Sunny Brook has been a cat and dog for Beam since the National Distillers buyout in 1987. Prior to that, it had been distilled at probably ND’s Grand Dad or Crow distilleries during the 70s and 80s. It was its own distillery in Louisville at 28th and Broadway 1892 until sometime prior to 1975, when that distillery was razed (it’s fun to pull out Sam Cecil’s book, that’s where all this info came from).
