Jameson Single Pot Still. A celebration of the traditional style of Irish whiskey making after which it is named. Crafted from a mashbill of malted and unmalted barley, it is then triple distilled for a rich, unmistakable silkiness. This Five Oak Cask Release is matured in a combination of three different types of virgin oak (Irish, European and American) in addition to ex-Bourbon and ex-Sherry casks. The finished result is a whiskey that is equal parts complex and smooth.
