskey employs three wheated malts (dark wheat malt, caramel wheat malt and oak smoked wheat malt) along with Riverview Farms yellow corn. The finished product goes into Hutton & Smith Brewing Co.'s Wee Heavy Metal ale casks for two months, adding a heady influence of black plum and maltiness to the mix.
Pinckney Stout Cask Whiskey ($20 / 200mL)
Master distiller Tom Anderson of Pinckney Bend Distillery in New Haven, Mo., starts the process for his stout cask whiskey by loaning 15-gallon Missouri white oak barrels to 2nd Shift Brewing in St. Louis for its Liquid Spiritual Delight imperial stout. “We then took the barrels back when they were finished and filled them with our Rested American whiskey,” says Meyer. “Since then, it has become one of our most sought after whiskeys, rarely lasting long once we release the next batch.”
