According to the company's promotional material, likely the first whiskey aged in Canadian oak--it's the same species of oak as found in the US, but environmental differences supposedly create some differences (the wood is tigher, less porous, heavier in vanillans, supposedly). Good quality, but a bit overpriced, and is desperately crying out for more proof. Flavours of toffee, butterscotch, big vanilla, rye spiciness, cinnamon hearts, orange peel, rye bread, berries, tobacco. Fresh cut lumber on the taste, a nice blend of sweet and spicy. But quite soft, and the flavours require a lot of teasing out. Gets drowned out in cocktails, and honestly--while it's better than its younger brother, Forty Creek Copper Pot--it's not so much better as to justify the $30 higher pricetag).
