Sweet oaky caramel, rich deep oak (mossy, old, but very sweet like a damp bourbon warehouse), spicy rye, but it’s balanced with the nicest set of light fruit like white grapes and white mulberries. It is very reminiscent of good, cask strength Buffalo Trace compared to a cask strength blended Canadian whisky with less of a focus on oak.
This is extremely pleasant at 53.5%, the nose is best a bit lower ABV, but it is still awesome for its sheer power at 66.9%. It’s one of the most dynamic whiskies I’ve ever encountered in terms of how it changes with ABV. If you have one of these and find it too hot, just keep adding distilled water until it’s to your taste. The drinking experience does not suffer.
