The nose has a whiff of that pickle juice that's typical in these Canadian ryes but with a bit of vanilla as well. The palate has a nice balance of sweet and spicy rye notes, caramel and plenty of brine but the brine overwhelms by late palate. A drop of water brings out the vanilla notes and really enhances it, smoothing out some of the rough edges. The finish is briny and slightly bitter.
This is very similar to the standard WhistlePig. It's exactly what you would expect from a cask strength version. I actually prefer the standard 10 year old which has more balance. The brine in this one tends to take over.
