The warehouse in Versailles, Kentucky, caught fire around 11:30 pm. Police Lieutenant Michael Fortney said a security guard called to report the fire.
Forty firemen from five counties helped fight the fire. A second warehouse also caught fire, but this fire was kept under control.
The warehouse where the fire started has collapsed. It contained about 40,000 barrels of alcohol. CNN asked Beam Suntory, Jim Beam's parent company, for an opinion, but received no response.
Drew Chandler, chief of Woodford County Emergency Management, said the camps are huge – about the size of a football field and six or seven stories tall could have ignited the flames. Chandler said the fire was far too big and too hot to bring an investigator near. Even as the sun rose on Wednesday, the fire was still roaring.
"It's deliberately allowed to burn for a few hours," Chandler said. "The more it burns, the less distilled spirits are in the rubble."
This also helps prevent the runoff of fire-fighting efforts from polluting nearby drinking water sources.
