LOUISVILLE, Ky. (Nov. 4, 2025) - - - Bluegrass Bitters ™ has announced the release of its Black Walnut Bitters, the third product added to the brand’s lineup of uniquely curated cocktail bitters and syrups. The Black Walnut Bitters joins the 5-Spice Orange Bitters and Smoky Simple Syrup that launched this summer. Born from founder Shawn Herbig’s scientifically informed craftmanship and deeply rooted passion for authentic libations, the Louisville-based Kentucky Proud certified brand brings this newest cocktail enhancement to customers just in time for the holiday season.

After a successful official brand launch this summer, Shawn’s commitment to providing approachable yet intricate products comprised of only the highest quality, locally sourced ingredients for at-home mixologists, bourbon connoisseurs and the everyday consumer alike, remains the cornerstone of his business model. His pursuit of perfecting each recipe is a testament to the underlying dedication he puts forth with each handcrafted product.

“The Black Walnut was the toughest recipe to crack, with over two dozen different recipes being tested before deciding on this version,” said Herbig.

Customers can expect deep, rich earthy notes when adding these bitters to cocktails. The Black Walnut Bitters incorporate real black walnut and a complement of baking spices to create a complex and aromatic flavor, Herbig notes.

“These bitters are best suited for old fashioneds, Manhattans or holiday ciders, but also work well with other dark spirits and make an outstanding bitters and soda when added to ginger ale,” said Herbig.

The Black Walnut Bitters are available now for purchase online and at select retailers in the coming weeks with a suggested retail price of $13.50. Gift boxes and additional product accessories will be sold and priced separately.
