Carbon Neutral Distillery.

Diageo is among the world’s largest spirits producers, and when the company decided to build a new distillery in Kentucky, it turned to Gray as its design-build partner for the project.

Leveraging its deep industry experience and resources, Gray integrated complete turnkey solutions for the customer’s bourbon distillery, dried grain facility, and barrel-aging warehouses within the state-of-the-art operation. The complex features an automated distillery process—including granary, mash cooking, fermentation distillation, and barrel filling processes—and an annual production capacity of 10 million proof gallons.


Gray scope included full architectural and MEP design as well as construction for the distillery and seven barrel-aging warehouses. Gray’s onsite technical team handled coordination of all building trades with mechanical, electrical, and equipment installation subcontractors.


Gray provided automation & controls for the project, including I/O panels and PLC coding for the distillery process. As the process integrator for the Diageo Lebanon Distillery project, Gray was responsible for the development of the mass and energy balances, PFD and P&ID, equipment general arrangements and stack-ups, process equipment procurement, and vendor management. Rounding out its robust service offering, Gray provided manufacturing network architecture design, installation, and integration with the business LAN.


The new facility will bring more than 30 full-time jobs to the area. Even more impressive, the facility is completely carbon neutral, powered by 100% renewable electricity throughout the cooking, distillation, and dry house processes.


“Gray is proud to play a role in the carbon neutral efforts happening at the Diageo Lebanon facility,” said Stephen Gray, president and CEO of Gray. “Diageo’s commitment to sustainability will no doubt impact and challenge the industry toward advancement.”
