is the procedure that some single malt Scotch whisky
undergoes whereby the spirit is matured in a cask of a particular origin and then spends time in a cask of different origin. Typically, the first cask is an American oak
cask formerly used to mature bourbon
. The second cask is usually one that has been used to mature some sort of fortified wine
, often sherry
, though sometimes port
, or even standard wines such as burgundy
Some of the more well-known finished whiskies include Balvenie "Double Wood", which is finished in sherry casks, Glenlivet "American Oak Finish" and "French Oak Finish", which are finished in brand-new casks of the respective woods, and the Glenmorangie range of sherry, port, madeira, and burgundy finishes.
