Two Jim Beam warehouses in Kentucky caught fire late Tuesday evening, burning approximately 45,000 barrels of bourbon.

One warehouse initially caught fire and spread to a second structure, Woodford County Emergency Management Director Drew Chandler told WKYT.

It is unknown how the fire started but Chandler suggested it may have been a lightning strike.

The fire in the second warehouse has been put out, but five hours after the first fire started, flames were still visible in the initial warehouse.

The blaze and lost barrels are not expected to affect the spirit’s availability to customers, according to Beam Suntory, which owns Jim Beam.
