Finishing (whisky)

Finishing (also known as double matured or wood-finished) is the procedure that some whiskeys undergo whereby the spirit is matured in a cask of a particular origin and then spends time in a cask of different origin (generally 6 months to 2 years.) Typically, the first cask is an American oak cask formerly used to mature bourbon. The second cask may be one that has been used to mature some sort of fortified wine, often sherry, though sometimes port, madeira, or even wines such as red burgundy or chardonnay are used.
