Tried neat- wow, not expecting a pour this smooth. I'm inclined to say that it doesn't need any water or ice... Tried on the rocks- not bad at all, definitely above average, but I think this bourbon is best enjoyed neat or with some water, depending on preference. Once the temperature dropped, I felt like it wasn't as smooth on the finish. Tried with splash of water- I think that my first inclination was right. Neat or slightly diluted is the best way to enjoy this one
