The April 24 explosion at Marshall County's Silver Trail Distillery left employees Jay and Kyle Rogers with burns over 80 percent of their bodies. Kyle Rogers died from his injuries and Jay Rogers continues to recover.
Rogers and Silver Trail owner Spencer Balentine filed their lawsuit against the Oregon-based Revenoor Company on Monday.
The Kentucky Fire Marshal is still investigating the explosion, which it has said was caused by a "catastrophic equipment failure."
The Silver Trail Distillery produces "LBL Moonshine," named for the nearby Land Between the Lakes National Recreation Area.
