I have recently noted that there is a black sealing wax applied to my bottle of Knob Creek bourbon. I know that a previous distiller had red carnauba wax on its bottles (very useful for including in bullet lube) until recently changing over to a plastic sealing substance, so I am wondering if the good folks at Knob Creek may still be using Carnauba in this sealing wax. If any one has knowledge of this I would appreciate your input. Thanks GWW
