Aging whisky in casks used to age other liquor has become a big trend lately. Crown Royal has created a new whisky with a cognac finish. The Crown Royal Cask No. 16 is Canadian whisky aged in cognac casks made of oak from the renowned Limousin Forest in France. Crown Royal is a blend of more than 50 different individually aged whiskies which are then placed in the casks which give the blend a fruity and spicy finish.
