Nelson Bros Black Brier Straight Bourbon Whiskey is a bold and imaginative expression from the Nelson Brothers Cask Finish Series. In a unique collaboration with Blackstone Brewing Company, this bourbon is finished in barrels that once held rich, malty Imperial Stout ale. The result is a masterfully crafted whiskey that bridges the depth of stout beer with the warm complexity of bourbon, yielding a distinctive, layered drinking experience that honors both tradition and innovation.
