Gray provided full civil, structural, architectural, and mechanical/electrical design and construction for the distillery and barrel-aging warehouse. Gray’s onsite technical team handled coordination of all building trades with mechanical, electrical, and equipment installation subcontractors.


Gray Solutions, a Gray company provided automation & controls for the project, including I/O panels and PLC coding for the distillery process.
