Chicago Tribune: "While Knob Creek has sold single-barrel releases in the past, the 12- to 13-year-old bourbon featured in the 25th Anniversary Bourbon is the distillery's first-ever unfiltered, cask-strength, single-barrel bourbon... Given that the release stems from roughly 300 barrels, that means there are 300 different versions of the 25th Anniversary Bourbon... Some are woodier, while others have more pronounced vanilla notes. Some have a longer finish; others are stronger. Even the proof ranges, from 120 to 125. (8/15/17)"
