Try Breckenridge of Breckenridge, CO. It's aged only two years, but it is excellent.
I live on the bourbon trail in Kentucky, so I do have my loyalties /grin
However, I read some articles and reviews after reading your post. I will take a look and see if it is even available here. It could very well not be sold here. I've not noticed any non-Kentucky bourbons. But you have piqued my curiosity. Thanks.
