The nose is full of beer; spicy and hoppy. It's very similar to Charbay's R5. The palate is also beer heavy with a discernible hops; it even has a prickly mouthfeel as if it were slightly carbonated. It definitely has a young taste to it, a bit raw and new makey, again not unlike Charbay's R5 and S whiskeys, but the strong hoppy taste mitigates some of that youth. The finish is exactly what you would expect after a good IPA, slightly bitter and a bit hoppy.
I'm not sure I've ever had a whiskey that tastes this much like beer.
