All whiskeys are kosher (for year round use, not for Passover)
In previous versions of this answer, someone stated that Whiskey must be "mevushal". Mevushal (a cooking process) is a special process for wine only, not other liquors. Wine which has been cooked may be handled by non-Jews, and wine which has not been made "mevushal" must not be handled by non-Jews once opened.
In terms of what is required for whiskey to be kosher, Whiskey, like other forms of alcohol, follow a simple rule: the process must not include contact with treif (non-knosher food) and may be opened, drunk and served by Jews and non-Jews alike.
