Step 1Pour the bottle of whiskey into a large, sealable nonreactive container. Add the brown sugar, stirring until it is dissolved. Add the cinnamon sticks and chiles. Cover and place in a cool, dark place for about 5 days, or until desired flavor is achieved. Remove and discard the cinnamon sticks and chiles. The whiskey will keep, at room temperature, for 3 to 6 months.
