Of the 3 varieties of Gretzky Whisky, Ice Cask offers the most unique flavor profile, along with having the most bourbon character due to its higher corn content. I find it is best enjoyed neat. As of July 2017, it is only available at the Gretzky Winery & Distillery in Niagara-On-The-Lake ($60 CAD), which is a shame as it is considerably superior to the Red Cask, widely sold through retail liquor stores. It is also more distinct and a much better value than the premium "99 Proof" offering ($99 CAD), which is highly similar to Canadian Club 12-year / Small Batch.
