Every family has at least one member they don’t acknowledge publicly. For what’s said to be the mash bill number two bourbons made by Buffalo Trace, that unacknowledged member is Hancock’s President’s Reserve single barrel bourbon. Other brands of the mash bill number two family include Blanton’s, Elmer T. Lee, Rock Hill Farms, and Ancient Age.Buffalo Trace bottles Hancock’s as a single barrel expression at 88.9 proof (the lowest proof among single barrel mash bill number two bourbons), with no age statement. As mentioned in previous reviews, Buffalo Trace’s mash bill number two includes approximately 12-15% rye grain, which is the highest rye content mash bill of their bourbon offerings.
