It's time for Slipknot Red Cask IOWA Whiskey! Red Cask takes the matured bourbon and rye whiskeys from Cedar Ridge and ages them for an additional year in estate-owned, red wine casks before carefully combining them for this most recent release, building on the success of Slipknot's award-winning No. 9 whiskeys. The resulting product gains a new taste, body, and finishing complexity from the red wine finish while still packing the punch fans have come to expect from Slipknot No. 9.
