Redbreast Tawny Port Cask Edition is a single pot still Irish whiskey initially matured in a combination of bourbon and oloroso sherry casks. The whiskey was then finished in Tawny Port casks for a number of years, adding a new dimension to the profile used in the expression. All of the whiskeys then completed their maturation journey by marrying in freshly seasoned tawny port hogsheads for a final maturation period of 14-25 months.
