Old Watermill Rye is the brand name. It was an Old Kentucky Distillery Co. (OKD) label that came with BF's acquistion of that distillery in 1940. OKD was a Louisville distillery, the last vestiges of which were demolished in 1960.
To give all credit where credit is due, although BF distills Rittenhouse, Heaven Hill barrels the new make and ages it.



IMO there's no way they would do all that and not produce our only straight rye...
