The warehouse, in Versailles, Kentucky, became fire around 11:30 pm Police Lt. Michael Fortney said a security guard called for reporting the fire.
Forty firefighters from five counties helped beat the fire. Another warehouse was also fired, but it was controlled.
The warehouse where the fire started has collapsed. It had approx. 40,000 barrels of spirits. CNN reached out to Beam Suntory, Jim Beam's parent company, for comment, but did not receive a reply.
Woodford County Emergency Management Chief Drew Chandler said the warehouse is massive – around the same area as a football pitch and six or seven stories high.
Fortney said there was lightning in the area on Tuesday night and it may have triggered the flames. Chandler said the fire was too big and hot to get a fire researcher near it. Even when the sun rose on Wednesday, the fire still roared.
"It must intentionally be allowed to burn for several hours," Chandler said. "The more it burns, the less distilled spirits are in the waste."
It will also help to ensure that any runoff from fire fighting does not contaminate nearby drinking water sources.
