This limited-release Straight Bourbon Whiskey builds on the success of Filibuster’s Dual Cask straight bourbon and Straight Rye Whiskey. Blending 6- year-old high Rye bourbon From MGPI & 5-year-old Sweet Mash Filibuster Straight Bourbon, we complete the aging with a long finish in Madeira Casks for 11 months. The result is a uniquely balanced, handcrafted, high proof whiskey offering a complex and distinctive expression of Straight Bourbon with an incredibly smooth finish.
