The 1.75-liter of Buffalo Trace Kentucky Straight Bourbon is the host’s format of Frankfort’s flagship the same low-rye mash bill and new-oak aging, sized for a full bar cart instead of a single shelf slot. Everything that made this the modern benchmark for daily bourbon survives the upsize: vanilla and molasses on the nose, brown sugar and gentle spice through the middle, a long, easy finish at 90 proof. It batches an Old Fashioned for a crowd without flinching and keeps the decanter honest between gatherings. When one bottle of the house pour was never going to last the month, this is the sensible answer.
