Pure pot still whiskey is only found in Irish Whiskey.Blended Whiskey Part malt and part grain combined in any possible combination of amounts. Blended whiskeys generally contain whiskey from different distilleries thus will be labeled with a brand but not a specific distillery.Cask Strength Usually reserved for only the finest of whiskey bottles, Cask Strength whiskey is taken directly from the Cask without being diluted. Typically, whiskey is diluted (with spring water) in an effort to make the taste less intense and more palatable for the consumer. In these high end whiskey samples, either the taste is already acceptable due to the high quality of the whiskey or the consumer can dilute the whiskey to cater to his or her own individual palette.Age The age of a whiskey does not refer to how long it has been in its bottle, thus it will do no good to attempt to age your own whiskey, rather the time it spends in the cask prior to being bottled.
