The term “rare cask” gets tossed around in Scotland. It’s code for expensive, not necessarily rare, but J.P. Wiser’s has made true on their promise to produce rare whiskies that are also quite affordable (often around $60 Canadian). The first in the series, Last Barrels, sold exclusively in Ontario through the LCBO. Not long after, the BC Liquor Board wanted their own special release. They received Union 52. That was 2016. With the success of those two releases, J.P. Wiser’s has gone all in with the Rare Cask series. Dissertation is a continuation of this whisky conversation of new types of Canadian whisky releases.
