Almost 200 bottles of a rare, 20-year-old Kentucky bourbon, Pappy Van Winkle, have gone missing from the Buffalo Trace Distillery in Frankfort, Kentucky. Authorities think that it may have been an inside job.

The spirits are highly coveted. Because the bourbon was held in a secured area, with the distillery located on about 130 acres of land, authorities believe that an employee may have been involved. They are careful to say, however, that the investigation is in its initial stages and will leave "no stone unturned."

The distillery noticed that the bottles were missing on Tuesday. Cases of rye were reported stolen as well.

The bourbon retails for between $100 and $1,000 a bottle online.

On the company's website, Buffalo Trace prides itself on being "the oldest continually operating distillery in America."  Officials say they will monitor the black market and may question sellers of bottles listed for sale.
