Bulleit Frontier Whiskey has announced a notable shift from its traditional high-rye recipes with the launch of Bulleit Bourbon Mesquite Smoked Malt Kentucky Straight Bourbon Whiskey. The limited-time release marks the brand's first bourbon to completely omit rye from its mashbill, utilising instead a heavily specialised malting process to achieve its flavour profile.
The new expression aims to capture the growing consumer interest in smoky flavour profiles and specific pairing occasions, particularly barbecue, without relying on artificial additives.

Process and Mashbill Innovation
Rather than adding flavour post-distillation, Bulleit’s R&D team integrated the smoke during the malting phase. A portion of the malted barley is smoked over mesquite wood to impart a signature aroma before fermentation and distillation begin.
The resulting experimental mashbill consists of:
65% Corn
30% Mesquite Smoked Malt
5% Malted Barley
The spirit was distilled at the Bulleit Distilling Co. in November 2018. After ageing for a minimum of six years, it was bottled in the fall of 2025 at 93 proof (46.5% ABV). The higher proof was specifically selected to allow the malty and smoky notes to maintain their intensity when mixed or served over ice.
A Focus on Natural Complexity
Phil Gelineau, Whiskey R&D Manager at Bulleit, emphasised the distinction between this production method and the broader flavoured whiskey category.
"It's important to note that while this release is a first-of-its-kind spirit for the brand, it is not a flavoured whiskey," Gelineau stated. "The subtle smokiness comes from the mesquite wood-smoked malt used in the mashbill. As it has aged, those notes have rounded into something richer and more complex, with layers of brown sugar, caramel, and real depth of body."
Strategic Market Positioning
The release represents Bulleit's first finalised experimental new-make project, signalling a broader strategic focus for the Diageo-owned brand on exploring unique grains and ageing techniques.
By targeting the barbecue pairing occasion, Bulleit is positioning the liquid for casual, food-adjacent environments. "We set out to make a high-quality whiskey that can be enjoyed in casual environments, especially alongside well-prepared BBQ," noted Brian Blackiston, Brand Manager at Diageo for Bulleit Frontier Whiskey.
The Mesquite Smoked Malt release indicates that while Bulleit continues to lean on its Kentucky Straight Bourbon distillation consistency, the brand is actively building a pipeline of experimental variations to engage modern spirits consumers.
