WineFrog explains Finished Whisky
The process of creating finished whiskey ranges from 6 months to 2 years. The cask used for finishing process is often a different from the original cask to add a unique taste. Given that the cask is a major contributor of flavor to a whiskey, the smallest change during the finishing period can have an enormous effect on the taste of the whiskey.
Many whiskey makers and whiskey enthusiasts percieve the finishing process as a contributor of new flavors by using varieties of cask. Some popular finned whiskey include: Balvenie Doublewood and Glenmorangie Port Wood.
