Nose: There's quite a bit going on here. The rye is mild and sweet, like beery rye bread, or rye and ginger biscuits (are they a thing?). It's also fruity, in a sappy green apple kind of a way, then there's an emulsion paint note. Before you stop reading, I should explain that "emulsion paint" is an aroma I often find in Scottish Grain whiskies and bourbons. It's not a bad thing, it's just a Quercus Alba thing that I haven't figured out the correct name for yet. I like it when I find emulsion paint in a whisk(e)y. The whiskey is very soft on the nose and not spiritous at all.
Palate: sweet, rounded, and mouth coating or slightly oily. Mild nutty rye bread spice, burnt bread, well fired Scotch morning rolls. After a while it becomes much more fruity: specifically apples and pears. Towards the finish it dries out a little, and develops a prickly warmth. With time I also found a mineral quality in it, which I liked.
Conclusion: There's lots of soft rye spice, but rather less of the toffee, coconut, and caramel notes that white oak imparts to most American whiskies. It's also much fruitier than I expected it to be. Whilst it's not life-altering, it's a very enjoyable drop. I reckon that it's over-priced, but that likely reflects the hype surrounding Whistlepig. Perhaps Mr Bhakta belongs to the "There's no such thing as bad publicity" school of thought.
