Notes from John Hall, Whisky Maker A few years ago, I had the opportunity to purchase some outstanding bourbon barrels from Kentucky. These barrels are excellent for ageing whiskies because they are seasoned. This means most of the fresh harsh oak tannins have been removed and what remains is all the good stuff, such as the softer oak tannins, wood vanillas, sugars and the toasty, smokey, spicy aromas, as well as the caramelized flavours from the heavy charring of the inside of the barrel. After ageing my rye, barley and corn whiskies in their own special barrels, I decided to bring them together as a meritage, and placed the three whiskies into the bourbon barrels. This double barreling allowed the whiskies to hang out together and take on the subtle qualities offered by the bourbon barrels to enhance the finishing of the whisky.
