I have no idea what scottr is on or why he's rated twice but i'm with the other reviewers if it's the same batch i'm tasting 21b-20 this is fantastic stuff. Man from the low to the high but still reasonably priced end Knob Creek make great stuff. It has that bourony profile I'm not a huge fan these days but it executes so well I can't give it any less than a 4.25 it'd be a 4.5 or higher if I enjoyed the type of flavor profile. Straight pour and drink it went down so so smoothly without a drop of water. This thing is so bulletproof adding a liberal helping of water seemed to make zero difference to either the flavor and amazingly how strong it tasted. It tasted just the same without it.
