Koopers Whiskey has announced the release of Father’s Office Cigar Blend Straight Bourbon Whiskey, a limited-edition expression combining Brazilian Amburana and Japanese Mizunara oak finishes. The two-barrel release, yielding just 378 bottles, will be available beginning June 13, 2026, at the brand’s tasting room in Ledbetter, Texas, and online with presale orders starting June 2.

The eight-year-old bourbon was distilled in Indiana, further aged and blended in Texas, and bottled at 114 proof (57% ABV). Its mash bill consists of 75% corn, 21% rye, and 4% barley.

The finishing process involved Brazilian Amburana oak staves for seven weeks and Japanese Mizunara oak staves for twelve weeks. Amburana oak imparts cinnamon, baking spice, and dessert notes, while Mizunara oak contributes delicate spice, sandalwood, and exotic oak character.

Official tasting notes from the brand describe the nose as opening with "cinnamon sugar, vanilla custard, sandalwood, orange peel, and cigar-box oak." The palate delivers "caramel, toffee, cinnamon toast, peppery rye spice, incense, and oak," while the finish is "long and warming with lingering notes of toasted coconut, dark chocolate, and pipe tobacco."

"Father’s Office, like a cigar, is made for sharing," said Troy Kooper, master blender at Koopers Whiskey. "It’s about slowing down, spending meaningful time with someone who matters to you, and appreciating the evolving layers of flavor through deep conversation."

Kooper added: "Amburana and Mizunara gave us tools to add spice, warmth, and complexity without overpowering the bourbon itself."

Koopers Whiskey is a family-owned Texas whiskey brand founded by Troy Kooper and Michelle Kooper. The company specializes in boutique bourbons and ryes, focusing on maturation, blending, and finishing techniques. The use of Mizunara and Amburana wood finishes reflects a broader trend among American whiskey producers experimenting with non-traditional oak species to create distinctive flavor profiles. Mizunara oak, native to Japan, has gained significant attention across the global spirits industry for its rarity and the complex, incense-like character it imparts, while Brazilian Amburana has emerged as a favored finishing wood for its warm, spice-forward influence.
